Heel lifts have been widely used as a conservative treatment for some musculoskeletal problems and complaints. However, the heel rise caused by heel lifts may also affect the plantar pressure distribution and stability during walking. This study aimed to test whether adding an arch support to a heel lift would improve its stability and comfort through comparing the center of pressure (COP) during walking and subjective ratings between heel lifts with and without an arch support. Fifteen healthy male participants were asked to walk along an 8m walkway while wearing high-cut footwear with the control heel lifts and the heel lifts with an arch support. A Footscan pressure plate was used to measure the COP during walking. Subjective ratings including medial-lateral control, dynamic foot/shoe fitting and overall comfort were assessed for each participant. The results showed that compared to the control condition, the COP trajectory was medially shifted during stance phase of gait in the arch support condition. The maximum displacements and velocity of medial-lateral COP in the forefoot contact phase were smaller in the arch support condition than in the control condition. Adding an arch support to a heel lift also significantly improved the subjective ratings in terms of the medial-lateral control, dynamic foot/shoe fitting and overall comfort. The findings of this study suggest that adding an arch support to a heel lift could improve its stability and comfort during walking.
足跟垫已被广泛用作某些肌肉骨骼问题和病症的保守治疗方法。然而，足跟垫引起的足跟抬高也可能影响步行过程中的足底压力分布和稳定性。本研究旨在通过比较有无足弓支撑的足跟垫在步行过程中的压力中心（COP）和主观评分，测试在足跟垫上添加足弓支撑是否会提高其稳定性和舒适度。15名健康男性参与者被要求穿着配备对照足跟垫和带足弓支撑足跟垫的高帮鞋沿着一条8米长的通道行走。使用Footscan压力板测量步行过程中的COP。对每位参与者评估包括内外侧控制、动态足部/鞋子贴合度和整体舒适度在内的主观评分。结果表明，与对照条件相比，在足弓支撑条件下，步态站立期的COP轨迹向内侧偏移。在前足接触阶段，足弓支撑条件下内外侧COP的最大位移和速度均小于对照条件。在足跟垫上添加足弓支撑在内外侧控制、动态足部/鞋子贴合度和整体舒适度方面也显著提高了主观评分。本研究结果表明，在足跟垫上添加足弓支撑可提高其步行过程中的稳定性和舒适度。
