摘要
背景/目的:下肢肌肉功能传统上是通过5次坐立测试(5STS)和30秒椅子站立测试(30CS)等测试来评估的。ADR编码器是一个线性传感器,在坐立测试期间测量功率和速度。本研究旨在验证其作为老年人肌肉功能指标的用途。方法:对114名参与者(平均年龄:72.92±4.97岁)进行横断面研究。使用ADR编码器测量5STS、30CS、功率和速度。根据虚弱量表,参与者被分为虚弱、虚弱前和健壮组。评估了标准效度、观察者内效度和观察者间效度。结果:强相关性(r > 0.7;p < 0.001),功率、速度与5STS和30CS之间均存在差异。速度的观察者间类内相关系数(ICC)为0.90,观察者内相关系数为0.85。对于权力,观察者间的ICC为0.88,观察者内的ICC为0.79,均具有统计学意义(p < 0.001)。功率差异显著(7.78 W vs. 11.26 W;P < 0.001)和速度(0.40 m/s vs. 0.58 m/s;P < 0.001)。结论:ADR编码器是一种有效、可靠的测量老年人力量和速度的工具。它与5STS和30CS的强相关性证明了其临床相关性,具有跨观察者和时间点的高可重复性。它在不同的临床和社区设置的应用可以扩大其在老年功能评估的效用。
Reliability and Validity of the Linear Transducer "ADR Encoder" for Measuring Power and Speed of the Sit-to-Stand Tests in Older Adults.
Background/Objectives: Lower-limb muscle function is traditionally assessed with tests like the five times sit-to-stand test (5STS) and the 30-s chair stand test (30CS). The ADR Encoder, a linear transducer, measures power and velocity during the sit-to-stand test. This study aimed to validate its use as functional indicators of muscle function in older adults. Methods: A cross-sectional study with 114 participants (mean age: 72.92 ± 4.97 years) was conducted. The 5STS, 30CS, power, and speed were measured using the ADR Encoder. Participants were categorized into frail, pre-frail, and robust groups according to the FRAIL Scale. Criterion, intraobserver, and interobserver validity were assessed. Results: Strong correlations (r > 0.7; p < 0.001) were found between power, speed, and both 5STS and 30CS. The interobserver intraclass correlation coefficient (ICC) for speed was 0.90 and the intraobserver ICC was 0.85. For power, the interobserver ICC was 0.88 and the intraobserver ICC was 0.79, all statistically significant (p < 0.001). Significant differences in power (7.78 W vs. 11.26 W; p < 0.001) and speed (0.40 m/s vs. 0.58 m/s; p < 0.001) were observed between frail and non-frail participants. Conclusions: The ADR Encoder is a valid, reliable tool for measuring power and speed in older adults. Its strong correlations with the 5STS and 30CS demonstrate its clinical relevance, with high reproducibility across observers and time points. Its application in diverse clinical and community settings could broaden its utility in geriatric functional assessment.
