Gait Flashcards
1
Q
Key phases of the gait cycle for 1 leg
A
- Initial contact
- Stance phase
- Swing phase
2
Q
Stride vs step
A
- Stride = initial contact to initial contact (same foot)
- Step = contact of one foot to contact of other (half a stride)
3
Q
Different double limb stances of the gait cycle
A
- Initial double limb stance
- Terminal double limb stance (after 1 step)
- Double limb stance (after 1 stride)
4
Q
Functions of the stance phase
A
- Shock absorption
- Stability
- Propulsion
5
Q
Functions of the swing phase
A
- Ground clearance
- Step length
6
