In this study nine different rigid rocker shoe designs were tested in 17 symptom-free male subjects and compared with the control condition of a flexible, non-rockered extra-depth shoe with the same flat insole. Effects of both rocker height and axis location were explored. Peak pressure was reduced at most forefoot locations by rocker shoes, but increased in the midfoot and heel. Axis location was found to have an important effect, particularly on hallux pressures. On average the best axis location for reducing metatarsal head (MTH) pressure was in the region of 55-60% of shoe length, while for the toes it was 65%. There was a mean trend towards optimal reduction of pressure in one of the rocker shoe conditions at each anatomical location, but the axis position for this optimal placement was variable across subjects and anatomical locations. While most configurations of the rocker shoes were superior to the control shoe, no single configuration was optimal for all subjects at all sites or even for all subjects at the same site. Therefore, some form of plantar pressure measurement in conjunction with gait training to ensure correct use of the rocker shoes would appear to be essential if the pressure reducing effect of the rigid rocker bottom shoe is to be optimized.
在本研究中，对九种不同的刚性摇椅式鞋垫设计在17名无症状男性受试者中进行了测试，并与具有相同平底鞋垫的柔性、非摇椅式加厚鞋垫的对照情况进行了比较。研究了摇椅高度和轴位置的影响。摇椅式鞋垫在大多数前足位置降低了峰值压力，但中足和足跟处的压力增加。发现轴位置有重要影响，特别是对拇趾压力。平均而言，降低跖骨头（MTH）压力的最佳轴位置在鞋垫长度的55%-60%区域，而对于脚趾则为65%。在每个解剖位置的一种摇椅式鞋垫条件下，存在压力最佳降低的平均趋势，但这种最佳放置的轴位置在不同受试者和解剖位置之间是可变的。虽然大多数摇椅式鞋垫配置优于对照鞋垫，但没有一种配置对所有受试者在所有部位都是最佳的，甚至对同一部位的所有受试者也不是最佳的。因此，如果要优化刚性摇椅底鞋垫的减压效果，某种形式的足底压力测量结合步态训练以确保正确使用摇椅式鞋垫似乎是必不可少的。
