Conditions
Interventions
The experimental intervention is the manipulation of attentional focus.
Participants will be instructed to focus on alternately placing their foot in

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