Effects of Unilateral Electrical Stimulation of Lower Limbs on Cerebral Cortex:A Study with Functional Mag-netic Resonance Imaging in Health Men / 中国康复理论与实践

ABSTRACT

Objective To investigate the effect of unilateral electric stimulation of lower limbs movement on central nervous system. Methods 8 right-footed healthy men accepted electrical stimulation to evoke dorsiflexion of the right ankle, while the cerebral cortex activa-tions were observed with functional magnetic resonance imaging. Results For electrical stimulation evoked contraction task, the significant activations were observed in the bilateral primary motor cortex, primary sensory area, secondary somatosensory cortex, cingulated gyrus;ip-silateral premotor area and contralateral supplementary motor area. Conclusion Unilateral electrical stimulation may result in activations of bilateral cerebral cortex.
