Recruitment & Eligibility
- Status
- Completed
- Sex
- Not specified
- Target Recruitment
- 40
- Unilateral brain damage caused by stroke or other type of acquired brain injury confirmed by neurological assessment and CT-scan or MRI-scan
- First measurement within 11 weeks after brain injury (recent patient group) or more than 1 year after injury (chronic patient group)
- Patient must be able to cooperate with neuropsychological assessment and the experimental task
- Patient must have hemiparesis as indicated by aberrant scores of on the Fugl-Meyer Assessment or Motricity Index
- Patient must be able to remain in seated position independently
- Patient's age is between 18 and 75 years.;Control group:;- Age-matched healthy adults
- Presence of progressive degenerative neurological disorder
- Presence of a severe language comprehension deficit (i.e., to the degree that the participant cannot understand the instructions)
- Inability to perform the leg movement task for one minute

- Primary Outcome Measures
Name Time Method <p>Motor task: the duration of one movement cycle (i.e., time needed for flexion<br /><br>and extension). Shorter duration represents better performance.<br /><br>Cognitive task<br /><br>1) Letter fluency task: The number of words named in one minute. The more<br /><br>words, the better the performance.<br /><br>2) Auditory recognition task: Number of correct responses & response time<br /><br><br /><br>Dual task performance is assessed by calculating dual task cost (DTC) with the<br /><br>following formula:<br /><br><br /><br>DTC = (dual task performance - baseline performance) / baseline performance x<br /><br>100%</p><br>
- Secondary Outcome Measures
Name Time Method <p>Automaticity of movement: The level of automaticity of movement will be<br /><br>measured with the jerk (derivative of the acceleration) of the lower leg.<br /><br>Higher jerk values represent a lower level of movement automatization.<br /><br><br /><br>Cognitive functioning: The neuropsychological tests will be transformed into<br /><br>demographically corrected standard scores. These scores will be averaged within<br /><br>each cognitive domain: attention, working memory, and executive functioning.<br /><br><br /><br>Motor functioning: Scores on the lower extremity items of the Fügl-Meyer<br /><br>assessment and Motricity Index<br /><br><br /><br>Reinvestment: Score on the Movement Specific Reinvestment Scale (MSRS).</p><br>
