Description

Julien Rossato and colleagues showed in 2026 that one muscle's surface signals can steer both natural and extra movement directions at once. Motor neurons in one pool may carry several independent inputs, yet tapping them usually needs hard signal decomposition. Fifteen volunteers moved a cursor by hand force while rotating it by shifting patterns from a 64-channel grid on the biceps, without any decomposition step.

Volunteers hit targets in 89% of trials on average, and cursor rotations beat force-only trials in 84% of cases. Pattern shifts stayed distinct from simple amplitude changes, fitting independent neural inputs, though activation shifts may partly explain them. The method opens simpler prosthetic and rehab controls, letting one muscle command an extra degree of freedom alongside its natural job.
