Walking while lifting the knee above the normal height (knee-up walking) might improve and maintain muscular strength in the lower limbs, which is effective in the elderly to prevent falls. The purpose of this study is to investigate the effects of knee height during knee-up walking on walking pattern and its subjective usefulness. Twenty-two older subjects walked at their own pace in four different conditions of maximum knee height (H: thigh level to the ground, L: about 5cm above normal, M: between H and L, N: usual walking). The speed, step length, cadence, and form during walking were measured, and subjective mobility and exertion were assessed after walking. Walking speed and cadence were significantly lower in the H condition than other conditions, although there were no significant differences in the step length. In the H condition, awkward walking (swinging both arms and both legs in the same direction, or small swinging of the arms) and unstable walking were observed. Furthermore, the H condition showed significantly higher subjective difficulty and exertion than the others. In contrast, M and L conditions showed almost similar walking pattern and subjective usefulness as the N condition. In conclusion, these results suggest that the H condition involves a high risk of unstable standing and falling during walking, but M and L conditions can be safely performed in daily life in the elderly.
