Primary Outcome Measures

Name	Time	Method
<p>Balance task: The threshold rotational stiffness at which the patient<br /><br>successfully manages to keep the boards deviation below 2.5 degrees for 70% of<br /><br>the trial (RStiff2.5). Lower RStiff2.5 indicates better balance capacity.<br /><br><br /><br>Automaticity: Sample entropy and fluency (jerk) of balance board movements.<br /><br>Higher sample entropy indicates less regular and hence more automatic movement<br /><br>execution, while lower jerk values indicate more fluent and hence more<br /><br>automatic movements.<br /><br><br /><br>Cognitive dual-task performance (tone counting task): Accuracy (%) and reaction<br /><br>time (ms). To address a possible speed-accuracy trade-off, accuracy and<br /><br>reaction time are combined into a composite score: Performance = (Accuracy (%)<br /><br>/ Reaction Time (ms)) x 100%<br /><br><br /><br>Dual-task performance: Dual-task Costs (DTC) = (Dual-task performance -<br /><br>Single-task performance) / Single-task performance 100%</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Cognitive functioning: Neuropsychological test scores will be expressed in<br /><br>standardised scores (z-scores)<br /><br><br /><br>Tests of motor functioning, mobility, daily functioning/quality of life<br /><br>- Berg Balance Scale score (0-56)<br /><br>- Timed-up-and-Go score: time needed to complete test (in seconds)<br /><br>- Posturography: Amplitude of center-of-pressure (COP) & total path length of<br /><br>COP<br /><br>- 10 meter walk test: time needed to walk 10 meters (seconds)<br /><br>- FAC score (0-5)<br /><br>- USER<br /><br>- NSA (lower extremity: 0-80)<br /><br><br /><br>Movement-Specific Reinvestment Scale (MSRS; 10-60)<br /><br>- Patients' inclination to consciously control their movements with an internal<br /><br>focus (Conscious Motor Processing subscale; 5-30)<br /><br>- Degree to which patients feel self-conscious about/monitor their style of<br /><br>moving (Movement Self-Consciousness subscale; 5-30)</p><br>
