Abstract

Objectives: : This study aimed to investigate whether lower limb phase angle (LL-PA) at admission predicts functional outcomes in patients undergoing rehabilitation.

Methods: : In this retrospective study, we measured the LL-PA of 256 patients (mean age 74.09±12.86 years) admitted to a convalescent rehabilitation ward upon arrival. The primary outcomes at discharge were motor Functional Independence Measure (FIM) scores and walking independence. The secondary outcomes included a 10-m walking speed and Timed Up-and-Go test result.

Results: : The LL-PA independently predicted discharge motor FIM scores (β=0.323, P <0.001) and walking independence (odds ratio=3.302, 95% confidence interval: 1.714-6.360). The sex-specific cut-off value for predicting walking independence was 3.050° for men (sensitivity, 0.804; specificity, 0.853) and 2.650° for women (sensitivity, 0.769; specificity, 0.812).

Conclusions: : LL-PA at admission is a significant predictor of functional outcomes in patients undergoing rehabilitation, with potential utility in early prognostic assessments.

下肢相角作为康复病房患者功能预后指标的研究。

目的：本研究旨在探讨入院时下肢相角（LL-PA）是否能预测康复患者的功能结局。方法：采用回顾性研究方法，对256例入住康复病房的患者（平均年龄74.09±12.86岁）进行LL-PA测定。出院时的主要结果是运动功能独立测量（FIM）评分和行走独立性。次要结果包括10米步行速度和计时起身测试结果。结果：LL-PA独立预测出院运动FIM评分（β=0.323， P）。结论：入院时LL-PA是康复患者功能结局的重要预测因子，在早期预后评估中具有潜在的应用价值。
