Describe bipedal standing |
- relatively small area of contact - energy efficient |
|
|
Describe the position of gravity during bipedal standing. |
Hip: - posterior to the joint - extension Knee: - - extension Ankle: - anterior to the joint - dorsiflexion - plantar flexors on the posterior side of the ankle counteract the dorsiflexion -requires energy |
|
|
Early stance: initial contact |
Hip: flexion - ilipsoas Knee: Extension - quadriceps femori Ankle: dorsiflexion - tibialis anterior concentric; agonist |
|
|
Mid stance |
Hip: anatomical position - quadriceps = concentric; agonist Knee: extension - quadriceps = isometric; stabiliser Ankle: anatomical position -tibialis anterior = eccentric; antagonist -gravity = cconcentric; agonist |
|
|
Late stance |
Hip: extension - gluteus maximus Knee: flexion - hamstring Ankle: plantar flexion - triceps surae concentric; agonist |
|
|
Early swing |
Hip: slight flexion -ilipsoas Knee: flexion - hamstring Ankle: Dorsiflexion - tibialis anterior concentric; agonist |
|
|
Mid swing |
Hip: flexion - illpsoas = concentric; agonist Knee: momentum - mimics pendulum Ankle: dorsiflexion - tibialis anterior = isometric; stabiliser |
|
|
Late swing |
Hip: flexion - ilipsoas = concentric; agonist Knee: fully extended - quadriceps = concentric; agonist Ankle: dorsiflexion - tibialis anterior = isometric; stabiliser |
