Using Polgon goniometer, the time ratio between stride and height, and the maximal, angle of knee and hip joint angles in gait cycle were observed in 10 normal Korean man. And in a few groups of patients who have gait diturbances, the gait pattern was noted and compared.
The results were following;
1) The ratio between stride and height in normal subjects was 60.6% in average stride, 54.3% in short stride, 71.8% in long stride.
2) The time during I gait cycle was 1.47 sec, in average speed walking, 1.68 sec. in slow speed walking, 1. 25 sec. in fast speed walking.
3) The maximal flexion and extension of hip & knee joint angle in average stride and slow speed walking was 32.4´, 11.6´, 51.5´, -2.1´ each.
4) The smaller the stride, the maximal flexion & extension of hip joint was reduced and the maximal flexion of the knee joint was relatively unchanged but the maximal extension was reduced compared with average speed.
5) The angle-angle diagram seems to be a useful objective criteria in gait analysis in patients who have gait disturbances.
