The Role of Indination on Coordination of Walking Movement

The purpose of this study is to find out the role of inclination on the characteristics of coordination of walking movement. For the aim, a total of twelve female adults were selected and required to free-walk on a treadmill at normal speed(1.25m/sec). Four different angles were applied to the treadmill’s incline, i.e. 0%, 5%, 10% and -5%. Those female adults performed walking more than five time for each of the treadmill slope. The test was done using Vicon370 made by Oxford Metric Co. At least 3 sets of the test results, after excluding apparently abnormal figures, were standardized and analysed. In the analysis, the three-dimensional quantitative method was adopted. For the coordination factor analysis, correlation coefficient was checked to figure out coordination effect. From the above results, the following conclusion was drawn. 1. The effect of different inclination on coordination pattern was clearly revealed in flexion and extension of the sagittal plane, which showed large movements. 2. During walking, the degree of inclination affected the changing patterns of coordination in lower extremities.
