Active prostheses offer greater potential than passive ones by translating body movements into artificial limb function. Myoelectric prostheses utilize muscle electrical signals for advanced control and power.

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Prosthetics

Background:

  • Passive prostheses offer cosmetic function post-amputation.
  • Active prostheses enable functional restoration by translating body movements.

Purpose of the Study:

  • To explore the capabilities and control mechanisms of active prostheses.
  • To differentiate active prostheses from passive cosmetic options.

Main Methods:

  • Describing power transfer mechanisms (e.g., harnesses).
  • Explaining myoelectric control using residual limb muscle electrical signals.
  • Mentioning factors influencing range of motion.

Main Results:

  • Active prostheses can transform movements from other body regions into limb function.

  • Myoelectric prostheses feature independent drives and power sources.
  • Control is achieved via amplified electrical action potentials from residual limb muscles.

    • Conclusions:

    • Active prostheses, particularly myoelectric types, offer significant functional advantages over passive devices.
    • The technology allows for sophisticated control and powered movement in artificial limbs.
