Foot progression angle adjustment was shown to reduce external knee adduction moment (EKAM) and knee adduction angular impulse (KAAI) during level ground walking. However, evidence on effects of foot progression angle adjustment on the above surrogate measures of medial knee loading during stair climbing is limited. Hence, this study examined the effects of toe-in and toe-out gait on EKAM and KAAI during stair ascent and descent. Kinematic and kinetic data were collected from thirty-two healthy adults during stair ascent and descent with toe-in, toe-out and natural gait. A repeated measures ANOVA indicated that toe-in gait significantly reduced the first EKAM peak (P < 0.001) and KAAI (P = 0.002), while toe-out gait significantly increased the first (P < 0.001) and second (P = 0.04) EKAM peaks and KAAI (P < 0.001) when compared with natural gait during stair ascent. During stair descent, toe-in gait significantly reduced the first (P < 0.001) and second (P = 0.032) EKAM peaks and KAAI (P < 0.001), whilst toe-out gait significantly increased the first EKAM peak (P = 0.022) and KAAI (P = 0.028) when compared with natural gait. In conclusion, toe-in gait was found to be a viable strategy in reducing medial knee loading during stair climbing.
