Motor Control Function of Brain in Subacute Complete Spinal Cord Injured Patients: A Functional Magnetic Resonance Imaging Study / 中国康复理论与实践

ABSTRACT

Objective:To study the changes of brain motor control function in patients with complete spinal cord injury within three to six months. Methods:From January, 2017 to January, 2019, eleven inpatients with complete spinal cord injury and twelve healthy controls were screened with functional magnetic resonance imaging during attempted/executive movement (MA/ME) and motor imagery (MI). The involved area and activation were compared between the groups under tasks. Results:More areas were activated in the patients than in the controls as MA/ME, such as bilateral primary sensorimotor cortex, supplementary motor area, lateral globus pallidus, cerebellum, contralateral thalamus and putamen. During MI, the activation was more in the patients in ipsilateral primary motor cortex, supplementary motor area, dorsal premotor area, contralateral supplementary motor area, insular and basal ganglia. The patients induced more activation as MA than as MI in ipsilateral primary motor cortex, bilateral supplementary motor area and cingulate motor area, and contralateral cerebellum. Conclusion:The activation remains normal in primary motor cortex and supplementary motor area for subacute complete spinal cord injury patients when undergoing motor tasks, but some reorganization may occur in parietal lobe and cerebellum that involve in sensorimotor integration.
