The rocker sole is the most commonly prescribed external shoe modification. Use of rocker soles has been based on theoretical considerations and empirical observations with minimal scientific study and validation. With the passage of the therapeutic shoe bill (PL-100- 203sec4072) authorizing Medicare coverage of shoes and shoe modifications for diabetics, it is important to have objective data regarding the effect of rocker soles. The purpose of this proposed research is to study the effect of rocker soles on plantar pressures and gait. Our overall concern is that rocker soles not only affect plantar pressures but also produce kinetic and kinematic suprasegmental changes. The recently completed pilot studies support our hypotheses that plantar pressures and suprasegmental kinetics/kinematics are altered uniquely by each type of rocker and differ from baseline shoes. Our objective is to analyze how the different rocker soles redistribute plantar and suprasegmental forces and affect the timing of these forces. In order to achieve the study objectives, the following specific aims will be accomplished: 1. We will quantitate the effect of toe only rocker, negative heel rocker, and double rocker on plantar pressures. 2. We will determine the effect of toe only rocker, negative heel rocker, and double rocker on gait kinematics and kinetics. Our goals include analyzing whether negative heel rockers unload the forefoot and increase heel loading more than toe only rockers and whether this is accompanied by suprasegmental kinematic/kinetic gait changes. We would also like to determine if double rockers and forefoot rockers unload the forefoot equally but with less increase in heel loading (with the double rocker). We will compare the kinematic/kinetic suprasegmental effects of the toe only rocker, negative heel rocker, and double rocker shoes. We will study 40 sensate and 6 insensate subjects. The practical rehabilitation implication of this study is that a more quantitative understanding of the effects of different rocker shoes will allow scientifically based pedorthotic prescription.

摇杆鞋底是最常见的规定外鞋 改性 摇杆鞋底的使用一直是基于理论 考虑因素和经验观察， 研究 和验证。 随着治疗鞋法案的通过 （PL-100- 203 sec 4072）授权鞋子和鞋子的医疗保险范围 修改 对于糖尿病患者，重要的是要有关于 摇杆鞋底的效果。 这项研究的目的是研究 摇杆 足底压力和步态的鞋底。 我们的总体关切是， 摇杆 鞋底不仅影响足底压力， 和 运动性超节段变化。 最近完成的飞行员 研究 支持我们的假设，足底压力和超节段 动力学/运动学由每种类型的摇杆独特地改变， 与基准鞋不同。 我们的目标是分析不同的摇杆鞋底 重新分配 足底和超节的力量，并影响这些时间 力. 为了达到研究目的，以下具体 旨在 将实现： 1.我们将量化的影响，脚趾只有摇杆，负脚跟 摇杆和双摇杆的足底压力。 2.我们将确定的影响，脚趾只有摇杆，负脚跟 摇杆， 双摇杆对步态运动学和动力学的影响。 我们的目标包括分析是否负脚跟摇杆卸载 的 前脚和增加脚跟负荷超过脚趾只有摇杆和 是否 这伴随着超分段运动/动力步态 变化 我们 我也想确定是否双摇杆和前脚摇杆 前足平均卸载，但脚跟负荷增加较少 （与 双摇杆）。 我们将比较运动学/动力学 超切分 只有脚趾摇杆，负脚跟摇杆，和双 摇杆 鞋 我们将研究40名有感觉者和6名无感觉者。 这项研究的实际康复意义是， 更 定量了解不同的摇杆鞋的效果 将 允许基于科学的儿童矫正处方。
