Patellofemoral Pain Syndrome
Behavioral: High exercise therapy
Behavioral: Low exercise therapy
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
|Official Title:||Dosage-dependence of Graded Exercise Therapy in Patients With Patellofemoral Pain Syndrome. A Randomized Controlled Clinical Trial.|
- Pain measured by a Visual analogue scale (VAS). [ Time Frame: 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.
- Function measured by a Step-down test and by a modified Functional Index Questionnaire (FIQ). [ Time Frame: Pre-test, post-test (at 3 months after completed intervention) and at one year follow-up. ]

Experimental: high exercise
High dose, high repetition exercise therapy, 3 times weekly in 12 weeks
|Behavioral: High exercise therapy|
Experimental: low exercise
low dose, low repetition exercise therapy, 3 times weekly in 12 weeks
|Behavioral: Low exercise therapy|
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.
