Important steps to analyse movements
- Name the movement at the hip joint
- List the muscles acting as movers in this activity
- List the muscles acting as stabilisers
- For each of the muscles above, list all other actions they produce
- List muscles acting as synergists
Factors contributing to MOBILITY at the hip joint
- Acetabular labrum: provides increased surface area for femoral head
- Ball and socket joint (multi-axial – three degrees of freedom)
Factors contributing to STABILITY at the hip joint
- Articular fit (reasonable congruency)
- Acetabular labrum (deepens the socket and increases congruency)
- Strong capsule, reinforced by capsular ligaments
- Angle of inclination (increases contact area)
- Muscles
Hip stabilisers
Gluteus medius
Deep external rotators
Gluteus minimus
Pectineus
