Researchers are evaluating the effects of a local vibration program applied to the dorsiflexor muscles on neuromotor recovery in patients undergoing subacute rehabilitation after a stroke. The study aims to determine if adding vibration therapy to a standard rehabilitation program improves walking speed compared to rehabilitation alone. The trial focuses on patients who have experienced ischemic or hemorrhagic strokes and are in the early recovery phase between 14 days and 3 months post-stroke. Participants will be randomly assigned to one of two groups: an experimental group receiving effective local vibrations at 100Hz on the paretic limb's dorsiflexor muscles, and a control group receiving sham vibration without actual vibration. Both groups will undergo 40 sessions over 8 weeks, with 5 sessions per week during hospitalization. The study includes various assessments such as the 10 meters Walk Test and 2 Minute Walk Test to measure walking speed, as well as evaluations of motor skills, muscle tone, autonomy, neuromuscular fatigue, and gait analysis. Throughout the study, participants will complete multiple tests and questionnaires including the Fugl-Meyer assessment, Modified Ashworth scale, ABILOCO questionnaire, Barthel index, electromyograms, and gait kinematics analysis. Researchers will monitor gait speed primarily at 2 months and collect data on muscle strength, fatigue, and functional autonomy. The total participation lasts for the 8-week intervention period with ongoing evaluations to assess recovery progress and safety.
