MEDICAL REHABILITATION GONIOMETRICAL SYSTEM

Physiological rehabilitation is applied in medical practice to restore a person's functional ability after musculoskeletal
injuries. Movements in the joints are the main functional indicator of the activity of the organs of support and movement.
The paper considers a resistive goniometric sensor in the form of a ball joint. Based on such a sensor, a medical rehabilitation
goniometric system is developed. It includes also a data collection device (autonomous data recorder) and a portable modem.

Computation of positive stable realizations for discrete-time linear systems

Sufficient conditions for the existence of positive stable realizations for given proper transfer matrices are established. Two methods are proposed for determination of the positive stable realizations for given proper transfer matrices. The effectives of the proposed procedures is demonstrated on numerical examples.
