This retrospective, observational study was designed to investigate factors affecting successful prosthetic ambulation in elderly amputees aged > or = 60 years. The study included 64 unilateral transfemoral or hip disarticulation amputees. Patients who were able to walk > or = 100 m with prosthesis were classified as successful and those who could walk < 100 m as failures. Age, comorbidities, cause of amputation, ability to stand on one leg, patient's motivation for walking and maximum oxygen uptake as a proportion of predicted maximum oxygen uptake (%VO(2max)) during an exercise load test were examined as indicators of physical fitness. Significant differences were noted between the two groups in the number of comorbidities, ability to stand on one leg, patient's motivation for walking and mean %VO(2max). A low number of comorbidities, the ability to stand on one leg, motivation for walking and adequate physical fitness allowing an exercise intensity of > or = 50% VO(2max) were considered to be predictive factors for successful prosthetic rehabilitation.
这项回顾性观察研究旨在调查影响60岁及以上老年截肢者成功使用假肢行走的因素。该研究纳入了64名单侧经股骨截肢或髋关节离断截肢者。能够使用假肢行走100米及以上的患者被归类为成功，而行走距离小于100米的患者则为失败。研究将年龄、合并症、截肢原因、单腿站立能力、患者行走动力以及运动负荷测试期间的最大摄氧量占预测最大摄氧量的比例（%VO₂max）作为身体素质指标进行了检查。两组在合并症数量、单腿站立能力、患者行走动力和平均%VO₂max方面存在显著差异。合并症数量少、单腿站立能力、行走动力以及允许运动强度达到或超过50%VO₂max的足够身体素质被认为是假肢康复成功的预测因素。
