Primary Outcome Measures

Name	Time	Method
<p>The primary outcome is the difference in the maximal dorsoflexion angle of the<br /><br>ankle when performing the weight bearing dorsoflexion lunge test between<br /><br>patients with a chronic midportion Achilles tendinopathy and healthy controls. </p><br>

Secondary Outcome Measures
