Brief summary

The aim of the study is to assess the immediate effects of passive hip joint mobilisation (in comparison to a sham mobilisation) on eccentric hip abductor/external rotator muscle strength on the basis of manual muscle testing with a hand-held-dynamometer within a double-blinded cross-over study design. Patients with anterior knee pain and signs of impaired hip function will be recruited in Vienna and surrounding area, measurements/data collection will be conducted by two experienced physiotherapists in a physiotherapy group practice in 1150 Vienna.

Healthy volunteers

Inclusion criteria

* diagnosis: anterior knee pain * Prescription for physiotherapeutic treatment of anterior knee pain * signs of functional hip impairment: * impaired hip kinematics during single leg squat * reduced passive hip joint mobility in comparison to the other, unaffected side * manually weak tested hip abductors/external rota-tors in comparison to the other, unaffected side

Exclusion criteria

* intraarticular knee pathology * preceding trauma/operation of lower extremity on affected side * spinal disorders associated with low back pain, lumbar referred pain or nerve root irritation * severe and/or recurring ankle sprains in recent history (significant enough, that it required a period of immobilization) * other relevant comorbidities such as neurologic/rheumatologic/psychiatric diseases, osteoporosis and malign disorders * pregnancy
