Muscle Activity During Gait
- Discussion:
- during swing, the ankle dorsiflexes by the concentric contraction of
anterior tibialis muscle;
- all other muscles are silent;
- sub-talar joint assumes near neutral position, & toes dorsiflex slightly as foot prepares for next episode of
stance;
- once toe leaves the ground;
- contraction of the quadriceps, initiated before toe off, apprarently serves two purposes;
- it prevents heel from rising too high in a posterior direction;
- it helps to initiate the forward swing of the leg;
- during latter part of swing phase, slightly before heel strike:
- hamstrings muscles become active;
- function of the hamstring muscles at this time is to decelerate forward swing of leg and thereby control the position of the foot at heel strike;
