Primary Outcome Measures

Name	Time	Method
<p>The main outcome parameters are joint angle of ankle and knee, to assess the<br /><br>ankle and knee movement. In other words, the dorsiflexion and plantarflexion of<br /><br>the ankle and the flexion and extension of the knee.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secondary study parameters related to the gait analysis are spatiotemporal and<br /><br>kinematic parameters, ground reaction force and muscle activity. Next to these<br /><br>gait related parameters, the BORG rating scale will be administerd after each<br /><br>condition and questionnaires to evaluate the usability and experience of the<br /><br>patient. </p><br>
