The aim of the study was to establish normative values of lower limb amputation mobility across primary etiologies based on age and amputation level.
This study is a cross-sectional observational analysis of outcomes. A total of 11,995 lower limb prosthesis users were included in the analysis. Participants were grouped by etiology into four categories: cancer, congenital, trauma, and diabetes/dysvascular. Mobility was assessed by using the Prosthetic Limb Users Survey of Mobility.
Mobility across seven age groups for the four etiologies was established for both above-the-knee amputation and below-the-knee amputation. Differences were found between age groups for individuals: above-the-knee amputation: cancer (χ 2 (6) = 40.97, P < 0.001), congenital (χ 2 (3) = 9.41, P = 0.024), trauma (χ 2 (6) = 18.89, P = 0.004), and dysvascular (χ 2 (5) = 39.73, P < 0.001; below-the-knee amputation: cancer (χ 2 (6) = 29.77, P < 0.001), trauma (χ 2 (6) = 28.22, P < 0.001), and dysvascular (χ 2 (6) = 144.66, P < 0.001).
The awareness of differences across amputation etiologies extending across the lifespan of ages can assist the goal-setting process as part of prosthetic rehabilitation. In addition, refined normative values provide the ability to benchmark new and innovative changes in clinical practice.
本研究旨在根据年龄和截肢部位，为主要病因导致的下肢截肢者制定移动能力的正常值。
这是一项关于结局的横断面观察性分析研究。共纳入 11995 名下肢假体使用者进行分析。参与者按病因分为四类：癌症、先天性、创伤和糖尿病/血管病变。使用假体使用者移动能力调查问卷评估移动能力。
为四种病因的所有 7 个年龄组的膝上截肢和膝下截肢建立了移动能力正常值。在年龄组之间，发现了个体之间的差异：膝上截肢：癌症（χ 2 (6) = 40.97，P < 0.001）、先天性（χ 2 (3) = 9.41，P = 0.024）、创伤（χ 2 (6) = 18.89，P = 0.004）和血管病变（χ 2 (5) = 39.73，P < 0.001）；膝下截肢：癌症（χ 2 (6) = 29.77，P < 0.001）、创伤（χ 2 (6) = 28.22，P < 0.001）和血管病变（χ 2 (6) = 144.66，P < 0.001）。
认识到各种病因导致的截肢者在整个生命周期内的差异，可以帮助设定假肢康复的目标。此外，细化的正常值为基准评估临床实践中的新的创新变化提供了能力。
