The use of footwear with contoured soles is common in treatment and care of patients with diabetes; these rocker sole shoes are designed to alleviate loading in key areas on the plantar surface of the foot, reducing pressure in key areas and alleviating pain, and potential soft tissue damage. While investigations of pressure changes have been conducted, no quantitative study to date has addressed the three-dimensional (3D) kinematic and kinetic changes that result from using these shoes. Forty subjects were tested wearing both unmodified and double rocker sole shoes, and the resulting motion patterns were compared to assess change caused by the rocker sole. Overall walking speed remained unchanged throughout testing; slightly increased flexion (<5 degrees ) was apparent at the hip, knee, and ankle during early and mid-stance. These results demonstrate the maintenance of gait function with minimal kinematic changes when using the rocker sole shoe. Investigations of multisegmental foot motion may reveal additional information about the contour effects; analysis of contour variations may also be warranted to investigate the possibility of controlling motion based on rocker sole parameters.
在糖尿病患者的治疗和护理中，使用带有成型鞋底的鞋具很常见；这些摇椅底鞋旨在减轻足底关键区域的负荷，降低关键区域的压力，缓解疼痛以及潜在的软组织损伤。虽然已经对压力变化进行了研究，但迄今为止，尚无定量研究探讨使用这些鞋子所导致的三维（3D）运动学和动力学变化。对40名受试者分别穿着未改良的鞋子和双摇椅底鞋进行测试，并比较由此产生的运动模式，以评估摇椅底引起的变化。在整个测试过程中，总体步行速度保持不变；在步态周期的早期和中期，髋、膝和踝关节处出现了轻微增加的屈曲（<5度）。这些结果表明，使用摇椅底鞋时，步态功能得以维持，且运动学变化最小。对多节段足部运动的研究可能会揭示有关鞋型效果的更多信息；对鞋型变化的分析也可能有必要，以研究基于摇椅底参数控制运动的可能性。
