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

Effect of Vibratory Tendon Stimulation on Muscle Fatigue in the Acute Post-stroke Phase : Vibramain1

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.

Inclusion Criteria:

• Age:18 to 85
• Acute stroke (less than 7 days)
• Paretic upper limb: 3 or 4 to the MRC score and able to obtain a value of at least 10 kilograms on the handgrip strength
• Able to sign a consent form
• Affiliated to a social insurance

Exclusion Criteria:

• Person under tutorship or curatorship,
• Sleepiness
• Pregnancy or breastfeeding woman
