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 the12 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 group 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.
