Exercise related lower limb injuries (ERLLI), are common in the recreational and competitive sporting population. Although ERLLI are thought to be multi-factorial in aetiology, one of the critical predisposing factors is known to gait abnormality. There is little published evidence comparing walking and running gait in the same subjects, and no evidence on the effect of gait velocity on calcaneal pronation, even though this may have implications for orthotic prescription and injury prevention. In this study, the walking and running gait of 50 physically active subjects was assessed using pressure plate analysis. The results show that rearfoot pronation occurs on foot contact in both running and walking gait, and that there is significantly more rearfoot pronation in walking gait (p<0.01). The difference in the magnitude of rearfoot pronation affected foot orthoses prescription. A 63% fall in computerized correction suggested by RSscan D3D software prescription was seen, based on running vs. walking gait. The findings of this study suggest that in the athletic population orthoses prescription should be based on dynamic assessment of running gait.
运动相关下肢损伤（ERLLI）在娱乐和竞技运动人群中很常见。虽然 ERLLI 的病因被认为是多因素的，但已知一个关键的诱发因素是步态异常。很少有文献证据比较同一受试者的步行和跑步步态，也没有关于步态速度对跟骨内旋影响的证据，尽管这可能对矫形器处方和预防损伤有影响。在这项研究中，使用压力板分析评估了 50 名身体活跃的受试者的步行和跑步步态。结果表明，在跑步和步行步态中，后足内旋都发生在足接触时，并且在步行步态中后足内旋明显更多（p<0.01）。后足内旋程度的差异影响足矫形器的处方。根据跑步与步行步态的比较，RSscan D3D 软件处方建议的计算机校正率下降了 63%。本研究的结果表明，在运动人群中，矫形器的处方应基于跑步步态的动态评估。
