BACKGROUND
Several neuromuscular impairments may be observed in older patients with knee osteoarthritis (OA), increasing the risk of falling, which is common during transfer activities. The Lie-to-Sit-to- Stand-to-Walk Transfer (LSSWT) test was developed to evaluate complex transfer abilities. The study aims to investigate the reliability and validity of LSSWT in patients with knee OA.
METHODS
Twenty-nine patients with knee OA were included in this study. The LSSWT, Timed up and go test (TUG), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) were administered to the patients. Patients rested for at least an hour between the trials to avoid fatigue.
RESULTS
The LSSWT has excellent reliability and high validity in patients with knee OA. The relative (ICC coefficient) and absolute (SEM and SRD95) reliability values are 0.96 (95% CI: 0.91-0.98), 1.00, and 2,75, respectively. The Pearson correlation coefficient of the LSSWT with the TUG is 0.73 ( < 0.01), and the Spearmen correlation coefficient of the LSSWT with the WOMAC is 0.54 ( < 0.05).
CONCLUSIONS
The LSSWT is highly reliable and valid in knee OA and is recommended for routine dynamic balance establishment. Having a low minimal clinically important difference shows the LSSWT's sensitivity. The LSSWT can easily identify dynamic balance deficits in knee OA patients and help prevent fall incidents.
背景
在老年膝骨关节炎（OA）患者中可能观察到几种神经肌肉功能障碍，这增加了跌倒风险，而跌倒在转移活动中很常见。为评估复杂的转移能力而开发了从躺到坐再到站再到行走的转移（LSSWT）测试。本研究旨在调查LSSWT在膝OA患者中的可靠性和有效性。
方法
本研究纳入了29例膝OA患者。对患者进行了LSSWT、计时起立行走测试（TUG）和西安大略和麦克马斯特大学骨关节炎指数（WOMAC）评估。患者在两次试验之间休息至少一小时以避免疲劳。
结果
LSSWT在膝OA患者中具有出色的可靠性和高有效性。相对（ICC系数）和绝对（SEM和SRD95）可靠性值分别为0.96（95%CI：0.91 - 0.98）、1.00和2.75。LSSWT与TUG的Pearson相关系数为0.73（<0.01），LSSWT与WOMAC 的Spearmen相关系数为0.54（<0.05）。
结论
LSSWT在膝OA中具有高度可靠性和有效性，推荐用于常规动态平衡评估。其最小临床重要差异较低，显示了LSSWT的敏感性。LSSWT可以轻松识别膝OA患者的动态平衡缺陷并有助于预防跌倒事件。
