Motor control shows differing effects on bimanual coordination in 116 participants, indicating asymmetries in visual feedback perturbation.

This research investigates how visual feedback perturbations affect bimanual coordination involving different motor functions.
Participants performed a bimanual coordination task controlling a cursor and matching orientation.
Groups experienced visual feedback perturbations in either trajectory or orientation.
Coordination and performance metrics were analyzed independent of limb dominance.
Rapid adaptation to visual feedback perturbations was observed in the trajectory-controlling limb.
Limited impact of orientation feedback perturbation on trajectory metrics was noted.
Significant changes in limb coordination occurred with trajectory feedback perturbations.

Kanapskyte et al. (2025) studied this question.
