Lower extremity amputees expend more energy walking than non-amputees, with higher amputation levels increasing metabolic demand. Prosthesis selection and physical conditioning can potentially reduce this energy cost.

Area of Science:

  • Biomechanics
  • Rehabilitation Medicine
  • Prosthetics

Background:

  • Quantifying energy expenditure during ambulation in lower extremity amputees is challenging due to inconsistent study parameters.
  • Existing literature indicates a higher energy cost of ambulation for amputees compared to non-amputees.

Purpose of the Study:

  • To review and synthesize the literature on energy expenditure during ambulation in individuals with lower extremity amputations.
  • To identify factors influencing energy cost, including amputation level, surgical procedures, and prosthetic devices.
  • To provide recommendations for clinical practice regarding surgical and prosthetic selection, and the role of physical conditioning.

Main Methods:

  • Literature review and synthesis of studies comparing energy expenditure during ambulation in healthy individuals and lower extremity amputees.

  • Analysis of factors such as amputation level, surgical techniques, and prosthetic types on metabolic demand.
  • Evaluation of the potential impact of physical training and conditioning on energy cost.

    • Main Results:

    • Higher amputation levels are associated with increased metabolic demand.
    • Certain prosthetic components, like the CAT-CAM socket and Proteor foot, may reduce energy expenditure.
    • Surgical procedures and prosthetic choices significantly influence the energy cost of ambulation.

    Conclusions:

    • Energy cost of ambulation should be a key consideration in surgical procedure selection and prosthetic fitting for lower extremity amputees.
    • Physical conditioning and training may decrease the metabolic cost of ambulation, especially for individuals with cardiopulmonary or vascular issues.
    • Further research is needed to establish optimal exercise regimens for reducing metabolic costs in this population.
