There exists a dearth of evidence on rehabilitation factors that influence prosthetic mobility in people with lower limb amputation (LLA). Examining variables that contribute to prosthetic mobility can inform rehabilitation interventions, providing guidance in developing more comprehensive care for these individuals.
To determine the influence of modifiable and non-modifiable variables related to LLA and their impact on prosthetic mobility, using the International Classification of Functioning, Disability and Health (ICF) model. Secondarily, to determine if personal factors and self-reported balance and mobility are predictive of Component timed-up-and-go (cTUG) performance.
Cross-sectional study of a convenience sample.
National conference.
People (N=68) with non-vascular causes of unilateral LLA.
Assessment of anthropometrics, mobility, bilateral hip extensor strength, hip range of motion, single limb balance, and self report measures. Lasso linear regression and extreme gradient boosting analyses were used to determine influence of variables on prosthetic mobility.
Timed performance of the cTUG.
The following five variables were found to influence basic prosthetic mobility (P ≤ .05) in people with transtibial amputation: hip extensor strength, hip range of motion, single limb balance, waist circumference, and age. In the transfemoral cohort, number of comorbidities and waist circumference primarily influenced prosthetic mobility. Additionally, 66% of the variance in cTUG total time for the entire sample could be explained by simply regressing on level of amputation, number of comorbidities, age and Activities-specific Balance Confidence scale score, all variables easily collected in a waiting room.
Variables that are modifiable with physical therapy intervention including hip extensor strength, hip range of motion, single limb balance, and waist circumference significantly influenced basic prosthetic mobility. These variables can be affected by targeted rehabilitation interventions and lifestyle changes.

下肢截肢患者（LLA）的康复因素对假肢移动性的影响证据不足。检查有助于假肢移动性的变量可以为康复干预措施提供信息，为这些人提供更全面的护理指导。
使用国际功能、残疾和健康分类（ICF）模型，确定与 LLA 相关的可改变和不可改变变量的影响及其对假肢移动性的影响。其次，确定个人因素和自我报告的平衡和移动性是否可预测组件计时起立行走（cTUG）的表现。
便利样本的横断面研究。
全国会议。
非血管性单侧 LLA 患者（N=68）。
评估人体测量学、移动性、双侧髋关节伸肌力量、髋关节活动范围、单腿平衡和自我报告测量。使用套索线性回归和极端梯度增强分析来确定变量对假肢移动性的影响。
cTUG 的计时性能。
发现以下五个变量会影响胫骨截肢患者的基本假肢移动性（P≤.05）：髋关节伸肌力量、髋关节活动范围、单腿平衡、腰围和年龄。在股骨截肢队列中，主要影响假肢移动性的是合并症数量和腰围。此外，整个样本的 cTUG 总时间的 66%可以通过简单地回归截肢水平、合并症数量、年龄和活动特异性平衡信心量表评分来解释，所有这些变量都可以在候诊室轻松收集。
可以通过物理治疗干预改变的变量，包括髋关节伸肌力量、髋关节活动范围、单腿平衡和腰围，对基本假肢移动性有显著影响。这些变量可以通过针对性的康复干预和生活方式改变来影响。
