Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Rehabilitation Medicine

Background:

  • Conventional myoelectric prostheses offer limited intuitive control.
  • Upper limb amputations, particularly high-level ones, present significant functional challenges.

Observation:

  • Target motor reinnervation (TMR) generates additional myoelectric control signals.
  • Target sensory reinnervation (TSR) can provide sensory feedback localized to the missing limb.

Findings:

  • TMR enables simultaneous operation of multiple prosthesis functions via physiologically appropriate pathways.
  • TSR offers the potential for intuitive sensory feedback, mimicking natural limb sensation.

Implications:

  • These reinnervation techniques can significantly improve the functionality of externally powered prostheses.
