The respective contributions of the stroke and undamaged hemispheres to motor recovery after stroke remains controversial. The aim of this article is to evaluate the relationship between location and size of cortical motor areas and outcome after stroke. Twelve controls and 12 stroke patients were studied. Hand cortical motor output areas were determined using transcranial magnetic stimulation. Motor-evoked potentials were recorded simultaneously from both hands. Functional motor abilities were evaluated using well-validated measures. Surface area, weighted surface area, and center of gravity of motor output areas were calculated. Different patterns of motor output areas to the paretic hand were observed; there was no motor output from the stroke hemisphere in patients with poor outcome, contrasting to large motor output area in the stroke hemisphere in patients with good outcome, regardless of infarct size or location. A significant correlation was found between measures of motor outcome in the stroke-affected upper extremity and both the surface area and weight of the central motor output area in the stroke hemisphere. No ipsilateral motor response was obtained after stimulation of either hemisphere. These data support an association between preservation of cortical motor output area to the paretic hand in the stroke hemisphere and good motor outcome.

Human ischaemic stroke is a multistage disorder with various routes of recovery. Neuroimaging allows researchers to explore the pathophysiology and recovery mechanismsin vivo. Based on these findings, motor recovery and chronic motor impairment after stroke have been linked to structural alterations of grey and white matter as well as functional changes in the perilesional tissue. Parameters derived from diffusion tensor imaging and functional magnetic resonance imaging can be used as surrogate markers of chronic motor impairment and predictors of functional potential for motor recovery. These parameters have the potential to tailor individual rehabilitation and stratify patients for experimental therapy studies such as invasive and non-invasive brain stimulation alone or in combination with other facilitators.
