Neural interfacing architecture enables enhanced motor control and residual limb functionality postamputation

Shriya S. Srinivasan et al.

Summary: The study discusses a modified below-knee amputation procedure that incorporates agonist-antagonist myoneural interfaces (AMIs) to improve neuromuscular control and precision for amputees. Subjects who underwent this modified procedure showed better muscle control, production of distinct control signals, increased proprioceptive inputs, greater phantom limb range of motion, and reduced pain compared to those who had traditional amputations. The use of AMIs during amputation provides enhanced physiological neuromuscular dynamics, proprioception, and phantom limb perception, resulting in more differentiated electromyography for myoelectric prosthesis control and improved clinical outcomes.

Neurorobotic fusion of prosthetic touch, kinesthesia, and movement in bionic upper limbs promotes intrinsic brain behaviors

Paul D. Marasco et al.

Summary: Research shows that integrating touch, grip kinesthesia, and intuitive motor control through a neurorobotic fusion can improve behavioral performance levels for bionic prosthesis users, achieving more human-like function. Sensory-motor restoration enhances balanced decision strategies and error correction performance during object interactions.
