项目摘要

The purpose of this study was to investigate the relationship between health related QoL and physical activity levels among patients undergoing total hip arthroplasty(THA). Questionnaires(the Oxford hip score, the SF-8 and EQ5D) were self-administered preoperatively, and after THA. Physical activities were measured by a small pedometer with a uni-axial accelerometer for ten days, to determine the number of steps(steps/ day) as well as the time spent in physical activity(minutes/ day). And 3D gait analysis was performed pre and post operatively. Improvements in physical activity levels were correlated with health-related QoL scores in Japanese THA patients, suggesting that physical activity levels play an important role in QoL in these patients. We aimed to investigate the factors influencing gait improvement in the patients who had undergone total hip arthroplasty. We performed gait analysis on 43 female patients with unilateral hip osteoarthritis. All the patients were analyzed before and at 2, 6, and 12 months after the surgery. There were significant reductions in spatiotemporal parameters in the patients with hip osteoarthritis compared with the control group. The mean values of the spatiotemporal parameters of the patients showed considerable improvement by 12 months after surgery ; however, they did not reach the same values as those observed in the healthy subjects. The stage of osteoarthritis and the changes in the leg-length discrepancies were the factors that most influenced gait improvement after total hip arthroplasty throughout the follow-up period.

本研究旨在探讨全髋关节置换术（THA）患者的健康相关生活质量与体力活动水平之间的关系。在术前和THA后自我评估量表（牛津髋关节评分、SF-8和EQ 5D）。通过具有单轴加速计的小型计步器测量身体活动10天，以确定步数（步/天）以及身体活动所花费的时间（分钟/天）。术前、术后进行三维步态分析。在日本THA患者中，体力活动水平的改善与健康相关的生活质量评分相关，表明体力活动水平在这些患者的生活质量中起重要作用。我们的目的是探讨影响全髋关节置换术后患者步态改善的因素。我们对43例单侧髋关节骨关节炎的女性患者进行了步态分析。所有患者均在术前和术后2、6和12个月进行分析。与对照组相比，髋关节骨关节炎患者的时空参数显著降低。术后12个月，患者的时空参数的平均值显示出相当大的改善;然而，它们没有达到与健康受试者相同的值。骨关节炎的分期和下肢长度差异的变化是影响全髋关节置换术后整个随访期间步态改善的最重要因素。
