Abstract

The effects of carried loads on human gait and the potential risk of slipping during walking up/down an inclined surface were studied using four normal subjects ascending and descending a 10 degree ramp three times with and without loads. Gait parameters, such as gait period, step length, swing phase scale, shank angle at heel contact and peak required coefficient of friction, were obtained using a gait analysis system. Statistical analyses of the results demonstrate that the peak required coefficient of friction does not increase but decreases when carrying loads that the subjects automatically change their gait parameters to avoid slipping and that differences in gait parameters among the subjects caused by personal walking habits and muscle strength result in different risks of slipping, even though they are in the same environment and with the same load.
