Definitions
- the present invention relates to a therapeutic traction apparatus, and in particular, to a multi-axis traction device with a first body supporting portion moveable relative to a second body supporting portion and a method of using the therapeutic apparatus to apply traction to a patient.
- Traction tables are used to apply traction forces to the human body through the application of tension force along the spinal column. Traction tables are generally used to relieve pain in two areas, the lumbar region, which is located between a patient's ribs and hipbones, and the cervical region, which corresponds to the patient's neck region.
- a traditional system for applying traction to a patient is through the use of weights and pulleys.
- the method entails placing a patient in the supine position and securing the patient to a resting surface. Cords are then extended from the patient, looped around suspended pulleys and tied to raised weights which are released to provide a gravitational force. The weights thereby apply traction to the patient's back.
- the system has had only limited success because it does not sufficiently isolate the region of the body to which the force is to be applied.
- the system does not adequately treat patients with painful postural deformities, such as for example a flexed, laterally shifted posture often seen in patients suffering from a herniated lumbar disc.
- the traditional system is based upon applying a linear force in a horizontal or vertical plane to achieve a particular force exertion on a specific joint or body location.
- the forces are typically generated using a static weight or force generating actuator.
- the forces applied in a vertical direction must manually account for weight of a body supporting portion of the system and weight of a human body to ensure that a correct force is applied to the intended location.
- the weight of the body supporting portion and the human body weight applied in a horizontal direction have a negligible effect and are typically applied directly without accommodation.
- traction is delivered in a horizontal plane (perpendicular to gravity)
- the effect of these forces is negligible.
- traction is delivered in a vertical plane, these forces must be accommodated for.
- Traditional traction methods and devices require that the clinicians manually take such weight effects on forces administered during traction into account.
- U.S. Pat. No. 4,890,604 discloses a traction assembly that applies traction under the inclined weight of the patient.
- the traction assembly includes a stationary stand supportable on a ground or floor surface and a table assembly connected to the stand.
- the table assembly includes a frame that is rotatably assembled to the stand for limited rotation about a horizontal axis.
- a flat platform or table is slidably assembled to the frame for back-and-forth movement under gravitational influence in a longitudinal direction perpendicular to the axis of rotation of the frame. Restraints are connected to the patient's ankles and head.
- the body Upon rotation of the frame on the stand to incline the platform, the body is put in traction according to the weight of the body and the degree of inclination.
- the degree of applied force depends upon the weight of the body and the inclination of the frame, rather than by an independently adjustable force.
- the assembly does not compensate for a patient's postural deformities. For example, a patient with a herniated lumbar disc may not be able to lie perfectly straight on the table, reducing the effectiveness of the gravitational force.
- the table does not sufficiently concentrate traction force on the specific area in need of treatment, for example, the lumbar region of the body.
- U.S. Pat. No. 4,995,378 discloses a therapeutic table with a frame and a table top having an upper-body section rigid with respect to the frame, and a lower-body section slidable with respect to the frame.
- the sections provide a separable surface for a patient to lie prone face down.
- Hand grips fixed with respect to the upper-body section extend upwardly of the plane of the table top. The patient grasps the hand grips with arms above the head.
- An anchor is connected to the lower-body section to which a pelvic belt can be connected.
- a cylinder and piston drive slides the lower-body section to increase and decrease the distance between the hand grips and the pelvic belt anchors.
- Dyer device avoids the use of weights and pulleys, he still requires a cumbersome harness anchored to the end of the lower-body section of the table. Dyer also requires the patient to lie prone and hold on to hand grips during treatment. The traction force is thus extended along the entirety of the patient's spine, rather than focusing the force to the lumbar region. Dyer does not disclose a multi-axis traction device that can compensate for patient postural deformities that hinder the application of traction forces along the spine.
- the present invention provides a multi-axis traction device that is capable of treating back pain for a patient with postural deformities that hinder the traditional application of longitudinal traction force along the spine.
- the present traction device isolates and concentrates traction force on specific areas of the body, for example, the lumbar region, without applying the force along the entirety of the patient's body.
- the present therapeutic apparatus comprises a support frame with first and second body supporting portions.
- the first body supporting portion is moveable relative to the second body supporting portion along a longitudinal axis.
- a high friction surface on at least one of the body supporting portions secures the patient to such body supporting portion during therapeutic treatment.
- a linking mechanism provides the first body supporting portion movement along a path relative to the second body supporting portion, the path comprising at least one rotational degree of freedom.
- the present invention includes a method and apparatus for determining an adjusted traction force for the patient.
- the first body supporting portion is positioned in a non-horizontal configuration.
- a compensating force related to a weight of the first body supporting portion, a weight of an applicable portion of a patient's body, and an angle between the first body supporting portion and a horizontal plane is determined.
- the compensating force is applied to a desired traction force to determine the adjusted traction force.
- the adjusted traction force is applied to the patient by moving the first body supporting portion relative to the second body supporting portion along the longitudinal axis to affect the distance between the first body supporting portion and the second body supporting portion.
- the compensating force is preferably subtracted from the desired traction force when the first body supporting portion is positioned below horizontal.
- the compensating force is preferably added from the desired traction force when the first body supporting portion is positioned above horizontal.

- the locked position is released using the handles indicated by the reference numerals.
- the operator manually releases one or more of the locking mechanisms 94 , 96 , 98 and positions the first body supporting portion 14 in the desired configuration. Releasing the handle re-engages the locking mechanism 94 , 96 , 98 .
- Positioning the first body supporting portion 14 along any combination of the three rotational degrees of freedom does not interfere with the movement of the sliding mechanism 54 along the longitudinal axis 18 .
- an apparatus of the present invention may also provide a head supporting portion 120 for generally supporting the head of the patient.
- Head supporting portion 120 is slidingly attached to frame 134 .
- the frame 134 is pivotally attached to platform portion 53 at pivot points 124 , 126 (See FIG. 2 ), and is adapted to move along path 122 .

- Head strap 121 can optionally be used to retain the patient's head to the head supporting portion 120 .
- a cervical traction assembly with adjustable neck wedges suitable for use in the present invention is disclosed in U.S. patent application Ser. No. 08/817,444, entitled Portable Traction Device and U.S. Pat. No. 6,171,273.
- the processor 70 preferably retains cervical traction protocols as well.
- FIG. 3 illustrates a patient being treated on an apparatus of the present invention.
- Support member 52 is adjusted to a height that easily facilitates a patient mounting the apparatus.
- First body supporting portion 14 is then moved along a path comprising at least one rotational degree of freedom to accommodate for any postural deformities of the patient.
- the patient is then placed and supported on the first and second body supporting portions 14 , 16 in either a prone or supine position, and is secured to first body and second body supporting portions 14 , 16 by securing system 20 .
- FIG. 3 illustrates a patient being treated on an apparatus of the present invention.
- Support member 52 is adjusted to a height that easily facilitates a patient mounting the apparatus.
- First body supporting portion 14 is then moved along a path comprising at least one rotational degree of freedom to accommodate for any postural deformities of the patient.
- the patient is then placed and supported on the first and second body supporting portions 14 , 16 in either a prone or supine position, and is secured to first body and
- securing system 20 comprises a first belt 30 connected to the support frame, near each side edge of first body supporting portion 14 and a second belt 32 is connected to second body supporting portion 16 in a similar manner.
- First belt 30 is tightened around the navel region of the patient, just above the iliac crests.
- Second belt 32 is tightened around the ribcage of the patient, just above the lumbar region. The belts may overlap slightly.
- first body supporting portion 14 is moved relative to second body supporting portion 16 along longitudinal axis 18 (see FIG. 1 ). As the distance between the first and second body supporting portion is increased, a traction force is applied to the patient's lumbar region by the first and second belts. Further, because the first body supporting portion 14 has been moved along a path comprising at least one rotational degree of freedom, the traction force is applied at an angle that compensates for a patient's postural deformities. As the distance between the first and second body supporting portions is decreased, the traction force applied to the patient's lumbar region is decreases.
- first body supporting portion 14 can be moved along a path comprising at least one rotational degree of freedom after the patient is secured to the table and even during the application of traction force to the patient.
- the table can be releasably retained anywhere along the path during treatment to accommodate the patient's condition. It may even be desirable to retain first body supporting portion 14 at multiple locations along a path during a treatment cycle.
- the traction force created by first body supporting portion 14 moving away from second body supporting portion 16 along longitudinal axis 18 can be static (i.e.
- the patient can be treated in either the supine or prone position and/or both, without adjusting the apparatus.
- a treatment protocol can be entered into processor 70 to facilitate some or all of the therapeutic steps.
- processor 70 provides a touch control screen to assist a health care professional in entering the treatment protocol.
- Data input such as the mode of lumbar treatment (e.g. static or intermittent), force ramp up time, force ramp down time, hold time, rest time, rest force, maximum force, and treatment time can all be entered to create a desired treatment protocol.
- the processor 70 communicates with the power source (in the illustrated embodiment the source of compressed air 68 ) to power the actuators 56 , 66 , 128 and to provide the designated movement between the first body supporting portion, second body supporting portions, and/or the head supporting portion 14 , 16 , 120 .
- Performance characteristics of the present invention include improved ability to treat patients with postural deformities, greater ease in the treatment of patients, and reduced set-up time.
- an apparatus of the present invention can treat patients with postural deformities who could not be adequately treated with conventional traction devices.
- the securing system 20 provides a more efficient and less cumbersome mechanism of applying traction force to a patient.
- a single or series of patients can be treated in either the prone or supine position or both, without adjusting or altering an apparatus of the present invention.
- the invention has improved performance characteristics, while also being easier and faster to use.
- FIG. 8 is a schematic view of the therapeutic apparatus 10 generally as illustrated in FIG. 1 with the first body supporting portion 14 rotated down from a neutral (horizontal) position relative to the horizontal plane 204 .
- the downward slope of the first body supporting portion 14 can cause the traction force to be greater than intended due to the influence of gravity. That is, gravity acting on the first body supporting portion 14 and the portion of the patients body supported thereon adds the forces 224 and 226 to the desired traction force 230 .
- the present invention uses the force vectors for the weight 222 of the tilted first body supporting portion 14 and the weight 220 of the applicable portion of the patient's body 202 supported by the body supporting portion 14 to calculate a compensating force along the longitudinal axis 18 of the tilted first body supporting portion 14 .

- the compensating forces 224 and 226 are either added to or subtracted from a delivered traction force 230 depending upon whether the first body supporting portion 14 is rotated up or rotated down from its neutral position on the horizontal plane 204 . As shown in FIG. 8 , when the first body supporting portion 14 is rotated down from its neutral position, the compensating forces 224 and 226 will be subtracted from the delivered traction force 230 .
- FIG. 9 is a schematic view of the therapeutic apparatus 10 generally as illustrated in FIG. 1 with the first body supporting portion 14 rotated up from its neutral (horizontal) position relative to the horizontal plane 204 . Again, due to the influence of gravity the upward slope of the first body supporting portion 14 may cause the traction force to be less than intended. When the first body supporting portion 14 is rotated up from its neutral position, the compensating forces 224 and 226 is typically added to the delivered traction force.

Abstract
Description
- The present application is a continuation of U.S. patent application Ser. No. 10/715,008, filed Nov. 17, 2003, entitled “Multi-Axis Cervical and Lumber Traction Table”, which is a continuation-in-part application of U.S. patent application Ser. No. 10/054,631, filed Jan. 22, 2002, entitled, “Multi-Axis Cervical and Lumber Traction Table”, the entire disclosures of which are hereby incorporated by reference for all purposes.
- The present invention relates to a therapeutic traction apparatus, and in particular, to a multi-axis traction device with a first body supporting portion moveable relative to a second body supporting portion and a method of using the therapeutic apparatus to apply traction to a patient.
- Back and neck pain are common conditions that can adversely affect both work and leisure activities. One commonly used non-surgical approach to alleviating back pain in patients is the application of traction forces. Traction tables are used to apply traction forces to the human body through the application of tension force along the spinal column. Traction tables are generally used to relieve pain in two areas, the lumbar region, which is located between a patient's ribs and hipbones, and the cervical region, which corresponds to the patient's neck region.
- A traditional system for applying traction to a patient is through the use of weights and pulleys. The method entails placing a patient in the supine position and securing the patient to a resting surface. Cords are then extended from the patient, looped around suspended pulleys and tied to raised weights which are released to provide a gravitational force. The weights thereby apply traction to the patient's back. The system has had only limited success because it does not sufficiently isolate the region of the body to which the force is to be applied. In addition, the system does not adequately treat patients with painful postural deformities, such as for example a flexed, laterally shifted posture often seen in patients suffering from a herniated lumbar disc.
- Furthermore, the traditional system is based upon applying a linear force in a horizontal or vertical plane to achieve a particular force exertion on a specific joint or body location. The forces are typically generated using a static weight or force generating actuator. The forces applied in a vertical direction must manually account for weight of a body supporting portion of the system and weight of a human body to ensure that a correct force is applied to the intended location. The weight of the body supporting portion and the human body weight applied in a horizontal direction have a negligible effect and are typically applied directly without accommodation. When traction is delivered in a horizontal plane (perpendicular to gravity), the effect of these forces is negligible. When traction is delivered in a vertical plane, these forces must be accommodated for. Traditional traction methods and devices require that the clinicians manually take such weight effects on forces administered during traction into account.
- U.S. Pat. No. 4,890,604 (Nelson) discloses a traction assembly that applies traction under the inclined weight of the patient. The traction assembly includes a stationary stand supportable on a ground or floor surface and a table assembly connected to the stand. The table assembly includes a frame that is rotatably assembled to the stand for limited rotation about a horizontal axis. A flat platform or table is slidably assembled to the frame for back-and-forth movement under gravitational influence in a longitudinal direction perpendicular to the axis of rotation of the frame. Restraints are connected to the patient's ankles and head. Upon rotation of the frame on the stand to incline the platform, the body is put in traction according to the weight of the body and the degree of inclination.
- One shortcoming of the device disclosed in Nelson is that the degree of applied force depends upon the weight of the body and the inclination of the frame, rather than by an independently adjustable force. Furthermore, the assembly does not compensate for a patient's postural deformities. For example, a patient with a herniated lumbar disc may not be able to lie perfectly straight on the table, reducing the effectiveness of the gravitational force. Further yet, because the patient is anchored to the table at the neck and ankles, the table does not sufficiently concentrate traction force on the specific area in need of treatment, for example, the lumbar region of the body.
- U.S. Pat. No. 4,995,378 (Dyer et al.) discloses a therapeutic table with a frame and a table top having an upper-body section rigid with respect to the frame, and a lower-body section slidable with respect to the frame. The sections provide a separable surface for a patient to lie prone face down. Hand grips fixed with respect to the upper-body section extend upwardly of the plane of the table top. The patient grasps the hand grips with arms above the head. An anchor is connected to the lower-body section to which a pelvic belt can be connected. A cylinder and piston drive slides the lower-body section to increase and decrease the distance between the hand grips and the pelvic belt anchors.
- Although the Dyer device avoids the use of weights and pulleys, he still requires a cumbersome harness anchored to the end of the lower-body section of the table. Dyer also requires the patient to lie prone and hold on to hand grips during treatment. The traction force is thus extended along the entirety of the patient's spine, rather than focusing the force to the lumbar region. Dyer does not disclose a multi-axis traction device that can compensate for patient postural deformities that hinder the application of traction forces along the spine.
- The present invention provides a multi-axis traction device that is capable of treating back pain for a patient with postural deformities that hinder the traditional application of longitudinal traction force along the spine. The present traction device isolates and concentrates traction force on specific areas of the body, for example, the lumbar region, without applying the force along the entirety of the patient's body.
- The present therapeutic apparatus comprises a support frame with first and second body supporting portions. The first body supporting portion is moveable relative to the second body supporting portion along a longitudinal axis. A high friction surface on at least one of the body supporting portions secures the patient to such body supporting portion during therapeutic treatment. A linking mechanism provides the first body supporting portion movement along a path relative to the second body supporting portion, the path comprising at least one rotational degree of freedom.
- The present invention includes a method and apparatus for determining an adjusted traction force for the patient. The first body supporting portion is positioned in a non-horizontal configuration. A compensating force related to a weight of the first body supporting portion, a weight of an applicable portion of a patient's body, and an angle between the first body supporting portion and a horizontal plane is determined. The compensating force is applied to a desired traction force to determine the adjusted traction force. The adjusted traction force is applied to the patient by moving the first body supporting portion relative to the second body supporting portion along the longitudinal axis to affect the distance between the first body supporting portion and the second body supporting portion.
- The compensating force is preferably subtracted from the desired traction force when the first body supporting portion is positioned below horizontal. The compensating force is preferably added from the desired traction force when the first body supporting portion is positioned above horizontal.

FIG. 1 illustrates atherapeutic apparatus 10 including asupport frame 12 having a firstbody supporting portion 14 and a secondbody supporting portion 16. Firstbody supporting portion 14 is capable of movement relative to secondbody supporting portion 16 along alongitudinal axis 18. As used herein, the term “longitudinal axis” refers to the axis along which a body supporting portion can be displaced. InFIG. 1 , firstbody supporting portion 14 is adapted to generally support a patient's lower body while secondbody supporting portion 16 is adapted to support a patient's upper body. The present invention also contemplates the reverse (i.e. first body supporting portion supporting the patient's upper body and the second body supporting portion supporting the patient's lower body). - The
therapeutic apparatus 10 further includes a securingsystem 20 adapted to secure a patient to the first and secondbody supporting portions mechanism 22 is adapted to provide movement of the firstbody supporting portion 14 relative to secondbody supporting portion 16 along a path comprising at least one rotational degree of freedom. As used herein, “rotational degree of freedom” refers to rotational movement of a first body supporting portion relative to a second body supporting portion. Although the embodiment inFIG. 1 shows firstbody supporting portion 14 in a neutral position (i.e. along the same horizontal plane as the second body supporting portion 16), first body supporting portion is adapted to move along a path comprising up to three degrees of freedom, including, but not limited to yaw movement alongpath 24, pitch movement alongpath 26, roll movement alongpath 28, or a combination thereof. - Securing
system 20 is adapted to secure a patient to the first and secondbody supporting portions FIG. 1 , securingsystem 20 includes afirst belt 30 attached to thesupport frame 12, and extending at least to each side edge of firstbody supporting portion 14, and asecond belt 32 attached to thesupport frame 12 and extending at least to each side edge of secondbody supporting portion 16 in a similar manner. InFIG. 1 , first andsecond belts system 20 can be a Velcro® or other high friction surface on thebody supporting surfaces belts -
FIG. 2 illustrates an exploded view of the presenttherapeutic apparatus 10.Support frame 12 includes abase portion 50, asupport member 52, and aplatform portion 53.Base portion 50 supports the apparatus and is positioned on a generally horizontal surface.Support member 52 is secured tobase member 50 at alower portion 59, and toplatform portion 53 at anupper portion 63.Support member 52 is thereby positioned in a vertical plane and is adapted to provide support for the first and second body supporting portions.Support member 52 also includes an actuator (not shown) for increasing or decreasing the height of the first and second body supporting portions relative to thebase portion 50. Suitable actuators include pneumatic or hydraulic cylinders, linear motors, worm gears, rack and pinion systems, and the like. Preferably,support member 52 is capable of adjustment between about 25 inches to about 35 inches and is powered by a central source ofcompressed air 68. - In the illustrated embodiment, the second
body supporting portion 16 is rigidly attached to atop side 51 ofplatform portion 53 and is positioned along a substantially horizontal plane. Firstbody supporting portion 14 is pivotally secured toplatform portion 53 by linkingmechanism 22. As shown inFIG. 2 , linkingmechanism 22 comprisescantilever arm 58,yaw mechanism 60,pitch mechanism 62 androll mechanism 64.Cantilever arm 58 is pivotally attached to pitchmechanism 62 byyaw mechanism 60 at pivot point 61 (SeeFIG. 6 ).Pitch mechanism 62 is pivotally attached toplatform portion 53 at pivot points 65 and 67.Roll mechanism 64 is pivotally attached tocantilever arm 58 at pivot points 71 and 73. Anactuator 66 can be secured to pitchmechanism 62 atlever 69, the actuator being adapted to facilitate movement along a path comprising at least one rotational degree of freedom, preferably facilitating at least pitch movement along path 26 (seeFIG. 1 ). Almost any type of actuator can be used, however, an actuator of the present invention is preferably powered by a single central source ofcompressed air 68. - Sliding
mechanism 54 is slidably attached to rollmechanism 64. In the illustrated embodiment, slidingmechanism 54 includesrollers 55 that slide intracks 57 onroll mechanism 64, although a variety of structures could be used. Firstbody supporting portion 14 is secured to slidingmechanism 54 and is thereby capable of movement alonglongitudinal axis 18, as shown inFIG. 1 . Preferably, firstbody supporting portion 14 is capable moving up to 6 inches alonglongitudinal axis 18.Actuator 56 can be secured to slidingmechanism 54 to facilitate movement of the first body supporting portion alonglongitudinal axis 18. Any type of suitable actuator can be used, including a pneumatic actuator, hydraulic actuator, rack and pinion structures, linear motors, worm gear, solenoids, and the like. In the illustrated embodiment,actuator 56 is a double acting piston powered by a central source ofcompressed air 68 and is capable of moving firstbody supporting portion 14 alonglongitudinal axis 18 with a force of up to about 200 pounds. - The present
therapeutic apparatus 10 permits theactuator 56 to apply or remove a traction force to the patient without interfering with the operation of theyaw mechanism 60,pitch mechanism 62 orroll mechanism 64. In particular, any one or all of theyaw mechanism 60,pitch mechanism 62 androll mechanism 64 can be adjusted before, during or after a traction force is applied to a patient. Thetherapeutic apparatus 10 has the added advantage that there are no rope and pulleys to interfere with the operation of theyaw mechanism 60,pitch mechanism 62 and/orroll mechanism 64 during traction. -
Processor 70 receives input data, processes that data and communicates with a central source ofcompressed air 68 in response. In the illustrated embodiment, the processor has a digital display, incorporating touch screen capabilities.Processor 70 is adapted to receive, process and communicate to the traction apparatus almost any relevant treatment data, including the type of force (e.g. static or intermittent), force ramp up and ramp down times, force hold and rest times, magnitude of hold and rest forces, and treatment times. Optionally, theprocessor 70 is adapted to automatically adjusting the table height and/or pitch movement of the apparatus, as well as a patient control switch adapted to terminate treatment. As used herein, “processor” refers to any of a variety of general purpose or special purpose programmable computing devices, such as for example a PC or a programmable logic controller. In one embodiment, theprocessor 70 is a separate stand-alone computer, such as a PC. - The
processor 70 can also store and retrieve pre-programmed traction protocols. For example, the therapist may develop a protocol for a particular patient that can be applied multiple time over the course of treatment. This protocol can be stored in theprocessor 70 for future use. A protocol can include any of the treatment variable available in theprocessor 70, including without limitation the type of force (e.g. static or intermittent), force ramp up and ramp down times, force hold and rest times, magnitude of hold and rest forces, and treatment times. Theprocessor 70 also preferably assigns an index number or title to each protocol so that they can be easily retrieved. In another embodiment, the therapist generates a treatment protocol off-line on a separate computer system, such as a PC. The protocol is then uploaded to theprocessor 70 using conventional computer communication protocols and techniques, such as an RS-232 connection. This embodiment permits the treatment protocol to be sent electronically to other clinics at which the patient can receive treatment. One method of electronically transmitting a treatment protocol is using electronic mail over the Internet. -
FIGS. 4, 5 and 6 show views of a portion of the present invention and illustrate examples of different rotational degrees of freedom of which firstbody supporting portion 14 is adapted to move relative to secondbody supporting portion 16. For example, inFIG. 4 ,roll mechanism 64 is pivotally secured tocantilever arm 58 at pivot points 71 and 73 to provide roll movement alongpath 28 aboutaxis 90. It is preferable thatroll mechanism 64 be capable of providing firstbody supporting portion 14 with up to about 15 degrees of rotation from the neutral position in either a clockwise or counterclockwise direction. - In
FIG. 5 , yaw mechanism 60 (seeFIG. 6 ) is pivotally attached to pitchmechanism 62 at pivot point 61 (seeFIG. 6 ) and is adapted to rotatecantilever arm 58 aboutaxis 100 to provide yaw movement of the first body supporting portion 14 (seeFIG. 1 ) alongpath 24. Preferably,yaw mechanism 60 is capable of providing the firstbody supporting portion 14 up to about 15 degrees of rotation in either direction from the neutral position. - In
FIG. 6 ,pitch mechanism 62 is secured toplatform portion 53 at pivot points 65 and 67 and is adapted to rotatecantilever arm 58 aboutaxis 110 to provide pitch movement alongpath 26, as shown inFIG. 1 . AlthoughFIG. 6 illustrates rotation flexed above the neutral position, embodiments of the present invention can also extend below neutral. Preferred embodiments of the present invention are capable of flexing up to about 25 degrees and extending down to about 20 degrees from the neutral position. - Although
FIGS. 4, 5 and 6 each illustrate movement along a path defined by one rotational degree of freedom (e.g., pitch, roll or yaw), the presenttherapeutic apparatus 10 is capable of movement along paths that comprise two or more rotational degrees of freedom. That is, each of the rotational degrees of freedom are preferably independently and simultaneously adjustable. In a preferred embodiment, the first body supporting structure is capable of simultaneous movement along a path having three rotational degrees of freedom, comprising roll, yaw and pitch movement. - In the illustrated embodiment, the
longitudinal axis 18 comprises the axis of movement of the slidingmechanism 54 relative to thecantilever arm 58. This movement along thelongitudinal axis 18 is independent of the three degrees of freedom. The path upon which firstbody supporting portion 14 is positioned affects the direction and angle of its movement relative to secondbody supporting portion 16 alonglongitudinal axis 18. For example, if firstbody supporting portion 14 is positioned alongpath longitudinal axis 18 will be located 10 degrees above the location oflongitudinal axis 18 inFIG. 1 . - The present invention provides at least one locking mechanism for releasably retaining first
body supporting portion 14 along the path comprising at least one rotational degree of freedom. The apparatus may further provide a locking mechanism for releasably retaining the firstbody supporting portion 14 from movement alonglongitudinal axis 18. For example,FIG. 4 illustrates afirst locking mechanism 94 adapted to releasably retain firstbody supporting portion 14 from longitudinal movement.Second locking mechanism 96 is adapted to releasably retain firstbody supporting portion 14 from yaw movement alongpath 24 and third lockingmember 98 is adapted to releasably retain firstbody supporting portion 14 from roll movement alongpath 28. In another embodiment, at least one locking mechanism is provided for each rotational degree of freedom. In one embodiment, the lockingmechanisms - The locking
mechanisms mechanisms body supporting portion 14 in the desired configuration. Releasing the handle re-engages thelocking mechanism body supporting portion 14 along any combination of the three rotational degrees of freedom does not interfere with the movement of the slidingmechanism 54 along thelongitudinal axis 18. - As illustrated in
FIG. 7 , an apparatus of the present invention may also provide ahead supporting portion 120 for generally supporting the head of the patient.Head supporting portion 120 is slidingly attached to frame 134. Theframe 134 is pivotally attached toplatform portion 53 at pivot points 124, 126 (SeeFIG. 2 ), and is adapted to move alongpath 122. Preferably, theframe 134 is adapted to rotate at pivot points 124, 126 up to about 30 degrees from a horizontal plane.Locking mechanism 130 is provided for releasably retaining theframe 134 andhead supporting portion 120 at various locations alongpath 122. - The
head supporting portion 120 is adapted to move relative to frame 134 along anaxis 132 under the power ofactuator 128. Conventional ropes and pulleys are eliminated.Actuator 128 is preferably powered by the central source of compressed air 68 (seeFIG. 2 ) to generate the cervical traction force. In the presenttherapeutic apparatus 10, thesingle power source 68 operates all of theactuators Neck wedges 136 are preferably used to retain the patient's head to the head supporting portion 120 (seeFIG. 2 ). The location of theneck wedges 136 is preferably adjusted to accommodate patients of different sizes.Head strap 121 can optionally be used to retain the patient's head to thehead supporting portion 120. A cervical traction assembly with adjustable neck wedges suitable for use in the present invention is disclosed in U.S. patent application Ser. No. 08/817,444, entitled Portable Traction Device and U.S. Pat. No. 6,171,273. Theprocessor 70 preferably retains cervical traction protocols as well. - The present invention also provides a method of treating a patient with the apparatus generally described above.
FIG. 3 illustrates a patient being treated on an apparatus of the present invention.Support member 52 is adjusted to a height that easily facilitates a patient mounting the apparatus. Firstbody supporting portion 14 is then moved along a path comprising at least one rotational degree of freedom to accommodate for any postural deformities of the patient. The patient is then placed and supported on the first and secondbody supporting portions body supporting portions system 20. InFIG. 3 , securingsystem 20 comprises afirst belt 30 connected to the support frame, near each side edge of firstbody supporting portion 14 and asecond belt 32 is connected to secondbody supporting portion 16 in a similar manner.First belt 30 is tightened around the navel region of the patient, just above the iliac crests.Second belt 32 is tightened around the ribcage of the patient, just above the lumbar region. The belts may overlap slightly. - Next, first
body supporting portion 14 is moved relative to secondbody supporting portion 16 along longitudinal axis 18 (seeFIG. 1 ). As the distance between the first and second body supporting portion is increased, a traction force is applied to the patient's lumbar region by the first and second belts. Further, because the firstbody supporting portion 14 has been moved along a path comprising at least one rotational degree of freedom, the traction force is applied at an angle that compensates for a patient's postural deformities. As the distance between the first and second body supporting portions is decreased, the traction force applied to the patient's lumbar region is decreases. - Many variations of the above described method can be accomplished by an apparatus of the present invention. For example, to further treat a patient's postural deformities, first
body supporting portion 14 can be moved along a path comprising at least one rotational degree of freedom after the patient is secured to the table and even during the application of traction force to the patient. Further, the table can be releasably retained anywhere along the path during treatment to accommodate the patient's condition. It may even be desirable to retain firstbody supporting portion 14 at multiple locations along a path during a treatment cycle. Additionally, the traction force created by firstbody supporting portion 14 moving away from secondbody supporting portion 16 alonglongitudinal axis 18 can be static (i.e. constant application of a force during a period of time) or intermittent (application of greater force for a period of time followed by a lesser force for a period of time). Further yet, the patient can be treated in either the supine or prone position and/or both, without adjusting the apparatus. - Prior to beginning therapy, a treatment protocol can be entered into
processor 70 to facilitate some or all of the therapeutic steps. In a preferred embodiment,processor 70 provides a touch control screen to assist a health care professional in entering the treatment protocol. Data input such as the mode of lumbar treatment (e.g. static or intermittent), force ramp up time, force ramp down time, hold time, rest time, rest force, maximum force, and treatment time can all be entered to create a desired treatment protocol. Theprocessor 70 communicates with the power source (in the illustrated embodiment the source of compressed air 68) to power theactuators head supporting portion - Performance characteristics of the present invention include improved ability to treat patients with postural deformities, greater ease in the treatment of patients, and reduced set-up time. By providing an apparatus that is adapted to move along a path comprising at least one rotational degree of freedom, an apparatus of the present invention can treat patients with postural deformities who could not be adequately treated with conventional traction devices. Further, the securing
system 20 provides a more efficient and less cumbersome mechanism of applying traction force to a patient. Further yet, a single or series of patients can be treated in either the prone or supine position or both, without adjusting or altering an apparatus of the present invention. Thus, the invention has improved performance characteristics, while also being easier and faster to use. - In another embodiment of the present method, more accurate traction forces are provided by compensating for both the weight of the
body supporting portion 14 and the weight of the applicable portion of the patient supported by thebody supporting portion 14. For example,FIG. 8 is a schematic view of thetherapeutic apparatus 10 generally as illustrated inFIG. 1 with the firstbody supporting portion 14 rotated down from a neutral (horizontal) position relative to thehorizontal plane 204. The downward slope of the firstbody supporting portion 14 can cause the traction force to be greater than intended due to the influence of gravity. That is, gravity acting on the firstbody supporting portion 14 and the portion of the patients body supported thereon adds theforces traction force 230. - The present invention uses the force vectors for the
weight 222 of the tilted firstbody supporting portion 14 and theweight 220 of the applicable portion of the patient'sbody 202 supported by thebody supporting portion 14 to calculate a compensating force along thelongitudinal axis 18 of the tilted firstbody supporting portion 14. As used herein, the phrase “compensating forces” refers to force vectors along a longitudinal axis of a tilted body supporting portion of a therapeutic apparatus, which accommodate for the weight of the tilted body supporting portion and the weight of the applicable portion of the patient's body supported by the body supporting portion during traction. - To apply a desired traction force to the patient, the compensating
forces traction force 230 depending upon whether the firstbody supporting portion 14 is rotated up or rotated down from its neutral position on thehorizontal plane 204. As shown inFIG. 8 , when the firstbody supporting portion 14 is rotated down from its neutral position, the compensatingforces traction force 230. - In another example,
FIG. 9 is a schematic view of thetherapeutic apparatus 10 generally as illustrated inFIG. 1 with the firstbody supporting portion 14 rotated up from its neutral (horizontal) position relative to thehorizontal plane 204. Again, due to the influence of gravity the upward slope of the firstbody supporting portion 14 may cause the traction force to be less than intended. When the firstbody supporting portion 14 is rotated up from its neutral position, the compensatingforces - An estimate of the applicable portion of the patient supported by the body supporting portion can be calculated according to the following body mass distribution table.
TABLE 1 Percentage of Body Portion Total Body Mass Head/Neck about 8% Hips about 12% Thighs about 20% Lower Legs about 9.2% Feet about 3%
The mathematical formula for calculating the compensating forces is determined according to the equation below:
Compensating forces=Sin(Acute Angle Between Tilted Body Supporting Portion of Therapeutic Apparatus and Horizontal Plane)*(Weight of Tilted Body Supporting Portion+Weight of Applicable Portion of Patient)
Adjusting the delivered traction force by the compensating forces will yield an adjusted traction force. As used herein, the phrase “adjusted traction force” represents a traction force that is modified to take the compensating forces into account. The mathematical formula for calculating the adjusted force is determined according to whether the force of gravity increases or decreases the delivered traction force. If the body supporting portion is rotated down from its neutral position, then Adjusted Traction Force=Delivered Traction Force−Compensating Forces. If the body supporting portion is rotated up from its neutral position, then Adjusted Traction Force=Delivered Traction Force+Compensating Forces. - For example, the total body weight of a male patient on the
therapeutic apparatus 10 is about 200 pounds inFIG. 8 . His tiltedlower body 202 on the tilted first supportingportion 14 includes his hip, thighs, lower legs, and feet. In general, an ordinary human being's lower body weight is equal to approximately 44% of his or her total body weight. In this example, the patient'slower body weight 220 is about 88 pounds (200 pounds*44%). Theweight 222 of the tilted firstbody supporting portion 14 of thetherapeutic apparatus 10 is fixed at about 22 pounds. The first supportingportion 14 is rotated down about 10 degrees from thehorizontal plane 204. The compensatingforces
Sin(10°)*(22 pounds+88pounds)=17.4 pounds
Therefore, when delivering atraction force 230 of 150 pounds, an adjusted traction force of 132.6 pounds (150 pounds−17.4 pounds) should be applied to the patient. - Referring now to
FIG. 9 , the same male patient is treated in this example. The first supportingportion 14 is rotated up about 15 degrees from thehorizontal plane 204. The compensatingforces
Sin(15°*(22 pounds+88 pounds)=28.5 pounds
Therefore, when delivering atraction force 230 of 150 pounds, an adjusted traction force of 178.5 pounds (150 pounds+28.5 pounds) should be applied to the patient. - Referring to
FIG. 10 , the same male patient is treated in this example. At this time, thehead supporting portion 120 is rotated down about 10 degrees from thehorizontal plane 204. In general, an ordinary human being's head and neck weight is equal to approximately 8% of his or her total body weight. Here, theweight 234 of patient's head andneck 203 is about 16 pounds (200 pounds*8%). Theweight 236 of the tiltedhead supporting portion 120 of thetherapeutic apparatus 10 is fixed at about 4 pounds. The compensatingforces
Sin(10°)*(4 pounds+16 pounds)=3.5 pounds
Therefore, when delivering atraction force 232 of 150 pounds, an adjusted traction force of 146.5 pounds (150 pounds−3.5 pounds) should be applied to the patient. - Referring to
FIG. 11 , the same male patient is treated in this example. Thehead supporting portion 120 is rotated up about 5 degrees from thehorizontal plane 204. The compensatingforces
Sin(5°)*(4 pounds+16 pounds)=1.7 pounds
Therefore, when delivering atraction force 232 of 150 pounds, an adjusted traction force of 151.7 pounds (150 pounds+1.7 pounds) should be applied to the patient. -
FIG. 12 is a schematic view of the therapeutic apparatus generally as illustrated inFIG. 1 capable of automatically implementing the theory of the traction force adjustment discussed above. Thetherapeutic apparatus 10 includes an electricalangle measuring device 210, such as a potentiometer, attached to thepitch mechanism 62. In one embodiment, theangle measuring device 210 provides a signal corresponding to the angle a of first supportingportion 14 relative to thehorizontal plane 204. Theangle measuring device 210 can also measure the angle of the second supportingportion 16 and/or thehead support portion 120 relative to thehorizontal plane 204. Any device that generates a signal that is proportional to the angle α can be substituted for theangle measuring device 210, such as for example an absolute or incremental optical encoder. - For most applications, the second
body supporting portion 16 remains horizontal, while the firstbody supporting portion 14 and/or thehead supporting portion 120 can move relative to horizontal. It is also possible for the secondbody supporting portion 16 to move relative to horizontal. In some embodiments, theangle measuring device 210 is three discrete devices that generate angle signals for each of the firstbody supporting portion 14, the secondbody supporting portion 16 and thehead support portion 120. - A
weight measuring device 212 is optionally attached to thetherapeutic apparatus 10 to measure the total body weight of a patient. A signal from theweight measuring device 212 is transmitted to theprocess 70 and is used to calculate the adjusted traction force. In one embodiment, an operator identifies the portion of the patient supported by one of the supportingportions apparatus 10 is preferably stored in theprocessor 70. Theprocessor 70 uses theweight measuring device 212 to calculate the total weight of the patient. The body mass distribution data in Table 1, stored as a look-up table available to theprocessor 70 is used to calculate the weight of the patient supported by the relevantbody supporting portion - In another embodiment, a
weight measuring device body supporting portion 14, the secondbody supporting portion 16 and/or thehead support portion 120, respectively. Signals from the weight measuring devices 213 are preferably transmitted directly to theprocessor 70 for use in calculating the adjusted traction force. Providing multiple weight measuring devices 213 obviates the need to estimate the portion of the patient's body supported by aparticular support portion - In one embodiment, the
weight measuring device 212 provides a voltage signal representing the total weight of the patient. A percentage of the voltage from a voltage divider of thedevice 212 can be used to represent the weight of the tilted human body on the firstbody supporting portion 14. The weights of the tilted first and secondbody supporting portions body supporting portion 14. These voltage signals can be combined using electrical summing and multiplier circuits to provide a signal that represents the compensating forces. The signal that represents the compensating forces can be electrically summed with another signal that controls theactuator 56, so as to control the adjusted traction force that takes both the weight of the tilted firstbody supporting portion 14 and the weight of the applicable portion of the patient's body into account. Similarly, theweight measuring device 212 can also be used to control the adjusted traction force that takes both the weight of thehead support portion 120 and the weight of the head and neck of the patient into account - The electronic signals from the
angle measuring device 210 andweight measuring devices 212 and/or 213 can be directed to an electronic display indicating. The operator then uses this angle and weight information to calculate the adjusted traction force. In another embodiment, the signals from theangle measuring device 210 and theweight measuring devices 212 and/or 213 can be directed to theprocessor 70. Theprocessor 70 preferably measures the weight supported by the supportingportions body supporting portion processor 70 optionally includes a data entry device, such as a keypad. Theprocessor 70 then calculates the adjusted traction force. The adjusted traction force can be entered into theprocessor 70 by the operator or theprocessor 70 can control the operation of one or more of theactuators 56, 66 (seeFIG. 2 ) to apply the adjusted traction force. -
FIG. 13 is a schematic view of the therapeutic apparatus in accordance with the present invention. Thetherapeutic apparatus 10 includes adigital control system 220 capable of determining the angle α that the supportingportions FIG. 13 , the firstbody supporting portion 14 is tilted relative to thehorizontal plane 204. - The
digital control system 220 is also capable of measuring the total and partial body weight of a patient (seeFIG. 12 ). For example, the body weight percentage distribution information can be stored in thesystem 220, so that the weight of the applicable portion of the patient's body on the firstbody supporting portion 14 can be digitally computed. Alternatively, the weight supported by eachsupport portion digital control system 220. - In the embodiment of
FIG. 13 , the weight of the tilted firstbody supporting portion 14 is fixed and known at the time of manufacture. This weight is preferably stored in thedigital control system 220. Once the adjusted traction force is calculated, thedigital control system 220 controls theactuator 56 to apply the traction force. - All of the patents and patent applications disclosed herein, including those set forth in the Background of the Invention, are hereby incorporated by reference.
