Advanced technologies for intuitive control and sensation of prosthetics

Area of Science:

• Prosthetic Technology
• Neuroprosthetics
• Rehabilitation Engineering

Background:

• Significant investment over 25 years by DoD, VA, and NIH aims to improve life for those with limb loss.
• Electromyography (EMG) control since the 1980s lacks intuitiveness and sensory feedback.
• Recent progress includes intuitive EMG control and meaningful sensory perception through stimulation.

Purpose of the Study:

• Review the state-of-the-science in intuitive prosthetic control and sensation.
• Discuss future research directions in prosthetic device development.
• Explore advancements applicable to both upper and lower limb amputations.

Main Methods:

• Review of current research and development efforts.
• Examination of external and implanted prosthetic systems.
• Exploration of surgical and regenerative approaches.

Main Results:

• Substantial advancements in prosthetic control and sensory perception over the past decade.
• Development of intuitive EMG control methods.
• Emergence of bidirectional neuroprostheses for enhanced limb function.

Conclusions:

• Prosthetic technology is rapidly evolving towards more intuitive control and sensory feedback.
• Future research should focus on integrated systems, surgical interventions, and regenerative medicine.
• These advancements promise to significantly improve function and quality of life for amputees.
