Q

Important steps to analyse movements

A
  1. Name the movement at the hip joint
  2. List the muscles acting as movers in this activity
  3. List the muscles acting as stabilisers
  4. For each of the muscles above, list all other actions they produce
  5. List muscles acting as synergists
49
Q

Factors contributing to MOBILITY at the hip joint

A
  • Acetabular labrum: provides increased surface area for femoral head
  • Ball and socket joint (multi-axial – three degrees of freedom)
50
Q

Factors contributing to STABILITY at the hip joint

A
  • 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
51
Q

Hip stabilisers

A

Gluteus medius

Deep external rotators

Gluteus minimus
