- Public TitleEffectiveness of insoles in athletes with patellofemoral pain.
- Scientific TitleEffectiveness of custom made insoles in athletes with patellofemoral pain: A randomized controlled trial.
- ACRONYM
- hypothesisOur hypothesis is that custom made insoles and a home-based exercise program would be superior to a home-based exercise program alone at 12 weeks follow-up.
- Healt Condition(s) or Problem(s) studiedPatellofemoral pain syndrom, Insoles, Athletes
- Inclusion criteria1. Age 18-40 years;

- InterventionsThe patiŽnt will be randomly assigned to the treatment or placebo group. Both the treatment and the placebo group will receive a home exercise program. In addition the treatment group receives custom made insoles and the placebo group flat insoles. They will have to wear the custom made insoles daily.
- Primary outcomeThe participants fill in a (online) questionnaire before randomisation (baseline) and at 6 and 12 weeks after randomisation. The questionnaires contain questions regarding general pain and impairment, pain and impairment on general activities of daily living, during work/study activities and during sporting activities over the preceding week (10 point Likert scale), self reported recovery (6 point Likert scale) and the Kujala score.

- Brief summaryThis study had been designed after reviewing the literature on conservative therapy for patellofemoral pain syndrome in athletes. It was concluded despite the prevalence and the impact of PFPS is huge there is a lack of high quality research on the conservative management of PFPS in athletes. Insoles seem tot play an important role in the prevention and clinical management of PFPS in the general, but again this is not studied in athletes. Based on available literature our research group expects to discover effectiveness of insoles in athletes with patellofemoral pain in perceived recovery, pain severity, impairment and functional disability. This study is a randomized clinical trial where customised insoles and a home based exercise program is compared to flat insoles and a home based exercise program.
