Lower Extremeties Lecture 12 Flashcards
What are the locomotor movement functions of the LE?
-Limb supports body weight, other swings forward
Why is the sole of the foot important?
- Senses texture
- Friction properties of surface
What do OTs do with the LE?
- Transfers
- Bed mobility
- Dressing
- Positioning
- Splinting
- Balance
What role does the hip play?
-Support weight of HAT(head and trunk) in static and dynamic postures
Describe the capsule and ligaments of the hip
- Strong and dense
- Attached to entire periphery of acetabulum
- Covers entire femoral head: 1. thickest ant./sup. (most stress) 2. thinnest post/inf
Hip flexion
Knee flexed: hip flexion is 120-130
Knee extended: hip flexion is 90
Hip extension
Knee flexed: hip ext is decreased bc of rectus femoris
Knee extended: hip ext is 30
Typical gait pattern of hip
flexion: 30
hyperextension: 10
abb/adb: 5
med/lat rotation: 5
What position is the hip in during anterior pelvic tilt?
Hip flexion
What position is the hip in during posterior pelvic tilt?
Hip extension
What is hip hike?
Adduction of hip on side of hike
Abduction on opposite side of hike
What is pelvic drop?
Abduction of hip on side of drop
Adduction on opposite side
Explain pelvic rotation
- Forward rotation of pelvis: medial rotation of hip
- Backward rotation of pelvis: lateral rotation of hip
What are the functions of the hip flexors?
- Primary function: mobility mm to bring LE forward
- Secondary function: resist hip extension forces
What are the 4 primary hip flexors?
Iliopsoas(most important)
Rectus femoris(strongest when knee flexed)
Tensor fascia lata
Sartorius
