Abstract — Body composition and metabolism may change considerably after traumatic amputation because of muscle atrophy and an increase in adiposity. The purpose of this study was to quantify changes in weight, body composition, and metabolic rate during the first year following traumatic amputation in military servicemembers. Servicemembers without amputation were included for comparison. Participants were measured within the first 12 wk after amputation (baseline) and at 6, 9, and 12 mo after amputation. Muscle mass, fat mass, weight, and metabolic rate were measured at each time point. There was a significant increase in weight and body mass index in the unilateral group between baseline and all follow-up visits (p < 0.01). Over the 12 mo period, total fat mass and trunk fat mass increased in both unilateral and bilateral groups; however, these changes were not statistically significant over time. Muscle mass increased in both the unilateral and bilateral groups despite percent of lean mass decreasing. No changes in resting metabolism or walking energy expenditure were observed in any group. The results of this study conclude that weight significantly increased because of an increase in both fat mass and muscle mass in the first year following unilateral and bilateral amputation.

Key words: amputation, atrophy, body composition, body mass index, DXA, fat mass, metabolism, muscle mass, trauma, unilateral, weight gain.
