Primary Outcome Measures

Name	Time	Method
<p>Frequency Response Functions (FRF) describe the relation between the<br /><br>disturbances and the human responses (ankle and hip angle and corresponding<br /><br>joint torques) in means of amplitude and timing. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>A model is fit onto the experimentally derived FRF, to estimate parameters with<br /><br>a physiological meaning, for instance ankle and hip joint passive stiffness,<br /><br>reflexive properties and time delays. </p><br>
