- InterventionsPatients receive six sessions of physical therapy with a one week interval. These sessions will consist of a standardized training progressing in difficulty and resistance over time. In between the physical therapy sessions the patients will be performing a home training program three times a week, which progresses in difficulty and resistance over time.
- Primary outcome• Running biomechanics of the knee and hip. Expressed in peak angles of external knee abduction, hip adduction and contralateral pelvicdrop measured with a motion capture system.
• Hip strength. Expressed in KG normalized to the patients’ body composition. Measured with a hand held dynamometer.
- Secondary outcomePain on a Visual Analogue Scale (VAS) in which 0 represents no pain, and 100 maximal pain:
• Directly after running, during measurement of running biomechanics
- Timepoints1. Intake measurement
2. Measurement after a six week training period
3. Follow-up measurement: ten weeks after initial intake

- Brief summaryRelevance: Patellofemoral pain is a common diagnose in young adults and adolescents. In running it is the most common knee injury, recorded up to 46%.

In despite of the high prevalence there is not much literature available regarding treatment on the topic. In a couple studies it has been shown that runners with PFP have changed running biomechanics and a strength deficit at the affected side. Currently there is evidence that a hip strengthening program reduces pain. Also there is evidence that gait retraining reduces pain. For the physical therapist it is important to understand what to expect from a particular intervention.

Objective: The aim of this study is to explore the effects of a functional training program for hip strengthening on running biomechanics.

Study design: A pre experimental design study with the number of at least n=13 subjects. An intake measurement will be followed by a six-week training program. A second measurement will take place after the six weeks of training. A follow-up measurement is planned four weeks after the second measurement.
