ABSTRACT
ObjectiveTo observe the effect of transcranial direct current stimulation (tDCS) combined with task-oriented rehabilitation training single pellet reaching and grasping (SPG) on the motor function of forelimb in rats with unilateral contusion of C5 spinal cord. MethodsA total of 60 adult male Sprague-Dawley rats were randomly divided into sham operation group (sham group), spinal cord injury (SCI) group, tDCS group, SPG group, false group and tDCS+SPG group, with ten rats in each group. Only C5 lamina was removed in the sham group, and the C5 spinal cord contusion model was established by IH spinal cord impactor in the other five groups. The rats received tDCS in tDCS group, SPG in SPG group, tDCS without current in false group, tDCS combined with SPG in tDCS+SPG group, and no treatment in the SCI and the sham groups. The rats were evaluated with Rearing and Grooming tests, and motor-evoked potential (MEP). ResultsFour weeks after operation, compared with SCI group, the scores of Rearing and Grooming increased in tDCS group and tDCS+SPG group (P < 0.05), and they were more in the tDCS+SPG group than in tDCS group and SPG group (P < 0.05); the score of Grooming increased in SPG group (P < 0.05); while the amplitude of MEP increased in tDCS group, SPG group and tDCS+SPG group (P < 0.05), and the latency shortened in tDCS group and tDCS+SPG group (P < 0.05); and the amplitude increased more in tDCS+SPG group than in tDCS group and SPG group (P < 0.01). ConclusiontDCS could promote the recovery of motor function in rats with SCI, and the combination therapy of tDCS and task-oriented rehabilitation training is more effective.
