目的：了解废用性膝关节挛缩患者日常活动能力(ADL)的影响因素。方法：采用便利抽样法，选取2022年2月至8月就诊于乌鲁木齐市某三级甲等综合医院康复科126例废用性膝关节挛缩患者为研究对象，采用一般资料调查表、视觉模拟评分量表(VAS)、徒手肌力评定(MMT)分级量表、Fugl-Meyer运动功能评定(FMA)量表、Barthel指数量表和Holden步行功能分级量表进行调研，采用单因素分析及二元Logistic回归分析废用性膝关节挛缩患者日常活动能力影响因素。结果：126例废用性膝关节挛缩患者的ADL得分为52.50(25.00,80.00)分。二元Logistic回归分析结果显示，受损范围、疼痛程度是其独立危险因素(P<0.05)，病程、肌力是其保护因素(P<0.05)。结论:废用性膝关节挛缩患者的ADL处于中等水平，受损范围、疼痛程度、病程及肌力是其日常活动能力的核心影响因素。提示临床工作者应根据废用性膝关节的影响因素有计划、有针对性地对患者实施康复手段，从而更好地减轻患者疼痛程度，提高肌力和ADL，延缓和改善膝关节挛缩进程。
