Measurements of Displacement Amplitude and Angular Velocities During Passive Extension of the Wrist and Hand Complex in Stroke Patients

Measurements of Displacement Amplitude and Angular Velocities During Passive Extension of the Wrist and Hand Complex in Stroke Patients

The main objective of this monocentric prospective study is to evaluate the amplitudes and angular velocities of extension of the hand and wrist joints during passive mobilization by a physiotherapist in healthy subjects and stroke patients with spastic hands.

Secondary objectives:

• To compare amplitude and angular velocity values between the group of stroke patients and the group of healthy volunteers,
• To compare amplitude and angular velocity values according to the two types of mobilization (i,e, thumb or fifth finger),
• To assess pain due to mobilization in stroke patients.

Conduct of research:

The realization of the measures will take place at the GHRMSA rehabilitation department.

After receiving the written consent of the study participant, the physiotherapist will proceed with the passive mobilization of the spastic hand of the stroke patient or the dominant hand for healthy volunteers. Videos of the hand will be made using the Darfish system which will allow analysis of the primary endpoint.

Two mobilizations will be performed for each participant, i.e. one for each type of medial or lateral grip. The order of mobilization will be determined by randomization.
