Discussion

Direct neural recordings improved phantom limb movement prediction in transfemoral amputees, suggesting effective prosthetic control.

Direct neural recordings demonstrate the ability to predict phantom limb movement attempts, improving prosthetic control accuracy.
Decoding accuracy increased by capturing a broader signal bandwidth, including intraneural and inter-muscular activity.
Transversal intrafascicular multichannel electrodes enabled effective interfacing with nerve fibers for recording motor signals.
Findings indicate early segregation of motor and sensory fibers in the tibial nerve, guiding future neural interface designs.

Rossi et al. (2025) studied this question.
