The purpose of the present paper is to investigate the walking pattern of patients with hip disorders. The materials consist of 37 cases of osteoarthritis, ten cases of fused hips and two cases of congenital hip dislocation which had not been treated. Of the 37 cases with osteoarthritis, seven cases were in pre-arthrosis or in the early stage of it. They had slight hip pain and an almost normal range of motion. Thirty cases were in advanced arthrosis and were treated by total hip replacement. For the purpose of examining the walking pattern of the above mentioned patients, three-dimensional components of the floor reaction force were measured by Matake's force plate, and three loop diagrams were made by taking two dimensions at a time and plotting them on an X-Y recorder in order to easily understand the walking as a pattern. In the present paper only the alpha-diagram, which is composed of the vertical, forward and backward components, was used. In the patients with osteoarthritis, the figure of the alpha-diagram decreases and the unweighting effect in the vertical floor reaction disappears as the degree of the hip pain increases, while, on the normal side, some compensatory function was seen in the characteristic figure. In the cases of untreated congenital hip dislocation, the figures of the alpha-diagram were similar to the pattern of a painful hip with osteoarthritis. From these facts it is concluded that the most important factor influencing the walking pattern is hip pain.
本文的目的是研究髋部疾病患者的行走模式。材料包括37例骨关节炎患者、10例髋关节融合患者和2例未经治疗的先天性髋关节脱位患者。在37例骨关节炎患者中，7例处于关节病前期或早期。他们有轻微的髋部疼痛，活动范围几乎正常。30例处于晚期关节病，接受了全髋关节置换术。为了检查上述患者的行走模式，通过Matake测力板测量地面反作用力的三维分量，并通过一次取两个维度并将其绘制在X-Y记录仪上制作三个环图，以便更容易地将行走理解为一种模式。在本文中，仅使用了由垂直、向前和向后分量组成的α图。在骨关节炎患者中，随着髋部疼痛程度的增加，α图的形状减小，地面垂直反作用力中的失重效应消失，而在正常侧，在特征形状中观察到一些代偿功能。在未经治疗的先天性髋关节脱位病例中，α图的形状与患有骨关节炎的疼痛髋部的模式相似。从这些事实可以得出结论，影响行走模式的最重要因素是髋部疼痛。
