关键词: Motor cortex stimulation Central post-stroke pain Neuropathic pain symptom inventory Mechanism Predictor

摘要:
Motor cortex stimulation (MCS) has been used in the treatment of chronic neuropathic pain for more than 25 years. However, the mechanisms and outcome predictors still represent major challenges. To investigate outcome predictors and potential mechanisms of MCS on central post-stroke pain (CPSP). 16 CPSP patients were analyzed at our center. The pain intensity was assessed using a visual analog scale (VAS) before surgery and at the last follow-up. The Neuropathic Pain Symptom Inventory (NPSI) was used to assess pain intensity, analyze outcome predictors, and indicate potential mechanisms of MCS. The mean VAS score before surgery (8.0 ± 0.7) was significantly higher than that of the last follow-up (5.3 ± 2.4, p < 0.001). Similarly, the mean total NPSI score before MCS (30.6 ± 12.2) was significantly reduced at the last follow-up (25.2 ± 15.1, p = 0.01). An analysis of the NPSI subscores revealed a significant association between burning pain relief and effective results (p = 0.041, Fisher's exact test). Burning pain relief might predict long-term results for the therapeutic use of MCS in CPSP. The substantia gelatinosa may play an important role in the modulation of pain relief mediated by MCS. © 2018 S. Karger AG, Basel.
