Researchers are investigating whether adding local vibration sessions to the dorsiflexor muscles of the affected leg can improve neuromotor recovery in patients who are in the subacute phase after a stroke. This study compares two groups of stroke patients one receiving vibration therapy alongside standard rehabilitation and the other receiving sham vibration with standard rehabilitation. The main goal is to see if this vibration program can help patients walk faster. The treatment involves 40 sessions over 8 weeks during hospitalization, with five sessions per week. One group receives actual vibration therapy at a frequency of 100Hz on the dorsiflexor muscles, while the other group receives sham vibration without effective stimulation. Both groups also continue with the usual rehabilitation program for stroke recovery. Participants will undergo various assessments including walking speed measured by a 10-meter walk test at 2 months, and other walking performance tests over several months. Additional evaluations include motor function, spasticity, autonomy in walking, muscle strength, and neuromuscular fatigue using tools like electromyograms and gait analysis. These tests occur at different timepoints up to 4 months to monitor recovery and treatment effects.
