Primary Outcome Measures

Name	Time	Method
<p>The primary outcome measure is the validated dutch version of the Victorian<br /><br>Institute of Sports Assessment- Patellar (NL-VISA-P) questionnaire (Zwerver et<br /><br>al, 2009), which quantifies the pain and activity level. The NL-VISA-P score<br /><br>ranged from 0 to 100, where 0 denotes no activity and maximum pain and 100<br /><br>denotes maximum activity and no pain. This is a validated questionnaire,<br /><br>specifically designed for evaluating outcome in Patellar tendinopathy. When<br /><br>there is pain in both knees the score for the most painful side is registered.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>VAS (Visual Analogue scale for pain) at three functional tests: patient gives a<br /><br>number on a scale from 0-10 whereas 0= no pain and 10= terrible pain. We take<br /><br>this score after 10 times on a declineboard of 25 degrees, the triple hop test<br /><br>and the maximal jump test (Zwerver 2010)<br /><br><br /><br>Furthermore a log that keeps track of the degree of pain (VAS) after every<br /><br>training / match and the degree of pain the morning after exercise is filled<br /><br>out. </p><br>
