Time Analysis of the Laterality of Gait in Healthy Adults

Abstract

The subjects were 36 healthy adults: 72 legs, 18 males and 18 females. All the subjects were right-foot dominant in kicking a ball. [Methods] Gait phase times were measured using pressure sensors. The time of one gait cycle was measured from heel strike to heel strike (HS) of the same side, the stance phase from HS to toe off (TO), stance phase I from HS to hallux contact (HC), stance phase II from HC to heel off (HO), and stance phase III from HO to TO. [Results] Significant differences were found between the left and right sides in stance phases II and III expressed as a proportion of one gait cycle. [Conclusion] Differences in the work performed by the legs are the cause of leftright differences in the gait of healthy adults.

The Ankle Energetic Effect of Functional Insoles on Walking

“…It has been reported that regarding the left-right difference in movement of the lower limbs of healthy individuals, movement is symmetrical while walking on a treadmill, with the left-right difference decreasing with increased speed among individuals suffering from vertical displacement of the knee 9) . Regarding left-right differences in the percentage of time standing on each foot during one walking cycle, it has also been reported that the time standing on the non-dominant leg was signi cantly longer than that on the dominant leg during the standing phase III (from heel landing to toe rising) 10) . In other words, it appears that left-right differences exist in the movement of the lower limbs during normal walking.…”

The Ankle Energetic Effect of Carbon Fiber Insoles on Walking

“…10 Regarding left-right differences in the percentage of time standing on each foot during one walking cycle, it has also been reported that the time standing on the non-dominant leg was significantly longer than that on the dominant leg during the standing phase III (from heel landing to toe rising). 11 In other words, it appears that left-right differences exist in the movement of the lower limbs during normal walking. From these reports, although a dynamic evaluation has been conducted on the balance of the lower limb movement, no evaluations into further details have been conducted.…”
