Abstract

Objective: The accuracy of determining gait independence using adductor pollicis muscle thickness (APMT) and skeletal muscle mass index (SMI) in community-dwelling older adults undergoing outpatient rehabilitation remains unclear. The purpose of this study was to compare the accuracy of determining gait independence using APMT and SMI in community-dwelling older adults undergoing outpatient rehabilitation.

Methods: This study included 98 older adults (mean age: 85.2 years). Participants received outpatient rehabilitation one to three times a week. The main outcomes were gait independence (functional independence measure gait score: 6 or 7), skeletal muscle mass index (SMI), and APMT. Receiver operating characteristic (ROC) curves of APMT and SMI for gait independence were created, and cut-off values were calculated using the Youden index. Additionally, the area under the curve (AUC) s of the APMT model and the SMI model were compared using the Delong test.

Results: Among the 98 participants (male; 19, female; 79), 53 (54.1%) were in the gait independent group. The cut-off value of APMT calculated from the ROC curve was 13 mm; the sensitivity and specificity were 67.9% and 86.7%, respectively; and the AUC was 0.800. The cut-off value of SMI calculated from the ROC curve was 4.6 kg/m²; the sensitivity and specificity were 90.6% and 26.7%, respectively; and the AUC was 0.582. The AUC for the APMT model was significantly higher than the SMI model (P < 0.001).

Conclusions: The results of this study show that the cut-off value of APMT for determining the gait independence was 13 mm. In addition, APMT had a higher accuracy of determining gait independence than SMI. This indicates that measuring APMT is more useful for predicting gait independence than SMI in community-dwelling older adults undergoing outpatient rehabilitation.

在接受门诊康复的社区老年人中，使用拇内收肌厚度和骨骼肌质量指数来确定步态独立性的准确性。

目的：利用拇内收肌厚度（APMT）和骨骼肌质量指数（SMI）测定社区老年人门诊康复患者步态独立性的准确性尚不清楚。本研究的目的是比较在接受门诊康复的社区老年人中使用APMT和SMI测定步态独立性的准确性。方法：本研究纳入98例老年人（平均年龄85.2岁）。参与者每周接受一到三次门诊康复治疗。主要结果为步态独立性（功能独立性测量步态评分：6分或7分）、骨骼肌质量指数（SMI）和APMT，建立APMT和SMI对步态独立性的受试者工作特征（ROC）曲线，并利用约登指数计算截断值。此外，采用Delong检验比较了APMT模型和SMI模型的曲线下面积（AUC） s。结果：在98名参与者中(男性；19岁的女性;79例)，步态独立组53例（54.1%）。ROC曲线计算APMT的截止值为13 mm；敏感性67.9%，特异性86.7%；AUC为0.800。根据ROC曲线计算SMI的临界值为4.6 kg/m2；敏感性和特异性分别为90.6%和26.7%；AUC为0.582。APMT模型的AUC显著高于SMI模型(P)。结论：本研究结果表明，APMT判断步态独立性的截止值为13 mm。此外，APMT在确定步态独立性方面比SMI具有更高的准确性。这表明测量APMT在预测接受门诊康复的社区居住老年人的步态独立性方面比SMI更有用。

期刊介绍： European Geriatric Medicine is the official journal of the European Geriatric Medicine Society (EUGMS). Launched in 2010, this journal aims to publish the highest quality material, both scientific and clinical, on all aspects of Geriatric Medicine. The EUGMS is interested in the promotion of Geriatric Medicine in any setting (acute or subacute care, rehabilitation, nursing homes, primary care, fall clinics, ambulatory assessment, dementia clinics..), and also in functionality in old age, comprehensive geriatric assessment, geriatric syndromes, geriatric education, old age psychiatry, models of geriatric care in health services, and quality assurance.
