    Area of Science:

    • Biomedical Engineering
    • Rehabilitation Technology
    • Neuroprosthetics

    Background:

    • Limb amputation results in loss of both mechanical and sensory function.
    • Existing prosthetic hands often face psychological rejection due to lack of sensory feedback.
    • Sensory feedback is crucial for improving user acceptance and functional integration of artificial limbs.

    Purpose of the Study:

    • To investigate the impact of integrating a sense of touch into myoelectrically controlled prosthetic hands.
    • To evaluate user acceptance and confidence levels with sensory-enabled prosthetic limbs.
    • To assess the safety and efficacy of electrical sensory feedback stimulation.

    Main Methods:

    • Fitted two patients with myoelectrically controlled electric hands incorporating tactile sensory feedback.

  • Conducted a nine-month trial period to gather user feedback and assess performance.
  • Monitored for adverse skin reactions to the electrical feedback stimulus.

    • Main Results:

    • Patients reported favorably on the prosthetic fittings with integrated sensory feedback.
    • No adverse skin reactions were observed during the trial period.
    • Users reported increased confidence in utilizing the prosthesis due to the sensory feedback.

    Conclusions:

    • Integrating tactile sensory feedback into myoelectric prosthetic hands enhances user confidence and acceptance.
    • Electrical sensory feedback is a safe and effective method for improving prosthetic limb functionality.
    • Addressing sensory deficits is critical for overcoming psychological rejection and improving outcomes in upper-limb prosthetics.
