초록

Fall is the most frequently occurred in the elderly. More importantly, this kind of fall occurs during activities of daily living(ADL). Therefore the purpose of this study was to develop of an evaluative protocols for the risk of falling in the elderly gait.
Total of 20 elderly participants, who have been lived in S city and have different level of fall history in recent year were recruited for this study. They were divided into to 4 groups depended on their fall history (GP1: no fall history, GP2: 1-5fall history, GP3: 6-10 fall history, GP4: 11-20 fall history in recent year).
To evaluate the risk of falling, medio-lateral COMX-COP inclination angles were computed.
After warmed-up and all reflective markers affixed to the body, each participant was performed 3 different walking(0%,30% & 50% leg length height obstacle). After all cameras were calibrated using the NLT(Nonlinear Transformation),participants' walking trials were recorded with 7 infrared camera(sampling rate: 100Hz) and their center of pressure(COP)during support phase were collected from 1 force plate(sampling rate:1000 Hz) embedded in the walkway.
Two-way(4 x 3) repeated measure analyses of variance(ANOVA) were performed to accomplish the study purpose. The Sidac simple effect test was used for the post-hoc analyses when significant factor effect and/or interaction were observed.
An alpha level of .05 was used as the criterion for the significance in all cases.
From this study, following results were found.
1) There was a significant height effect were found for all groups except GP1(p<.05).
2) There was a significant group effect were found between GP1 and the other groups(p<.05).
3) There was a significant group effect were found between GP2 and GP3, and GP4(p<.05), but no significant effect was found between GP2 and GP3(p>.05).
