Gait Flashcards
What are the two major gaits?
Walking and running
Which phase of the walking gait cycle takes up 60%?
Stance phase
Which phase takes up 40% of the walking gait cycle?
Swing phase
Which steps make up the double support phase of the stance phase?
Initial contact (A), loading response (B) and pre-swing (E)
Which steps make up the single support phase of the stance phase?
Mild stance (C), terminal stance (D)
True or false: The swing phase only has single support phases
True
What are the steps of swing phase?
Initial swing (F), mid swing (G), terminal swing (H)
During the gait cycle, the lower limb muscles must _________ the body forward by generating _________ motions of the limb segments and __________ body weight that produce unwanted torques at some of the lower limb joints
Propel; angular; support
What is the largest joint motions in the sagittal plane?
Flexion/extension
What joint motions occur in the coronal plane?
Abduction/adduction
What joint motions occur in the transverse plane?
Medial/lateral rotation
What muscle groups are involved in the steps A and B?
Ankle dorsiflexors, hip extensors, knee extensors and plantarflexors
Which muscle groups are involved in steps C to E?
Plantarflexors, intrinsic foot muscles (plantar), hip flexors, ankle dorsiflexors
Which muscle groups are involved in steps F to H?
Hip flexors, knee flexors, ankle dorsiflexors, hip adductors
What role do hip abductors have in the stance phase?
Oppose hip adduction during single support phase
