肌电反馈放松训练对大学生失眠症治疗作用的初步探索

The Effects of Electromyography(EMG)Feedback and Relaxation Training on Insomnia in College Students

目的:探究肌电反馈放松训练对大学生失眠症的治疗作用。方法:采用肌电反馈放松训练对36例失眠症患者进行治疗,在治疗前后让失眠症患者填写抑郁自评量表、焦虑自评量表,并记录治疗前后被试的睡眠多导图和肌电值。结果:与治疗前相比,治疗后被试的睡眠潜伏期缩短(32.9±22.6/85.7±52.8,P=0.015),觉醒次数减少(1.8±0.8/3.5±1.5,P=0.031),快速眼动睡眠期时间延长(78.7±22.9/42.5±24.5,P=0.033),3期、4期睡眠时间延长(56.0±39.4/31.9±26.2,P=0.024),睡眠效率提高(78.1±11.2/64.3±21.3,P=0.027);焦虑自评量表得分和抑郁自评量表得分均降低(30.9±5.3/35.7±5.8、40.9±8.6/43.7±6.2,P=0.027、0.016);肌电值降低(2.6±0.9/0.8±0.2,P=0.017)。结论:肌电反馈放松训练具有放松肌肉、缓解紧张、改善睡眠的作用。

Objective： To investigate the effects of electromyography （EMG） feedback and relaxation training on insomnia in college students. Methods： EMG feedback and relaxation training were used to treat 36 insomniacs, who completed the Self-Rating Anxiety Scale, Self-Rating Depression Scale, Pittsburgh Sleep Quality Index before and after the treatment. The myoelectricity, and polysomnography were also recorded before and after the treatment. Results： After EMG feedback and relaxation training , the insomnics had an improvement in sleep quality, expressed as shortened sleep latent period （ 32.9 ± 22. 6/85.7 ± 52.8, t = - 2.60, P = 0. 015 ） and awakening （ 1.8 ± 0.8/3.5 ± 1.5, t = - 2. 78, P = 0. 031 ） , and prolonged REM （ 78.7 ± 22. 9/42.5 ± 24. 5, t = 3.10, P = 0. 033 ） , stage-3 sleep and stage-4 sleep （ 56. 0 ± 39. 4/31.9 ± 26. 2, t = 2. 65, P = 0. 024 ） . The anxiety and depression symptoms showed obvious improvement （ 30. 9 ± 5.3/35.7 ± 5. 8, 40. 9 ± 8.6/43. 7 ± 6. 2 ; t = - 3.00, - 2. 97 ; P = 0. 027, 0. 016 ） . Myoelectricity was also significantly decreased （ 2. 6 ± 0. 9/0. 8 ± 0. 2, t = 3.75, P = 0. 017） . Conclusion： The electromyography feedback relaxation training can relax muscles and mind, and improve sleep quality.
