Clinical trials

The goal of this interventional study is to evaluate the effect of multichannel functionnal electrical stimulation for subchronic stroke gait rehabilitation. The main questions it aims to answer are: * Does this new therapy help improve walking speed? * Evaluate other aspects of therapeutic effectiveness such as different aspects of walking endurance, mobility, postural instability and autonomy. * Evaluate physiological aspects of autonomous gait such as spasticity, muscle strength and motor and sensorimotor recovery. * Evaluate the acceptability of this new therapy and its effect on quality of life.

The goal of this interventional study is to evaluate the effect of three different designs of trunk assistance exoskeletons on cumulative lumbar load, trunk extensors' muscular fatigue and comfort in healthy volunteers. The main questions it aims to answer is: will exoskeletons reduce muscle fatigue and cumulative lumbar load. Participants will : * get each exoskeletons adjusted and then practice the lifting task and measurement sequence in a first session * perform a lifting task for 4 blocks of 20 minutes on different sessions for each exoskeleton, another session is performed without assistance.
