Abstract

A method for diagnosis of a sleep-related condition of a patient. The method includes receiving physiological signals from sensors (24, 26, 27) coupled to the lower body of the patient, and analyzing the physiological signals, independently of any electroencephalogram (EEG) or electro-oculogram (EOG) signals, in order to identify sleep stages of the patient.
