The purpose of this study was to examine the effects on plantar pressure of the rocker bottom shoe, which is a frequently used intervention for the ulcerated diabetic foot. In-shoe pressure distribution was recorded during walking in a conventional extra-depth shoe which was then modified into a rocker bottom configuration with a 24 degrees rocker, and the experiment was repeated. Peak pressures in the rocker shoe were reduce by approximately 30% compared to the conventional shoe in the medial and central forefoot and in the toe regions, but pressures were elevated in the heel, the midfoot, and in the lateral forefoot regions. These experiments suggest that a correctly designed rocker bottom show may reduce the risk of ulceration in certain areas of the foot. However, since pressures in some regions can also be elevated by this type of footwear, attention to individual design is critical.
本研究的目的是检验摇椅底鞋对足底压力的影响，摇椅底鞋是糖尿病足溃疡常用的一种干预措施。在一双常规的超深鞋中行走时记录鞋内压力分布，然后将其改造成具有24度摇角的摇椅底结构，并重复该实验。与传统鞋相比，摇椅底鞋在内侧和中央前足以及脚趾区域的峰值压力降低了约30%，但在足跟、中足和外侧前足区域压力升高。这些实验表明，设计正确的摇椅底鞋可能会降低足部某些区域溃疡的风险。然而，由于这种类型的鞋类也会使某些区域的压力升高，因此关注个性化设计至关重要。
