Study information

Primary study design	Interventional
Study design	Cluster randomised clinical trial
Secondary study design	Randomised controlled trial
Scientific title	Effect of a preventive exercise programme on the prevalence and intrinsic risk factors of anterior knee pain in volleyball players
Study objectives	Has a preventive exercise programme, designed as a result of systematic literature reviews, an effect on the prevalence and intrinsic risk factors of anterior knee pain in volleyball players?
Ethics approval(s)	Ethics approval received from the Commissie Medische Ethiek (O.G. 016), Reflectiegroep Biomedische Ethiek (Belgium) on the 25th May 2007 (ref: B.U.N. B14320071963).
Health condition(s) or problem(s) studied	Anterior knee pain disorders
Intervention	Control group: Normal training routine Intervention group: Normal training routine and exercise programme based on systematic literature reviews. The programme lasts four months and involves the following exercises: 1. Closed kinetic chain exercise for isometric strength 2. Open kinetic chain exercise for isometric strength 3. Eccentric exercise and plyometrics with emphasis on technique The intervention lasts four months, each month another accent: 1. 1st month: emphasis on closed kinetic chain exercise for isometric strength 2. 2nd month: emphasis on closed kinetic chain exercise for isometric strength 3. 3rd month: also eccentric exercise were included 4. 4th month: also plyometrics with attention of landing technique is added It is a progressive programme and includes strength exercises for vastus medialis (quadriceps), hamstrings, gluteus medius and adductors. It also includes stretching exercises of those muscle groups.
Intervention type	Other
Primary outcome measure(s)	Prevalence of anterior knee pain. All measures will be performed prior to and immediately after the intervention period for both the control and intervention groups.
Key secondary outcome measure(s)	1. Intrinsic risk factors: 1.1. Static and countermovement jump 1.2. Hip rotation asymmetry 1.3. Ankle dorsal flexion 1.4. Patellar mobility 2. Quadriceps flexibility 3. Hamstring flexibility All measures will be performed prior to and immediately after the intervention period for both the control and intervention groups.
