Brief summary
With this study two different therapeutic exercise regimens will be compared in patients with anterior knee pain (patellofemoral pain syndrome, PFPS).
Detailed description
Exercise therapy is widely used in the conservative treatment of patellofemoral pain syndrome (PFPS), but there is still no consensus on recommending any specific rehabilitation program. This study evaluates two different therapeutic exercise regimens in patients with PFPS and their effect on pain at rest and function. Supervised exercise therapy will be applied in both groups three times a week over a 3-month period with individually tailored and graded exercise programs, differing between groups in terms of number of exercises, number of repetitions and sets, and time spent on performing aerobic exercises.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain measured by a Visual analogue scale (VAS). | Pre-test, post-test (after completed intervention at 3 months) and one year follow-up. | This scale was illustrated with a 100 mm horizontal line with descriptors no pain at the 0 mm mark and worst pain imaginable anchoring the 100 mm. Participants were required to place a vertical mark on the horizontal line, representing their average level of pain experienced during the last 24 hours. This was done at rest and provided an illustration of the perceived pain severity, rated in millimetres. |
Secondary
| Measure | Time frame |
|---|---|
| Function measured by a Step-down test and by a modified Functional Index Questionnaire (FIQ). | Pre-test, post-test (at 3 months after completed intervention) and at one year follow-up. |
