The neurophysiology of sensorimotor prosthetic control

Area of Science:

• Neuroengineering
• Biomedical Engineering
• Rehabilitation Technology

Background:

• Movement is essential for daily living, and its loss significantly impacts productivity and quality of life.
• Upper limb prosthetics have advanced, but restoring natural sensorimotor (SM) control is a persistent neuroengineering challenge.
• Amputation and subsequent physiological changes complicate prosthetic control.

Purpose of the Study:

• To provide a comprehensive overview of sensorimotor neuroprostheses for upper limb loss.
• To discuss the neurophysiology of motor control in healthy and amputated individuals.
• To examine the evolution of upper limb prosthetics and current challenges.

Main Methods:

• Literature review and synthesis of current research in neuroprosthetics.
• Analysis of neurophysiological principles underlying motor control.
• Discussion of technological advancements and future directions in sensorimotor neuroprostheses.

Main Results:

• The development of upper limb prostheses has progressed from basic devices to sophisticated sensorimotor neuroprostheses.
• Restoring natural sensorimotor control remains a significant hurdle in prosthetic limb development.
• Post-injury neurophysiological changes present complex challenges for prosthetic integration and control.

Conclusions:

• Smart sensorimotor neuroprostheses hold promise for restoring lost function and improving the quality of life for individuals with upper limb loss.
• Continued research in neuroengineering and prosthetics is crucial for overcoming current limitations.
