This study established the following groups of rats: a normal group, a sham surgery group, a spinal cord injury model group, a low-frequency electroacupuncture group, a high-frequency electroacupuncture group and a semen coicis group. In all but the normal and sham surgery groups, the left half of T10 was transected. Four hours after model induction, 5-Hz and 100-Hz electroacupuncture were used to stimulate the acupoints Huantiao (GB 30), Zusanli (ST 36), Zhiyang (DU 9) and Xuanshu (DU 5), or crude extract from semen coicis was intraperitoneally injected, for 8 consecutive weeks. The results indicated that electroacupuncture stimulation and intraperitoneal injection of semen coicis improved the morphology of spinal cord tissue, promoted the recovery of motion-evoked potentials, suppressed glial fibrillary acidic protein expression, and ameliorated motor function in rats with hemisection spinal cord injury. The effects of high-frequency (100 Hz) electroacupuncture and semen coicis were significant.
