- Externally rotates the hip[2]
- Assists in adduction of the hip[2]
- Stabilises the femur head in the acetabulum[1]
Clinical relevance[edit | edit source]
- Groin pain[3]
- Groin Strain[4]
- Muscle tear[5]
- Tendinitis[3]
- Ischiofemoral impingement[5][6]
Assessment[edit | edit source]
- Palpation
- Muscle length testing
- Muscle strength testing
- Functional tests.
Treatment[edit | edit source]
