Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It seems that prolonged vibratory stimulation of the anterior forearm in healthy subjects leads to fatigue of the muscles concerned, with a reduction in their strength. The aim of this study is to evaluate the impact of vibratory tendon stimulation on grip force fatigue during the acute post-stroke phase.

The investigations will be carried out by a specialized physiotherapist from the neurology department.

The experiment consists of three successive phases:

* First : measurement of the maximum handgrip force before any vibratory stimulation and then after the three sessions of ten-minute vibration.
* Second : Rest period
* Third: control phase with measurement of the maximum grip force every ten minutes without vibration.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vibration group

Patients with acute stroke less than 7 days with only one paretic upper limb will be assessed for eligibility.

Patient will undergo 8 grip strength evaluation and 30 minutes of forehand muscles vibration.

Group Type EXPERIMENTAL

Vibration

Intervention Type DEVICE

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.
