Musculoskeletal system: complex movements Flashcards
1
Q
Early stance and heel strike - hip movement
A
- flexion but moving into extension
- agonists: gluteus maximus and hamstrings
2
Q
Early stance and heel strike - knee movement
A
- in extension (locked for stability) \
- stabilizers: quadriceps femoris, hamstrings and gastrocnemius
3
Q
Early stance and heel strike - ankle movement
A
- in dorsiflexion but moving into plantarflexion
- agonist: triceps surae
- antagonist: tibialis anterior
4
Q
Mid stance - hip movement
A
- continuing moving into extension
- agonist: gluteus maximus and hamstrings
5
Q
Mid stance - knee movement
A
- moving from extension into slight flexion
- agonist: hamstrings and gastrocnemius
6
Q
Mid stance - ankle movement
A
- continuing to move into plantarflexion
- agonist: triceps surae
7
Q
Late stance and toe off - hip movement
A
- in extension
- agonist: gluteus maximus and hamstrings
8
Q
Late stance and toe off - knee movement
A
- in extension due to body
- hamstrings and gastrocnemius is contracting (ready for next movement)
9
Q
Late stance and toe off - ankle movement
A
- in full plantarflexion
- agonist: triceps surae
10
Q
Early swing - hip movement
A
- in extension moving into flexion
- agonist: iliopsoas and rectus femoris
- antagonist: gluteus maximus and hamstrings
11
Q
Early swing - knee movement
A
- in flexion to lift foot of the ground
- agonist: hamstrings and gastrocnemius
12
Q
Early swing - ankle movement
A
- in dorsiflexion
- agonist: tibialis anterior
13
Q
Mid swing - hip movement
A
- in flexion
- agonist: iliopsoas and rectus femoris
- antagonist: gluteus maximus and hamstrings
14
Q
Mid swing - knee movement
A
- in flexion to lift foot of ground
- agonist: hamstrings and gastrocnemius
15
Q
Mid swing - ankle movement
A
- in dorsiflexion (clear toes)
- agonist: tibialis anterior
16
Q
Late swing - hip movement
A
- in flexion
- agonist: iliopsoas and rectus femoris
17
Q
Late swing - knee movement
A
- moving from flexion into extension (preparing for heel strike)
- agonist: quadriceps femoris
18
Q
Late swing - ankle movement
A
- in dorsiflexion
- agonist: tibialis anterior (pull into dorsiflexion)
- stabilizer: triceps surae to keep ankle stable
