Abstract

Background: Life-space mobility is defined as the spatial area traversed by an individual in daily life, extending from bedroom to locations beyond the individual's hometown, considering distance, frequency, and required assistance. The Life-Space Assessment (LSA) is used to evaluate life-space mobility. It has been reported that the LSA score after total hip arthroplasty (THA) shows an improvement relative to the preoperative score in patients with hip osteoarthritis. Symptoms and walking function also improve after THA. However, the association between these improvements and an increase in the LSA score after THA remains unclear. The purpose of this study was to identify the factors associated with an increase in the LSA score after THA in females with hip osteoarthritis.

Methods: This retrospective cohort study involved females planning to undergo primary and unilateral THA for hip osteoarthritis. The LSA score, subjective hip symptoms and function (assessed using the modified Harris hip score), and walking speed were assessed preoperatively and at 6 months postoperatively. Factors associated with the postoperative change in the LSA score were investigated using multiple regression analysis.

Results: A total of 120 participants were included. Improvement in walking speed (β = 0.19, P = 0.011) was significantly associated with the postoperative increase in the LSA score. The preoperative LSA score (β = -0.67, P < 0.001), age (β = -0.17, P = 0.011), and contralateral hip osteoarthritis (β = -0.15, P = 0.017) were also associated with the change in the LSA score.

Conclusions: The recovery of maximal walking speed, preoperative life-space mobility, age, and contralateral hip osteoarthritis influenced postoperative expansion of life-space mobility. Improved walking speed may serve as a key factor contributing to the expansion of life-space mobility following THA.

女性骨关节炎患者全髋关节置换术后生活空间活动的相关因素：一项单中心回顾性队列研究

背景：生活空间流动性被定义为个人在日常生活中所穿越的空间区域，从卧室延伸到个人家乡以外的地方，考虑到距离、频率和所需的帮助。LSA （Life-Space Assessment）用于评估生命空间的流动性。据报道，髋关节骨关节炎患者全髋关节置换术（THA）后的LSA评分相对于术前评分有所改善。THA术后症状和行走功能也有所改善。然而，这些改善与THA后LSA评分增加之间的关系尚不清楚。本研究的目的是确定女性髋关节骨关节炎患者THA后LSA评分升高的相关因素。方法：这项回顾性队列研究涉及计划接受原发性和单侧髋关节置换术治疗髋关节骨关节炎的女性。术前和术后6个月分别评估LSA评分、髋关节主观症状和功能（使用改良Harris髋关节评分进行评估）以及行走速度。采用多元回归分析探讨与术后LSA评分变化相关的因素。结果：共纳入受试者120人。行走速度的改善（β = 0.19, P = 0.011）与术后LSA评分的升高显著相关。术前LSA评分（β = -0.67, P < 0.001）、年龄（β = -0.17, P = 0.011）和对侧髋关节骨关节炎（β = -0.15, P = 0.017）也与LSA评分的变化有关。结论：最大步行速度的恢复、术前生活空间活动能力、年龄和对侧髋关节骨关节炎影响术后生活空间活动能力的扩大。步行速度的提高可能是髋关节置换术后生活空间流动性扩大的关键因素。
