Résumé : |
"Objective To investigate whether the aerobic capacity of older adults who underwent a lower limb amputation is associated with the presence, cause (traumatic or vascular), and level of amputation (transtibial or transfemoral). Design Cross-sectional descriptive. Setting Human motion laboratory at a rehabilitation center. Participants Older subjects (n=36) who underwent lower limb amputation and age-matched, able-bodied controls (n=21). All subjects were able to walk for a minimum of 4 minutes. Interventions Not applicable. Main Outcome Measure Peak oxygen consumption (Vo2peak) was measured using open-circuit respirometry while performing a discontinuous, graded, 1-legged, peak cycle exercise test. Results After correcting for age, body mass index, and sex, the multiple linear regression analysis revealed that subjects who underwent amputation had a 13.1% lower aerobic capacity compared with able-bodied controls (P=.021). Differentiation among etiologies revealed that subjects with a vascular amputation had a lower Vo2peak of 29.1% compared with able-bodied controls (P<.001 whereas traumatic amputees did not differ from able-bodied controls after correcting for etiology no association between level of amputation and vo2peak was found> Conclusions Older adults who underwent an amputation because of vascular deficiency had a lower aerobic capacity compared with able-bodied controls and people with a traumatic amputation. The level of amputation was not associated with Vo2peak." |
