项目摘要

The effects of heel elevation of shoes on an abnormal gait of Parkinson's disease patients were investigated by using the Gait Scan and the F Scan. These measurements provided several gait parameters including walking speed, step length, step width, cadence, and distribution of plantar pressure. Twenty-five total patients with Parkinson's disease (Hoehn and Yahr stage : III-IV) and 16 total age-matched health people participated in this study. Heel elevation was evaluated with blocks placed beneath the heel that simulated shoes at four different heel heights ; 0, 1.0, 1.5, 2.0 cm. The pathway of the center of pressure, COP pathway, increased at the conditions with heel elevation compared with that without heel elevation. In the age-matched control group, the COP pathway also increased at the conditions with heel elevation. Compared with the age-matched control subjects without any gait disturbances, the patients with Parkinson's disease showed shorter COP pathway at any types of heel elevation. Another effects of heel elevation on Parkinsonian gait included hastening cadence, and shortening transitional time between the two pressure peaks. Parkinson's disease patients appeared to be able to walk with a gait pattern similar to the normal subjects by heel elevation. The influence of heel elevation was obviously in the measurements of walking, and it contributed to the improvement of gait in the Parkinson's disease patients through additional heel elevation of 1.0-2.0cm. These findings suggest the necessity of a further clinical trial with a large-scale sample to establish clinical utility of shoe modification in the patients with Parkinson's disease.

用步态扫描和F扫描研究了鞋跟抬高对帕金森病患者异常步态的影响。这些测量提供了几个步态参数，包括行走速度、步长、步宽、节奏和足底压力分布。共有25名帕金森氏病患者(Hoehn和Yahr分期：III-IV)和16名年龄匹配的健康人参与了这项研究。鞋跟抬高通过放置在鞋跟下方的积木来评估，这些积木模拟了四种不同鞋跟高度：0、1.0、1.5、2.0厘米。与无足跟抬高相比，足跟抬高时压力中心的COP通路增加。在年龄匹配的对照组中，在足跟抬高的情况下，COP通路也增加。与没有任何步态障碍的年龄匹配的对照组相比，帕金森病患者在任何类型的脚跟抬高时都显示出更短的COP路径。脚跟抬高对帕金森患者步态的另一个影响包括加速节奏和缩短两个压力峰值之间的过渡时间。帕金森氏症患者通过脚跟抬高，似乎能够以类似于正常受试者的步态模式行走。足跟抬高对步行测量的影响明显，通过增加1.0~2.0 cm的足跟抬高，有助于改善帕金森病患者的步态。这些发现表明，有必要进行进一步的大规模样本临床试验，以确定改装鞋在帕金森氏病患者中的临床实用性。
