ABSTRACT
STUDY PURPOSE:The aim of the study was to investigate the use of electrical cortical stimulation of injured corticospinal tract as a means to increase the beneficial effects of rehabilitative motor therapy after SCI in rats. The study showed that a single session of electrical stimulation of the injured fibers led to an increase in corticospinal tract (CST) plasticity, and functional recovery after training
DATA COLLECTED:Female adult Lewis rats from Charles River Laboratories, Canada, weighing 180-220 g were used for this dataset. All rats were pre-trained in the single pellet grasping (SPG) task and received a unilateral dorsal-lateral quadrant (DLQ) spinal cord transection injury at cervical vertebrae level 4 on the side of the dominant paw. n = 11 in the stimulated group, n = 9 in control. Lesion size analysis, SPG functional scores, High Speed grasp motion analysis score, CST fiber counts, Count of Significant bins in collateral CST fiber density heatmapping data
PRIMARY CONCLUSION:Electrical stimulation of injured corticospinal fibers prior to rehabilitative training can increase their plasticity and thus the effect of rehabilitative training
