Numerous factors can affect mobility of individuals with lower limb amputation, including prosthesis-dependent, physical and psychological determinants.Objective:This study aimed to investigate the prosthesis and health-related factors of mobility in people with nontraumatic unilateral transtibial amputation.Study Design:Cross-sectional observational study.
Individuals with nontraumatic unilateral transtibial amputation who are using a prosthetic leg were included. All participants were asked to fill out the Prosthesis Evaluation Questionnaire, 12-Item Short-Form Health Survey (SF-12), Comprehensive Lower Limb Amputee Socket Survey, and 12-item Prosthetic Limb Users Survey of Mobility. The relationships between the variables of interest and mobility were investigated using correlation coefficient analyses. Multiple regression analysis was run to investigate the impact of a set of predictor variables on mobility.
A total of 168 people with lower limb amputation were included. Mobility had a significant association with age, comorbidity, occupation, Prosthesis Evaluation Questionnaire score, physical and mental component scores of SF-12, subscales of the Comprehensive Lower Limb Amputee Socket Survey, educational status, amputation cause, time since amputation, time since using the prosthesis, and socket insert type. In the final model of multiple regression analysis, the Physical Component Summary score of SF-12 showed the strongest predictor of mobility (beta = 0.40, p < 0.001).
Nonprosthetic factors play a significant role in mobility of people with nontraumatic unilateral transtibial amputation. Although some predictors, such as age and time since amputation, are immutable, clinicians may still enhance the mobility of this population through the utilization of health-related factors, such as improving their physical activity.
众多因素会影响下肢截肢患者的活动能力，包括对假肢的依赖、身体和心理方面的决定因素。
本研究旨在调查非创伤性单侧胫部截肢患者活动能力的假肢及健康相关因素。
横断面观察性研究。
纳入使用假肢的非创伤性单侧胫部截肢患者。所有参与者均被要求填写假肢评估问卷、12项简明健康调查（SF - 12）、下肢截肢者全接受腔综合调查问卷以及12项假肢使用者活动能力调查问卷。使用相关系数分析来研究感兴趣的变量与活动能力之间的关系。进行多元回归分析以研究一组预测变量对活动能力的影响。
共纳入168例下肢截肢患者。活动能力与年龄、合并症、职业、假肢评估问卷得分、SF - 12的身体和心理成分得分、下肢截肢者全接受腔综合调查问卷的子量表、教育状况、截肢原因、截肢后时间、使用假肢时间以及接受腔衬垫类型存在显著关联。在多元回归分析的最终模型中，SF - 12的身体成分汇总得分显示出对活动能力最强的预测作用（β = 0.40，p < 0.001）。
非假肢因素在非创伤性单侧胫部截肢患者的活动能力中起重要作用。尽管一些预测因素，如年龄和截肢后时间是不可改变的，但临床医生仍可通过利用与健康相关的因素，如改善他们的身体活动，来提高这一人群的活动能力。
