Total knee arthroplasty (TKA) is the standard procedure for treating end-stage knee osteoarthritis. Nevertheless, some residual issues can persist, leading to various problems, including pain, compromised strength, impaired proprioception, postural instability, dynamic balance issues, and gait deficiencies. The Lie-to-Sit-to-Stand-to-Walk Transfer Test (LSSWT) implements a multi-faceted methodology to evaluate basic transfer abilities. The purpose of this study is to investigate the validity, reliability, and minimal clinically important difference of the LSSWT in TKA patients.
Twenty-two patients with TKA were enrolled in this study. The patients were administered the LSSWT, the Timed Up and Go Test (TUG), and the Hospital for Special Surgery (HSS) knee score. Patients rested between the tests for an hour to prevent fatigue.
The mean age was 68.1 ± 2.59 years and the mean HSS Knee Score was 85.43 ± 3.47 of the patients. The relative (ICC coefficient) and absolute (SEM and SRD95) reliability values were 0.88, 1.21, and 3.33 respectively. The Spearman correlation coefficient of the LSSWT with the TUG was 0.63.
The LSSWT displays excellent reliability and high validity in assessing fall risk, complex dynamic balance, and mobility required for daily activities in patients post-TKA. The low MCID value (3.33) indicates its sensitivity and ability to identify minor changes in a patient's status over time or in response to rehabilitation applications. Therefore, it is recommended to use the LSSWT when evaluating fall risk, dynamic balance, and mobility for community living, discharge planning, or facility admission.
全膝关节置换术（TKA）是治疗终末期膝骨关节炎的标准方法。然而，一些残余问题仍然存在，导致各种问题，包括疼痛、力量下降、本体感觉受损、姿势不稳定、动态平衡问题和步态缺陷。躺-坐-站-走转移测试（LSSWT）采用多方面的方法来评估基本的转移能力。本研究旨在探讨 LSSWT 在 TKA 患者中的有效性、可靠性和最小临床重要差异。
本研究纳入了 22 名 TKA 患者。患者接受了 LSSWT、计时起立行走测试（TUG）和美国特种外科医院（HSS）膝关节评分。患者在测试之间休息一个小时以防止疲劳。
患者的平均年龄为 68.1±2.59 岁，平均 HSS 膝关节评分为 85.43±3.47。相对（ICC 系数）和绝对（SEM 和 SRD95）可靠性值分别为 0.88、1.21 和 3.33。LSSWT 与 TUG 的 Spearman 相关系数为 0.63。
LSSWT 在评估 TKA 后患者的跌倒风险、复杂动态平衡和日常生活活动所需的移动性方面具有优异的可靠性和高度的有效性。低 MCID 值（3.33）表明其对患者状态随时间或对康复应用的微小变化的敏感性和识别能力。因此，建议在评估跌倒风险、动态平衡和社区生活、出院计划或设施入院的移动性时使用 LSSWT。
