This is an experimental, observational, prospective study designed to develop medical knowledge.

The primary objective of the study is to analyze the weight bearing of the hemiplegic side according to the different areas of interest during the practice of table tennis.

This study is part of a usual framework of management of post-stroke hemiplegic patients with an additional passage to the movement laboratory to collect additional data collection, via the use of force plateforms, considered here as non-interventional.

The passage to the movement laboratory consists in the practice of a table tennis session including three game situations. Before to the table tennis session, the subject placed on the force plateforms, performs a spontaneous bipodal station followed by a maximum voluntary support transfer on the hemiplegic limb. During the table tennis session, the subject is filmed and his load on the hemiplegic side during the game situations is evaluated using the force platforms.

In addition of the table tennis session three questionnaires are administered to the patient in order to know :

• The static and dynamic balance in order to identify persons at risk of falling: Berg Balance and Evaluation Scale
• The degree of autonomy of the patient: Modified Rankin Score
• The Stroke severity: NIHSS score

Inclusion Criteria:

• Patients treated at the Hopale Foundation for a stroke rehabilitation program
• Patients following the balance and coordination protocol - Minimum age of 18 years
• BERG score >40
• Subject has played table tennis at least once prior to the stroke.
• Patient is a member or beneficiary of a social security plan.
• Patient who has received informed information about the study and has given his/her consent
• Ability to understand French instructions.

Exclusion Criteria:

• Cognitive disorders notified in the medical file

• Subject under judicial protection :

  • Subject under guardianship
  • Subject under curatorship
  • Subject under protective measure

• Pregnant or breastfeeding woman

• Patient with cognitive disorders preventing the comprehension of instructions

The patients will be recruited among the patients included in the "balance and coordination" rehabilitation protocol at the Jacques Calvé center of the Hopale Foundation.
