Objective The majority of patients with stroke survive the acute episode and live with enduring disability. Effective therapies to support recovery of motor function after stroke are yet to be developed. Key to this development is the identification of neurophysiologic signals that mark recovery and are suitable and susceptible to interventional therapies. Movement preparatory low‐frequency oscillations (LFOs) play a key role in cortical control of movement. Recent animal data point to a mechanistic role of motor cortical LFOs in stroke motor deficits and demonstrate neuromodulation intervention with therapeutic benefit. Their relevance in human stroke pathophysiology is unknown. Methods We studied the relationship between movement‐preparatory LFOs during the performance of a visuomotor grip task and motor function in a longitudinal (&lt;5 days, 1 and 3 months) cohort study of 33 patients with motor stroke and in 19 healthy volunteers. Results Acute stroke–lesioned brains fail to generate the LFO signal. Wher...
