Summary

he aim of the "RE PAR EX" research is to evaluate the feasibility of the instrumented examination of the effects of eccentric muscle strengthening in paralytic patients. This project is part of the research axis of the movement analysis laboratory. Following a stroke or spinal cord injury, patients develop a spastic paresis syndrome, which is characterized by the appearance of paresis, musculo-tendinous retractions and muscular hyperactivities. If the traditional treatments proposed (stretching, motor work) show limits, the use of eccentric muscle strengthening in paresis patients has been developing for about ten years, with results superior to the usual treatments. The results of the studies evaluating it are focused on clinical evaluations and do not make it possible to identify the precise origin of the observed responses. A pathophysiological understanding of the therapeutic effects of eccentric strengthening would be possible through instrumented examination of muscle structure and function, combining dynamometry, ultrasound, elastrography and electromyography (EMG). However, the feasibility of this quantified instrumental examination in paretic patients during a strengthening protocol has not been evaluated. The feasibility of a quantified instrumented examination in this setting is the aim of this research, a necessary prerequisite for a larger interventional study to evaluate the biomechanical and neurophysiological effects of eccentric muscle strengthening in paretic patients.

Conditions

• Paralysis

Type	Name	Description
OTHER	Instrumented assessment of muscle function	During the instrumented evaluations, we will evaluate the possibility of measuring the passive and active function of the muscle using: - an isokinetic dynamometer, an ultrasound and elastography device, an electrical stimulation of the calf nerve
