Quantification of Arm Non-Use After a Stroke

Reproducibility assessment of a quantitative measure of the amount of trunk compensation by kinematic analysis in a grasping task in stroke patients.This "maladaptive trunk compensation" is suspected to be underlined by "arm non-use" in some patients, since this abnormal movement impairs the ability of patients to correctly flex their shoulder and extend their elbow during grasping.

Inclusion Criteria: * · Patient hemiparetic * Hemiplegic Patient * Patient can perform a global task with the gripping limb Exclusion Criteria: * Patient can not actively tender elbow of the affected limb, * Patient who can not actively flex the shoulder of the affected limb, * Patient with a passive extension deficit elbow\> 30 °, * Patient with a shoulder flexion passive deficit\> 60 °, * Patient with severe neglect * Patient bearer severe cognitive impairment * A patient with aphasia understanding disorders
