[Purpose] To determine which of the transcranial electromagnetic stimulation or low level laser therapy is more effective in the treatment of trigeminal neuralgia of multiple sclerosis patients. [Methods] Thirty multiple sclerosis patients of both sexes participated in this study. The age of the subjects ranged from 40 to 60 years and their mean age was (56.4-6.6). Participants were randomly selected from Dental and Neurology Outpatient Clinics at King Khalid Hospital, Najran University, Saudi Arabia. Patients were randomly divided into two equal groups of 15. The Laser group received a low level laser therapy, 830 nm wavelength, 10 Hz and 15 min duration, while the Electromagnetic group received repetitive transcranial electromagnetic stimulation at a frequency of 10 Hz, intensity of 50 mA and duration of 20 minutes. Patients were assessed pre and post treatment for degree of pain using a numerical rating scale, maximal oral mouth opening using a digital calibrated caliper, masseter muscle tension using a tensiometer and a compound action potentials of masseter and temporalis muscles. [Results] There were significant improvements after treatment in both groups, with a significant difference between the Electromagnetic and Laser groups, in favor of the Electromagnetic group. [Conclusion] Repetitive transcranial electromagnetic stimulation at 10 Hz, 50 mA, and 20 minutes duration is more effective than low level laser therapy at reducing trigeminal pain, increasing maximum oral mouth opening, masseter and temporalis muscle tension in multiple sclerosis patients.
[目的] 确定经颅电磁刺激和低强度激光治疗哪种对多发性硬化症患者的三叉神经痛治疗更有效。[方法] 30名男女多发性硬化症患者参与了本研究。受试者年龄在40至60岁之间，平均年龄为（56.4 - 6.6）岁。参与者从沙特阿拉伯纳季兰大学哈立德国王医院的牙科和神经科门诊随机选取。患者被随机分为两组，每组15人。激光组接受波长830nm、频率10Hz、持续时间15分钟的低强度激光治疗，而电磁组接受频率10Hz、强度50mA、持续时间20分钟的重复经颅电磁刺激。治疗前后使用数字评分量表评估患者疼痛程度，使用数字校准卡尺评估最大张口度，使用张力计评估咬肌张力，以及评估咬肌和颞肌的复合动作电位。[结果] 两组治疗后均有显著改善，电磁组和激光组之间存在显著差异，电磁组效果更佳。[结论] 频率10Hz、强度50mA、持续时间20分钟的重复经颅电磁刺激在减轻多发性硬化症患者的三叉神经痛、增加最大张口度、咬肌和颞肌张力方面比低强度激光治疗更有效。
