Factors affecting prosthetic rehabilitation outcomes in amputees of age 60 years and over.

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.
