초록

In this study, we performed motion analysis for ten subjects aobve 75 in order to analyze lower extremity joint movement patterns during upslope and downslope walking. Spatiotemporal parameters of walking, lower extremity joint movements on sagittal plane and ground reaciotn force were analyzed and the conclusions are as follows.
1. Cadency, walking velocity and stride length decreased during upslope and downslope walking compared to level walking. They showed significant differences at 10° inclination in upslope walking and at 5° inclination in downslope walking.
2. As for flexion/extension movement of lower extremity joint at HC event during gate cycle, thele fxion of knee and hip joint increased during upslope walking and dorsal flexion of ankle was large. Knee joint flexion at TO event decreased as the inclination of upslope walking increased, and it was significantly different compared to level walking.
3. As for anterior/posterior tilt of pelvis, it decreased during downslope walking and increased during upslope walking compared to level walking.
4. At ankle joint, the moments were different depending on thein clination of the ramps. At knee and hip joint, the maximum movements were different depending on the inclination of the ramps.
5. GFR in initial stance phase was higher in downslope walkingth an in upslope walking, and GFR in late stance phase was higher in upslope walking than in downslope walking.
