Description

Kiara Quinn and co-authors show, in twenty twenty-six, that reinnervating muscle targets makes motor unit signals easier to separate after nerve transfer surgery. After amputation, prostheses often decode intent from pooled muscle signals, which limits natural control. Splitting the signal into single motor units promises finer control, but overlapping units blur together. The team tested direct nerve-to-muscle implantation in a rodent hindlimb model. Tissue and electrical analyses followed the reinnervation.

Structural changes after surgery spread motor unit signals farther apart in space than in intact muscle. That separation meant fewer complex, overlapping signals in recordings. The team used the cleaner signals for a first proof-of-concept: precise control of a virtual prosthesis after direct nerve-to-muscle implantation.
