The L test is a modified version of the timed up and go test (TUG), extending the walking distance from 6 to 20 meters and also requiring participants to make four turns in both (right/left) direction. It could be a useful measurement method in assessment of functional mobility for patients with Total Knee Arthroplasty (TKA). The aim of the study was to determine reliability, concurrent validity, and minimal detectable change (MDC) of L test in patients with TKA.
The study included 43 patients with TKA. The Intraclass Correlation Coefficient (ICC) was used to assess the intra-rater reliability of the L test. The correlations of the L test with TUG were assessed for concurrent validity.
Intra-rater (ICC 0.97) reliability of the L test was determined to be excellent. The SEM and MDC values of intra-rater reliability were 1.03 and 2.84, respectively. A high correlation was found between the L test and TUG (r: 0.75).
The L test is a valid and reliable method in the assessment of functional mobility in patients with TKA. The L test can be used to quantify changes in functional mobility level in patients with TKA.Implications for rehabilitationThe L test is a reliable and valid measurement tool that can be used to assess functional mobility in patients with TKA.Clinicians and researchers can use a greater change than 2.84 seconds for the L test as a meaningful change in patients with TKA.
L 测试是计时起立行走测试（TUG）的改良版本，将行走距离从 6 米延长至 20 米，并且还要求参与者在两个方向（左右）各进行四次转弯。它可能是评估全膝关节置换术（TKA）患者功能性移动能力的有用测量方法。本研究的目的是确定 TKA 患者 L 测试的可靠性、同时效度和最小可检测变化（MDC）。
本研究纳入了 43 名 TKA 患者。使用组内相关系数（ICC）评估 L 测试的内部观察者可靠性。为了评估同时效度，评估了 L 测试与 TUG 的相关性。
L 测试的内部观察者可靠性（ICC 0.97）被确定为优秀。内部观察者可靠性的 SEM 和 MDC 值分别为 1.03 和 2.84。L 测试与 TUG 之间存在高度相关性（r：0.75）。
L 测试是评估 TKA 患者功能性移动能力的有效且可靠的方法。L 测试可用于量化 TKA 患者功能性移动能力水平的变化。
L 测试是一种可靠且有效的测量工具，可用于评估 TKA 患者的功能性移动能力。对于 TKA 患者，L 测试的变化大于 2.84 秒可被视为有意义的变化。
