Because FIM total scores at the time of hospital admission and discharge are highly correlated, FIM total scores at the time of hospital admission can be used to establish a rehabilitation program, to inform the patient and family about the possibility of recovery, and to assess the amount and quality of care given in the home or discharge placement.

This study showed that the physical fitness of amputees was clearly lower than that of the able-bodied subjects and that the amputees were able to recover from a poorly conditioned status after endurance training.

In this study, independent ambulation of at least 100 metres with/without a cane was regarded as successful prosthetic rehabilitation. The subjects were classified into two groups according to this criterion at the time of discharge. The successful group attained this performance, the other group failed to reach this level. The successful group included 8 unilateral trans-femoral amputees aged 72.2 +/- 2.1 years who underwent amputation at more than 70 years, and succeeded in walking with a prosthesis. The group which failed included 9 unilateral trans-femoral amputees aged 63.2 +/- 2.1 years who underwent amputation between the ages of 60-65 years, and had great difficulty in walking with a prosthesis. The purpose of this research was to investigate whether or not %VO2max as an indicator of physical fitness is useful in predicting prosthetic rehabilitation outcome after dysvascular amputation by comparing these two groups. Evaluation of physical fitness was conducted before the subjects began prosthetic rehabilitation. Information about each subject before fitting with a prosthesis was collected retrospectively from clinical charts made during admission. The successful group were capable of strenuous exercise, reaching the intensity of 50% VO2max or more. In the group which failed only one reached the intensity of 50% VO2max. The working capacity of 50% VO2max or greater would appear to be a valid initial guideline level of physical fitness at which an amputee can expect to succeed in walking with a prosthesis. Apart from physical fitness, a lesser number of comorbidity, good ability to stand on the remaining leg, and a strong will to walk were found to be important factors contributing to successful prosthetic rehabilitation. This study also showed that age alone was not an important factor.

Chin T, Sawamura S, Shiba R, Oyabu H, Nagakura Y, Takase I, Machida K, Nakagawa A: Effect of an Intelligent Prosthesis (IP) on the walking ability of young transfemoral amputees: Comparison of IP users with able-bodied people. Am J Phys Med Rehabil 2003;82:447-451. Objective: To make a comparative study of energy expenditure and walking speeds between able-bodied people and young Intelligent Prosthesis (IP) users and to demonstrate the effect of IP on the walking ability of young amputees. Design:The test subjects were eight young traumatic transfemoral amputees. Fourteen able-bodied persons served as controls. All amputees used an IP, and they had all undergone a prosthetic rehabilitation program for 8 wk. IP users, who had completed the rehabilitation program, were instructed to walk at speeds of 30, 50, 70, 90, and 110 m/min. Measurements of energy expenditure while walking were taken. The most metabolically efficient waking speed was also determined.Results: On average, the IP users experienced an oxygen uptake that was 24.1% and 24.2% higher than those for the controls at speeds of 70 and 90 m/min, respectively. It was also determined that the most metabolically efficient walking speed for the IP users was the same as for the controls. Conclusions:This study showed that young IP users who undergo an adequate prosthetic rehabilitation program can achieve remarkably improved walking performance. Young IP users could walk at the normal speeds of able-bodied people, with only around a 24% increase in energy expenditure
