Complex Movements Flashcards
1
Q
What is Quadrupedal Standing?
A
- Four bases of support
- Limbs active at many joints
- Demands energy
2
Q
What is bipedal standing?
A
- Relatively small area of contact with group
- Plantar surface of feet
- Energy efficient
3
Q
When we stand how does the hip act?
A
- Posterior to joint
- Joint pushed into extension
- Extension tightens joints: locked
4
Q
Capsular ligaments of hip joint
A
- Hip in flexion: loose anteriorly, tight posteriorly
- Hip in extension: tight anteriorly, loose posteriorly
5
Q
When we stand how does the knee act?
A
- Anterior to joint
- Joint pushed into extension
- Extension tightens joints: locked
6
Q
When we stand how does the ankle act?
A
- Anterior to joint
- ‘Fall’ into dorsiflexion
- Not locked
- Plantarflexors stabilise
- Energy consumed
7
Q
Gait cycle: Early stance - Hip
A
- In flexion moving into extension
- Concentric activity of glutes and hamstrings
8
Q
Gait cycle: Early stance - Knee
A
- In extension (locked for stability)
- Isometric activity of quadriceps femoris, hamstrings and gastrocnemius
9
Q
Gait cycle: Early stance - Ankle
A
- In dorsiflexion (stable) but moving into plantarflexion
- Concentric activity triceps surae and eccentric activity of tibialis anterior control rate of foot drop
10
Q
Gait cycle: Mid stance - Hip
A
- Moving into extension
- Concentric activity of glutes and hamstrings
11
Q
Gait cycle: Mid stance - Knee
A
- Moving from extension to slight flexion
- Concentric action of hamstring and gastrocnemius
12
Q
Gait cycle: Mid stance - Ankle
A
- Moving into plantarflexion
- Concentric action of triceps surae
13
Q
Gait cycle: Late stance - Hip
A
- In extension
- Concentric activity of glutes and hamstrings
14
Q
Gait cycle: Late stance - Knee
A
- In extension as ankle moves into full plantarflexion
- Concentric action of hamstrings and gastrocnemius
15
Q
Gait cycle: Late stance - Ankle
A
- In full plantarflexion
- Concentric action of triceps surae
