[Purpose] This study was aimed at investigating the relationship between skeletal muscle mass and muscle quality by using bioelectrical impedance analysis and ambulatory independence in patients with proximal femoral fractures. [Participants and Methods] The study included 120 patients admitted to a recovery rehabilitation unit for whom follow-up assessments were available. Skeletal muscle mass and phase angle were assessed using bioelectrical impedance analysis upon admission. The patients were divided into the following two groups based on their Functional Independence Measure gait score at discharge: gait-independent group (gait score: ≥6; n=74) and gait-dependent group (gait score: ≤5; n=46). [Results] The phase angle was associated with gait independence. The cut-off values for the phase angle predicting gait independence were 4° and 3.8° for male and female patients, respectively, a more accurate assessment compared with skeletal muscle mass analysis. [Conclusion] The phase angle was associated with gait independence in patients with proximal femoral fractures. The results of this study suggest that the evaluation of the phase angle is important for predicting gait independence in patients with proximal femoral fractures.
[目的] 本研究旨在通过生物电阻抗分析以及评估股骨近端骨折患者的动态独立性，来研究骨骼肌质量与肌肉质量之间的关系。[参与者与方法] 本研究纳入了120名入住康复康复单元且有随访评估数据的患者。入院时采用生物电阻抗分析评估骨骼肌质量和相位角。根据患者出院时的功能独立性测量步态评分，将患者分为以下两组：步态独立组（步态评分：≥6；n = 74）和步态依赖组（步态评分：≤5；n = 46）。[结果] 相位角与步态独立性相关。预测男性和女性患者步态独立性的相位角临界值分别为4°和3.8°，与骨骼肌质量分析相比，这是一种更准确的评估方法。[结论] 相位角与股骨近端骨折患者的步态独立性相关。本研究结果表明，评估相位角对于预测股骨近端骨折患者的步态独立性很重要。
