Abstract：Objective To explore the curative effects of motor cortex stimulation (MCS) on the thalamic pain and its safety. Methods MCS was performed from January, 2017 to December, 2018 in 3 patients with unilateral limb pain induced by thalamic infarct or hemorrhage, in whom the pain was persistent, sharp and burn-like ache and intermittently aggravated. Visual analogue scale (VAS) score was 9~10 points before the MCS in the patients. The patients were treated by the drugs such as aspirin, ibuprofen and tramadol before MCS, but the pain was not relieved. The stimulative parameters were adjusted after the stimulator starting up in order to achieve the best results. All the patients were followed up for half a year. The relevant literature was reviewed. Results The postoperative VAS score was 2~3 point in the patient, in whom the limb pain was significantly relieved compared with the preoperation. Conclusion MCS is a safe and effective method to treat thalamic pain. MCS can improve the quality of the patients'life , and also it has the advantages such as less trauma and few complications.
