Objective To observe the short-term effects of short-term spinal cord electrical stimulation (SCS) for the treatment of patients with sub-acute herpetic neuralgia. Methods Twenty-three patients with sub-acute herpetic neuralgia of both sexes, aged 60-80 years, were treated with short-term spinal electrical cord stimulation from January 2016 to June 2018 in the Department of Pain Medicine and Department of Neurology of Guizhou Provincial People's Hospital. SCS is a neuromodulation method by placing the stimulating electrode in the epidural space and using current to stimulate the posterior horn sensory neurons and posterior column conduction bundle. VAS was assessed before the treatment and at the 1 day, 3 days, 1 week, 1 month and 3 months after the treatment. Sleep quality score was evaluate quality of sleep at different times. Results The pain relief was remarkable at different times after SCS in all patients. The VAS was 1.48±1.27, 1.35±1.19, 1.13±0.97, 2.96±1.94, 3.34±2.14 at 1 day, 3 days, 1 week, 1 month and 3 months after the treatment respectively, with statistical difference compared with the pretreatment (6.57±1.53)(P<0.01). The effective rates were 82.6%(9/23), 87.0%(20/23), 91.3%(21/23), 21.7%(5/23), 17.4%(4/23) at 1 day, 3 days, 1 week, 1 month and 3 months after treatment respectively. The sleep quality scores were significantly increased at different times after stimulation SCS. Conclusion Short-term spinal cord electrical stimulation can alleviate pain and improve the quality of sleep for the patients with sub-acute herpetic neuralgia.
