Dynamic Balance Analysis under Different Lower Extremities Tortuosity

Article Preview

Abstract:

The purpose of this study was to explore the balance of different condition of grounds through changing the inclines, and investigate the influence of lower extremities in different inclines. 20 healthy young males were taken as experimental participants. The Six-degree-of-freedom Motion Platform was taken to change the inclines to: -5°,0°,5°,10°. The Vicon three-dimension motion analysis system was utilized to capture the spatiotemporal parameters and the three-dimensional coordinates of lower extremities. On uphill, incline had no significant impact on balance. But tortuosity of hip and knee could significantly increase with the incline. On downhill, balance was significantly less than flat. Tortuosity of knee joint was significant larger than it on the flat ground. The mobility of hip and knee joint was large on uphill; the mobility of knee is large on downhill, but the balance was reduced. These could provide useful biomechanics information on clinical evaluation with dynamic balance. The result might have great significance to the lower extremities rehabilitation.
