Study Details

Study Description

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.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Hip Joint Mobilization passive accessory movement on femur in anterior/posterior direction, grade III for four minutes and passive physiological movement of the most restricted hip joint movement, grade III for one minute (without pain), and a verbal education of hypothesized underlying effect mechanisms.	Other: Joint Mobilization Manual Therapy Intervention, commonly used by physiotherapists
Sham Comparator: Laying on of Hands grade I, very small amplitude without encountering any tissue resistance for five minutes, thus effectively a Laying on of Hands, with a verbal education of hypothesized underlying effect mechanisms.	Other: Laying on of Hands Sham Hip Joint Mobilization

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years to 60 Years

Sexes Eligible for Study:

All

Accepts 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
