Overview
Brief Summary
Individuals with stroke may experience sensory-motor deficit and/or neglect, with possible reduction in motor imagery ability (MI). To our knowledge, no study completely investigated MI ability in one individual whereas MI practice can be performed using visual or kinesthetic modalities (respectively visualizing with mind's eyes or imagining movement using sensation) and internal or external perspectives (performing action as spectator or as actor). This study aims to investigate MI ability in patients with stroke as compared to aged-matched healthy individuals. The investigators will assess explicit MI ability using 3 questionnaires (Movement Imagery Questionnaire-RS - MIQ-RS, Kinesthetic and Visual Imagery Questionnaire-20 - KVIQ-20, Vividness of Movement Imagery Questionnaire-2 - VMIQ-2) and 2 tests (imagined Time Up and Go - iTUG, imagined Box and Block test - iBBT). Outcome parameters will be i) the composite score of vividness measured for all tests using Likert scales, ii) the temporal equivalence between MI and Physical practice (PP - where MI/PP ratio equal to 1 indicate good MI ability and respect of temporal equivalence between MI and PP) and iii) the amplitude of electrodermal activity. The investigators will also study implicit MI ability using a hand laterality judgment task. Outcomes parameters will be response time (i.e. the duration to identify the hand laterality) and the percentage of correct responses.

Outcomes
Primary Outcomes
Score of vividness
Time Frame: Day 1
Participants will self-report vividness that describe the success in imagining movements using a 5-points Likert scale (1=no image or no sensation to 5=image as clear as PP or sensation as intense as PP) for the KVIQ-20. The investigators will average the vividness for each items of the questionnaire.
Secondary Outcomes

- Amplitude of electrodermal responses that will be measured during imagined movement with reference to actual movements measured during VMIQ -2.(Day 1)
- Amplitude of electrodermal responses that will be measured during imagined movement with reference to actual movements measured during MIQ-RS.(Day 3)
- Score of vividness measured during iTUG.(Day 5)
- Temporal equivalence measured during iTUG.(Day 5)
- Score of vividness measured during MIQ-RS.(Day 3)
- Response time to identify the hand laterality during the implicit motor imagery ability assessment(Day 3)
