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.

本研究的目的是调查接受全髋关节置换术（THA）的患者健康相关的生活质量和体力活动水平之间的关系。术前和全髋关节置换术后自行进行问卷调查（牛津髋关节评分、SF-8 和 EQ5D）。通过带有单轴加速度计的小型计步器测量身体活动十天，以确定步数（步/天）以及身体活动所花费的时间（分钟/天）。术前和术后均进行 3D 步态分析。日本 THA 患者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发挥着重要作用。我们的目的是探讨影响全髋关节置换术患者步态改善的因素。我们对 43 名单侧髋骨关节炎女性患者进行了步态分析。所有患者在术前和术后 2、6 和 12 个月进行分析。与对照组相比，髋骨关节炎患者的时空参数显着降低。术后12个月，患者的时空参数平均值显示出显着改善；然而，他们并没有达到与健康受试者中观察到的相同值。骨关节炎的分期和腿长差异的变化是全髋关节置换术后整个随访期间对步态改善影响最大的因素。
