The gait of patients with neurogenic intermittent claudication was analyzed before and after surgery using a ground reaction force plate.
To analyze the gait characteristics of patients with neurogenic intermittent claudication, to evaluate quantitatively their gait improvement after surgical treatment, and to examine the differences in gait characteristics and postoperative improvement among different types of neuropathy.
A number of reports have been published on the pathophysiology or treatment of neurogenic intermittent claudication. However, almost no detailed reports exist on the gait abnormalities associated with this condition.
The subjects were 60 lumbar canal stenosis patients with intermittent claudication who underwent surgery at the authors' hospital. A ground reaction force plate was used for the analysis, and factors related to time and distance (speed, stride, interval, and pitch) were analyzed, as well as factors related to the style of walking (symmetry, reappearance, smoothness, sway, rhythm, and impact).
Before surgery, there were abnormalities of various factors related to the style of walking soon after the patients began to walk. Gait analysis also showed that the pattern of gait abnormality and its improvement after surgery varied depending on the type of neuropathy.
Gait analysis permits objective and quantitative evaluation of the gait characteristics of patients with lumbar canal stenosis and is useful for evaluating responses to surgical treatment in these patients.
使用地面反作用力板分析神经源性间歇性跛行患者手术前后的步态。
分析神经源性间歇性跛行患者的步态特征，定量评估手术治疗后其步态改善情况，并研究不同类型神经病变患者的步态特征及术后改善情况的差异。
关于神经源性间歇性跛行的病理生理学或治疗已有多篇报道。然而，几乎没有关于与此病症相关的步态异常的详细报道。
研究对象为60例在作者所在医院接受手术的腰椎管狭窄伴间歇性跛行患者。使用地面反作用力板进行分析，分析与时间和距离相关的因素（速度、步幅、步间时间和步频），以及与行走方式相关的因素（对称性、再现性、流畅性、摆动、节奏和冲击力）。
术前，患者开始行走后不久，与行走方式相关的各种因素就存在异常。步态分析还表明，步态异常模式及其术后改善情况因神经病变类型而异。
步态分析可对腰椎管狭窄患者的步态特征进行客观定量评估，有助于评估这些患者对手术治疗的反应。
