퇴행성관절염 환자의 보행시 지면 반력 분석

Abstract

The purpose of this study is to analyze ground reaction force of walking for elderly women with degenerative osteoarthritis. The force platform (Kistler Type 9281CA,sampling frequency 1000HZ) was used to measure ground reaction force. Dependent variables for this study included both vertical and anterior / posterior ground reaction force components of walking.The paired t test was used to analyze the variables of the gait cycle for both the left and right side. The passive force peaks for elderly women with degenerative osteoarthritis had a greater magnitude and were greater in number than those of the control group. For the elderly group, active force peaks had a higher magnitude and were more frequent as well. The pattern of active force for the control group was symmetrical, while the pattern for the elderly group was asymmetrical. Compared to the control group, the stance time for elderly women was less. The total integral for the elderly group was less than that of the normal group.Braking time was less for elderly women in comparison to the control group. There were differences in the right and left leg for total impulse, braking time, and the impulse of braking force as well.
