How surgical nerve rerouting techniques work in synergy with advanced neural interface electronics to maximize prosthetic control.
In TMR surgery, severed residual motor nerves (median, ulnar, musculocutaneous) are transferred to reinnervate non-functional residual muscle segments, creating biological biological amplifiers of neural motor intent.
Combining high-density myoelectric arrays placed over TMR muscle targets with direct intraneural electroneurographic (ENG) electrodes provides redundant, robust control signals for multi-articulating bionic fingers.
Rather than clumsily switching between wrist rotation and hand grasp modes, deep neural decoders interpret compound motor intent, allowing patients to reach, rotate, and grasp in a fluid, natural movement.
