A method for diagnosis and/or training of proprioceptor feedback capabilities of a muscle and joint system of a human patient using an exercise system having a patient attachment device and an arrangement for controlling parameters of an exercise movement in response to a control signal derived from one or more measured exercise parameters. A patient performance goal is defined as a real time function of preselected exercise parameters. A perturbation signal function is defined for the control signal; and the control signal is modified by the perturbation function value during a patient exercise motion. The defined performance goal is displayed during the patient exercise motion and the actual patient performance relative to the performance goal is also tracked and displayed. An error value is measured as the difference between actual patient performance and the patient performance goal.
