Muscle Activity During Gait
- Discussion:
- at initiation of double limb
stance, heel contacts ground, & ankle rapidly
plantar-flexes as
tibialis anterior eccentrically contracts;
- at moment of heel strike, during the first interval of stance phase, anterior tibial & extensor muscles of
toes are functioning maximally to prevent foot slap and decelerating the foot towards flat;
- as wt bearing acceptance proceeds, the internal rotation of tibia causes
subtalar &
mid tarsal joint eversion;
- calcaneocuboid joint is locked by the pronated position;
- forefoot supinatory twist converts foot to rigid construct;
- while this is occurring, the forefoot contacts the ground along the lateral border of the foot;
- fifth metatarsal head contact is followed either by medial contact to the first metatarsal
head followed by second and third heads;
