Document Summary

Stance time: 60% of gait cycle (gc) Initial double limb support time: 10% of gc. Single limb support time: 40% of gc. Terminal double limb support time: 10% of gc. Stride length- heel to heel distance in anterior-posterior direction between both initial contacts of same foot. Step length- heel to heel distance in anterior-posterior direction between the two feet. Ex: if left leg is leading leg, it is a left step length. Speed = cadence x step length (1/2 of stride length) Self-selected comfortable speed is approximately 2-3 mph but varies person to person. With running, no double-limb support period increased double-limb support period. Extension during stance phase, flexion during swing phase. Peak extension: terminal double limb support period. First 10% of gait cycle, not much motion. 1st and smaller peak at 15% of gait cycle. 1st valley at 40% of gait cycle or second half of terminal stance.
