In neuroimaging studies of stroke patients, coactivation may account for increased recruitment of bilateral motor areas when moving the affected limb. Here we studied eight patients after stroke with fMRI and simultaneous EMG. Bilateral recruitment of premotor and primary motor cortices was evident in five patients with strictly unilateral performance per EMG. Because patients had excellent motor recovery, this increased recruitment suggests an adaptive response to the infarct.
