Effect of Vibratory Tendon Stimulation on Muscle Fatigue in the Acute Post-stroke Phase

"Grip strenght measurement will always be done in the same way : for each series, 3 measurements of maximum strength will be taken for each side. Participants will receive verbal encouragement.~After initial both sides grip strength evaluation, all participant will first experiment the vibration situation using the device Vibramoov Physio (TechnoConcept, Manosque, France): the vibrations had a frequency of 100Hz, with an amplitude of 2mm, they will be applied to the anterior part of the forearm for 10 minutes, 3 times. At the end of each 10 minutes vibration session, handgrip strength will be assessed.~* Participants then have a one-hour rest period.~* Control situation: participants will have 4 series of grip strength measurements every 10 minutes.~At the end of the 2 hours, the patient will be discharged from the study protocol."
