The Study of Improvement of sleeping pattern by Relaxation method (progressive muscle relaxation)

本研究的目的是通过分析渐进式肌肉放松技术带来的生理和感觉反应来检验渐进式肌肉放松（PMR）的效果；并通过分析病例报告来考虑PMR技术在临床中的应用，以改善睡眠模式的质量。在初步研究中，我们对23名健康年轻人（平均年龄20.8岁）进行了PMR诱发的放松反应检测。评估项目包括心率变异性（HRV）、脑电图（EEG）、肌肉松弛感觉量表和Spilberger状态-特质焦虑量表（STAI）。结果显示实验组（PMR） RR间期延长和CVrr升高明显高于对照组（卧床休息组）。实验组表现为短暂性LF/HF升高后立即下降，提示交感神经加速的反映。脑电图结果显示α、β波减少，θ波增加。主观反应量表在肌肉放松感觉知觉方面也有较大的提高，焦虑量表得分则有所下降。因此，PMR技术可以获得有效的弛豫反应。采用相同的PMR方法，对56例住院患者（对照组30例，平均年龄59.4岁；实验组26例，平均年龄57.2岁）的睡眠模式质量改善情况进行分析。所有的样本都是癌症患者。评价指标采用睡眠评价问卷（SEQ）、睡眠量表（STAI）和自由书写自我报告。结果显示，睡眠模式在数量上没有变化，但入睡速度快，睡眠中断后容易入睡，醒来时身心平衡感增强。夜间醒来的频率因样本而异；在某些情况下减少，而在其他情况下没有变化或增加。他们受症状的影响很大，症状是对治疗和检查的反应。初步研究和临床研究都是在获得样本知情同意后进行的。泛化有一些局限性，但我们可以提出通过使用放松技术来改善睡眠模式质量的可能性。我们期待着对该技术临床应用方法的进一步研究和发展。少

The purpose of this study were to examine the effects of progressive muscle relaxation (PMR) by analyzing physiological and sensory responses which brought up by this relaxation technique ; and to consider the clinical use of the PMR technique by analyzing case reports which improved the quality of sleeping pattern.In the preliminary study, we examined the relaxation responses, which was brought up by the PMR, on 23 healthy young adults (average age was 20.8). Items for evaluation of responses were heart rate variability (HRV), EEG, muscle relaxation sensory scale and Spilberger's State Trait Anxiety Inventory (STAI). The result revealed greater prolongation of the RR interval and the elevation of CVrr in the experimental group (PMR) than the control group (rest in bed group). The experimental group showed the momentary elevation of LF/HF followed by immediate drop that suggested the reflection of accelerated sympathetic nerve. In EEG, the result showed decrease in α, β wave and increa … More se in θ wave. Subjective responses scale also showed greater increase in muscle relaxation sensory perception and decreased in anxiety scale scores among experimental group. There for, it was suggested that the PMR technique could get the effective relaxation responses.Using the same PMR method, we analyzed the improvement of quality in sleeping pattern for 56 hospitalized patients (sample size of the control group was 30, average age of 59.4 ; and the experimental group was 26, average age of 57.2). All samples were cancer patients. For evaluation index we used the sleep evaluation questionnaire (SEQ) and the STAI and the free writing self-reports. As a result, there were no quantity change in sleeping pattern, but they showed quickness in falling to sleep, easiness in sleeping after interruption, and increased sense of balance in body and mind on awakening. Frequency of awakening during nights varied among samples ; decreased in some cases and no changed or increased in others. They were greatly influenced by symptoms, which were responses of treatments and examinations.Both the preliminary study and the clinical study were conducted after getting informed consents from samples. There are some limitations in generalization, but we can suggest the possibility of improvement in quality of the sleeping pattern by using relaxation technique. We expect the follow-up survey and development of the clinical application methods of this technique. Less
