Clinical Implementation of Multichannel Functional Electrical Stimulation Device for Gait Rehabilitation in Subchronic Stroke: A Feasibility Study

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.
