The purpose of this study was to determine the effectiveness of two types of foot orthoses in controlling the magnitude and rate of internal tibial rotation, measured by the tibial pointer device, during walking. Ten subjects between the ages of 23 and 43 years volunteered to participate in the study. Prior to data collection, each subject was issued two types of foot orthoses: a pair of rigid, plastic orthoses with posting in either the forefoot or the rearfoot, and a pair of soft, accommodative, premolded orthoses with no posting. All subjects wore standardized footwear. Following a controlled break-in period for both footwear and orthoses, each subject was asked to walk at a self-selected speed over a 12-m walkway while the movement of internal tibial rotation was recorded with a video camera during five trials. The results indicated that both the rigid plastic and the accommodative foot orthoses significantly reduced the magnitude and the rate of internal tibial rotation. No significant difference was noted between the soft and rigid foot orthoses conditions.
本研究的目的是确定两种足部矫形器在控制步行过程中通过胫骨指针装置测量的胫骨内旋幅度和速率方面的有效性。10名年龄在23至43岁之间的受试者自愿参与该研究。在收集数据之前，为每个受试者发放了两种足部矫形器：一双在前足或后足有支撑的刚性塑料矫形器，以及一双无支撑的柔软、适应性预成型矫形器。所有受试者都穿着标准化的鞋类。在对鞋类和矫形器进行一段受控的磨合期后，要求每个受试者以自选速度在12米的走道上行走，同时在五次试验中用摄像机记录胫骨内旋的运动。结果表明，刚性塑料矫形器和适应性足部矫形器均显著降低了胫骨内旋的幅度和速率。柔软和刚性足部矫形器条件之间未发现显著差异。
