Does unilateral transtibial amputation lead to greater metabolic demand during walking?

This study compares the metabolic demand of walking in young, active individuals with traumatic unilateral transtibial amputation and nondisabled controls. Results show equivalent metabolic demand between groups, highlighting the physical fitness of servicemembers with amputation. The findings may guide future outcome expectations in this population.

  2. Aim • Compare metabolic demand of walking in young, active individuals with traumatic unilateral transtibial amputation (TTA) and nondisabled controls. • Relevance • Previous literature reports greater metabolic demand of walking following transtibial amputation. • However, most research focuses on relatively older, less active, and often dysvascular amputees, while service-members with traumatic amputation are typically young, fit, and highly active.

  3. Method • Heart rate (HR), rate of oxygen consumption, and rating of perceived exertion (RPE) were calculated as subjects walked at a self-selected velocity and at 5 standardized velocities based on leg length. • TTA group also completed the Prosthetics Evaluation Questionnaire.

  4. Results • Oxygen consumption, net oxygen consumption, and RPE did not differ between groups. • Compared with controls, HR was greater in TTA group and increased to a greater extent with velocity. • Overall, TTA group rated their walking abilities as high.

  5. Conclusion • This is the first study to report equivalent metabolic demand between persons with amputation and controls walking at the same velocity. • These results may reflect the physical fitness of young servicemembers with traumatic amputation and may serve to guide future outcome expectations.
