语言诱导与古琴音乐对原发性失眠症患者疗效的比较研究(摘要)
1 研究背景
原发性失眠症是睡眠障碍的常见类型之一,其发病率呈逐年上升趋势,并影
响着人们的的生活质量,据2004年报道美国的失眠发生率高达32-50%,英国
10-14%,日本20%,法国30%,我国在30%以上,50%的学生存在睡眠不足。据
2011年北京友谊医院中医科门诊人口调查,北京地区失眠症状病人躯体化、抑郁、
焦虑及偏执等因子得分均高于全国常模数,存在不同程度心理障碍。而香港卫生
署于2008年4月的调查,用电话访问了超过2000名在小区居住的年龄介乎18至64
岁人士,发现失眠患病率显著上升。据2010年中国睡眠研究会公布的最新睡眠调
查结果,中国成年人失眠发生率为38.2%,高于国外发达国家的失眠发生率。失
眠发病率呈逐年上升趋势,不断影响社会经济和人们的生活质量。睡眠作为人的
生命所必须的生理心理过程,是机体复原和整合的重要环节,事实上,失眠本身
能影响患者身心健康外,同时原发性失眠症亦是精神障碍(抑郁症、焦虑症、强
迫症、恐怖症、轻度认知障碍等)的一种先兆关联的症状与疾病,而预防失眠是
维护精神健康的重要把关。但患者往往早期求诊以躯体障碍失眠为主,而忽略不
同心理疾患潜复着,都会导致失眠。2004世界卫生组织的报告中,已经提及慢性
失眠是精神障碍原因之一,因此倡导预防精神障碍及各项慢性疾病的发生,当以
预防失眠为首要。
2 研究目的
在目前,原发性失眠症治疗的中医治疗方法主要有非药物治疗、心理治疗、
药物治疗、针灸治疗等。而西医治疗失眠主要是以服用安眠药物为主,服用安眠
药虽然有助于急性失眠患者,但停药后仍未能改善失眠问题,而且长期服用还会
产生一些副反应包括嗜睡,认知障碍,头晕,焦虑,健忘,和行为异常不稳定,
不但会对造血功能、肝肾功能、心血管与神经系统功能性影响,同时还会影响认
知功能。中医药治疗失眠的疗效是肯定的,但起效时间很慢,很难短期内改善患
者睡眠问题。失眠患者多伴有焦虑抑郁障碍,因其情绪变化较大,对于所服药物,
无论中药西药都缺乏足够的信心能够治好疾病,即使药物对其失眠症状有改善,
但失眠与心理障碍有一定的关系,病情易反复,药物的疗效大受影响。然而寻求
中国中医科学院 2009 级博士研究生学位论文
心理咨询费用一般比较昂贵,且失眠发病一般在夜间,如进行心理治疗上十分不
方便。因此,寻求更有效的非药物治疗失眠的辅助方法,改善原发性失眠症患者
心身双方面的症状,本研究期望为非药物治疗失眠症的基础治疗上提供新思路与
路径。
3 研究方法
3.1入组与疗法
将自愿参加本次研究的原发性失眠症患者 120 人,采用区组随机分组,根据
文献报道以及统计学上最小样本量要求,应用 SAS 9.2 统计软件 PROC PLAN 过
程语句, 将 120 名患者随机分为 4 组,其中对照组 30 人、语言诱导 30 人、语言
诱导和古琴音乐组 31 人、古琴音乐组 29 人。入组时登记相关信息并按产生的随
机分配表中的“入组序号”与患者就诊的先后顺序相对应,为患者分配随机号和治
疗组别。
3.1.1 语言诱导组(光盘 A)
治疗时段:利用TIP核心治疗技术之一“语言诱导”,当中包括情志疏导技术、
意想式脱敏疗法、意念植入性认知治疗和暗示诱导性想象疗法,使患者产生心身
放松与愉悦的感觉,每次语言诱导组听30分钟《语言诱导放松》光盘;由香港大
学行为健康教研中心催眠治疗师自行编录粤语版之光盘,针对香港人语言的特
点,采用粤语版语言诱导对香港地区原发性失眠症患者进行心理治疗, 同时把语
言诱导制作成光盘,让患者带回家中,每周用5天在家睡前听30分钟。
3.1.2 语言诱导和古琴音乐组(光盘 B)
治疗时段:语言诱导(30分钟) 伴古琴音乐背景,同时把粤语版语言诱导配
古琴音乐背景制作成光盘,让患者带回家中,每周用5天在家睡前听30分钟。
3.1.3 古琴音乐组(光盘 C)
治疗时段:古琴组则听古琴音乐光盘;曲目分别是五首节奏舒缓的《幽兰》、
《良宵引》、《平沙落雁》、《醉渔唱晚》和《忆故人》,音乐采用立体耳机播放。同
时把单纯古琴音乐制作成光盘,让患者带回家中,每周用5天在家睡前听30分钟。
3.1.4 对照组
治疗前 2 周和治疗期间,未使用过催眠药物(包括西药和中药)及其它精
神病药物者,也没有使用过任何辅助入睡的非药物疗法;在测试心率变异性和脑

电图过程的时候, 患者只保持在休息状态。
3.2 采用睡眠医学评价方法
采用阿森斯失眠量表(AIS)和症状自评量表(SCL-90)入组后第 0、2、4、
8 周观察记录各 1 次,患者前后的脑电图(EEG)、心率变异性生物反馈(HRV)入组
后第 0、4、8 周观察记录各 1 次,进行治疗前和治疗后疗效的比较。
3.3 疗程观察时间
观察8周。给患者发放相关光盘,在家睡前治疗,每周用5天睡前听30分钟。
确保失眠患者的依从性,首先是定期对患者进行心理沟通,每一周均要定期给每
位患者打电话,我们利用调查的问卷记录其依从性。 因此,提高患者对于原发
性失眠症治疗的愿望, 以保证患者的依从性。
4 研究结果
4.1 非药物疗法对失眠的改善
阿森斯失眠量表总分差值比较语言诱导组、古琴音乐组、语言诱导和古琴音
乐组相对于对照组,证明三种非药物疗法能够显着改善失眠较对照组为优。其中,
语言诱导和古琴音乐组对失眠的改善优于其他治疗组。
4.2 非药物疗法对 SCL-90 中症状的改善
与对照组相比,在第 4 周,三个治疗组在“恐怖”和“其它”因子上的平均差值
有显著的下降;在第 8 周,三个治疗组在“强迫”、“恐怖”和“其它”因子上的平
均差值有显著的下降。
4.3 非药物疗法对脑电图的改善
脑电图指标差值比较,在第 4、8 周,语言诱导组、古琴音乐组、语言诱导
和古琴音乐组、相对于对照组而言,Alpha 和 Theta 波有显著的增多,表明 Alpha
和 Theta 波的改变可能是三种疗法起作用的机制之一。
4.4 非药物疗法对心率变异性生物反馈的改善
语言诱导组、古琴音乐组、语言诱导和古琴音乐组、相对于对照组而言,
VLFper、LFper、LF/HF 以及 HR 有显著的降低;而 HFper 有显著的升高,可认
为三种治疗方法改善了失眠患者的心率变异性。
4.5 四种疗法治疗前后疗效指标的组内比较

较均有显着统计学差异,证明每一种非药物疗法是有疗效的。
5.讨论
5.1 心理机制
古琴音乐结合语言诱导的心理机制,主要从如下 4 方面剖析:
第一、从古琴音乐本身的机制来看,当古琴音乐播放出淡雅节奏、清和韵律、
优美旋律时,听众(病人)就容易进入一个放松的入静状态,并自然而然地产生
一种记忆过程,这也是一个使其慢慢熟悉了解古琴做为背景音乐的过程。
第二、当古琴音乐 CD 中的语言诱导开始播放时,病人一次次地听的过程会
加深对其内心的感受力、理解力、联想力等。随着听的次数增加,患者对古琴音
乐背景下的语言诱导的记忆,也就随之强化变成内隐记忆。在记忆、理解、联想、
推理等越来越深刻的基础上,病人不断加工的过程中,即是增加病人对睡眠与失
眠的合理认知过程,从而逐渐改善病人的不良情绪,所以,病人慢慢就会获得改
善失眠症的效果。
第三、内隐记忆中语言诱导的信息不断强化、升华的过程亦是作用于潜意识
的过程。每当病人失眠时大脑就可能自动闪回语言诱导的信息,从而能自主、自
发的调节睡眠认知与情绪,达到改善失眠症的效果。
第四、主动播放 CD 这个需求与行为对患者产生积极的自我效能,自主参与
治疗会增强病人对治疗过程的认知度、自信心,从而改善病人的不良情绪,有助
于患者心身两方面的调治与改善。
古琴音乐就是在放松身体、平静心情上起作用的,相当于改善患者的情绪状
态。语言诱导改变的是患者的(内隐)认知,所以语言诱导和古琴音乐组是同时
改变患者的情绪和认知,而其他组则是改变的一方面。所以在本研究结果显示:
语言诱导和古琴音乐组比其他组的效果好。
5.2 生理机制
本研究结果显示,治疗组在脑电图测量的大脑效应与使用脑电生物反馈已有
研究结论是一致。可能原因是: 因为人的脑波以及心脏的搏动存在着同步化的
节奏感。因为节奏一致,人在聆听悠然舒缓的古琴音乐,受到正面的语言诱导,
副交感神经就开始起作用,呼吸趋于平稳,中速的节奏与人的呼吸心跳同步速,
有助稳定心血流量,可诱导入睡。我们的实验研究结果提示,心率变异性(HRV)
和脑电波中α波和θ波可能存在某种程度的同步化 (Coherence),即心率变异性
曲线平滑如正弦波,这主要发生于心率变异性的低频段 (0.04−0.15 Hz),是心理
生理进入和谐状态的标志,这个心律模式就叫做心律和谐。心律和谐状态下,副
交感神经的活动也增强,身体系统以自然的频率共振 (0.1 Hz),促进了神经系统
和心脑动态交互的和谐性增强。和谐是一种积极的情绪状态; 心理上和谐是平
静、平衡、充满能量的状态,继而诱导出精神敏锐、集中精力和协调功能。
6. 研究结论
语言诱导、古琴音乐、语言诱导和古琴音乐治疗原发性失眠症,能够显著改
善患者的失眠以及严重程度,缓解与之相关的“强迫”、“恐怖”和“其它”等症
状,同时改善心率变异性生物反馈指标,并提高了脑电中Alpha和Theta波。本研
究应用我国的中医心理技术和古琴音乐在原发性失眠症上取得较好的疗效。其
中,语言诱导和古琴音乐组的疗效是最好,古琴音乐可使失眠症患者身心进入和
谐、安静、放松的状态,有效促进身心和谐、改善失眠,且古琴音乐在心率变异
性的低频段所诱发的合一性,进一步促进身心和谐,以及缓解其心理紊乱等症状;
语言诱导改变的是患者的内隐认知,所以,语言诱导和古琴音乐组是同时改变患
者的情绪和认知。因此,将古琴音乐与中医心理养生结合起来,开发有针对性的
功能型音乐产品,可促进音乐治疗在精神心理康复中的应用,广泛应用于临床治
疗及养生保健,并可帮助失眠者缓减对安眠药的依赖性,从而提高失眠症患者的
康复效果,为非药物治疗失眠症提供新思路与路径。

Abstract
1. Background:
Over all kinds of sleep disorders, Primary Insomnia is one of the most common. Its
tendency of gradual increase in recent years, is causing negative impact on the quality
of life. According to a reporting in year of 2004, insomnia incidence rate is as high as
32-50% in the United States, Britain 10-14%, Japan 20%, France 30% and above 30%
in China, 50% of the students in China are lack of sleep. According to Beijing
Friendship Hospital outpatient population survey in 2011, the somatization, depression,
anxiety and insomnia paranoid factor scores of patients in Beijing were higher than the
modulus, often there are different degree of psychological barriers. And Hong Kong
Department of Health in April 2008 using the telephone access to more than 2000
people living in the community of aged 18 to 64, found that insomnia prevalence
increased significantly. According to the latest Chinese society for the study of sleep
survey in 2010, Chinese adults insomnia incidence was 38.2%, higher than which in the
developed countries. There is an upward trend in incidence of insomnia, and constantly
affects the social economy and people's quality of life. Sleep, as a necessity to man's life
of physiological and psychological process, is an important part of the body recovery
and integration. In fact, except that insomnia itself can affect patients' physical and
mental health, primary insomnia is also an aura symptom associated with mental
disorders such as depression, anxiety disorder, obsessive-compulsive disorder, phobias,
mild cognitive impairment, etc., and to prevent insomnia is important to maintain the
mental health. But patients with insomnia of early consultation often concentrate in
body disorders with insomnia, and ignore the different latent after the mental disorders,
which can cause insomnia. According to the World Health Organization report in 2004,
one reason of mental disorder is chronic insomnia, therefore advocating to prevent
insomnia is crucial to prevent mental disorders and chronic diseases.
2. Research objectives:
At present, primary insomnia can be treated by TCM non-drug method,
psychological method, acupuncture, or medication. The main therapy of insomnia in
western medicine is sleeping drugs. Drug medication is efficient in treating insomnia
but most sleep-inducement drugs cause undesirable resistance and dependency.
Taking sleeping pills can help patients with acute insomnia, but fail to deal with
insomnia problems after the drug was stopped, and long-term usage will produce
some side effects including drowsiness, cognitive impairment, dizziness, anxiety,
forgetful, and unstable behavior, which not only has influence on hematopoietic
function, liver and kidney function, cardiovascular and neurological functional, but
also can affect the cognitive functions. The curative effect of traditional Chinese
medicine treatment of insomnia is sure, but the work time is slow, and it is difficult to
improve the sleep problems in the short term. Because the insomnia patients are often
complicated by anxiety or depression, to take drugs, both Chinese traditional medicine
and western medicine are lack of enough confidence because the change of mood is
bigger. Even symptoms of insomnia have been improved by drugs, but there is a
chance that illness repeats because that insomnia has a certain relationship with
psychological barriers, which influences the curative effect of drugs. To seek
psychological counseling is generally expensive, as the insomnia after happen in the
night, psychological therapy is very inconvenient. Therefore, in order to look for more
effective auxiliary method of non-drug treatment of insomnia, improving
psychosomatic symptom in patients with primary insomnia, this study provided a
contrastive idea and paved way for new possibilities of using non-drug treatment for
primary insomnia.
3.Research Method:
3.1 Group and therapy
120 patients with primary insomnia who voluntarily participate in the study were
groupd by block randomize. According to a literatures and statistics on the minimum
sample size requirements, PROCPLAN process statements in SAS9.2 statistical
software were divide the 120 patients into groups randomly for different treatments
(30 in Contral Group, 30 in Hypnotic Suggestion Group, 31 in Hypnotic Suggestion
combined with Guqin Group, 29 in Guqin Group) Related data were recorded and a
“Group item number” was assigned to match with the order of patients receiving
treatment.

3.1.1 Hypnotic suggestion group (CD-A)
Treatment time: using one of the TIP core treatment technology " Hypnotic
suggestion ", including channel of modern technology, the intention of desensitization
therapy, implantable mind cognitive therapy and suggestion induced imagine therapy,
make the patients to relax and pleasure, listening to the language induced relaxation
CD for30 minutes one time; hypnotic therapists in Behavioral Health Research Centre
at the university of Hong Kong, cataloged the Cantonese version of the CD,
According to the characteristics of the Hong Kong local language, using the
Cantonese version, induced therapy to the patients with primary insomnia in Hong
Kong for five days a week at home before going to bed.
3.1.2 Hypnotic suggestion and Guqin music group (CD-B)
Treatment time: The Cantonese version of language induction with Guqin music
background is made into CD, which patients take back to their home, and listen to for
30 minutes one day, for five days a week before going to bed.
3.1.3 Guqin music group (CD-C)
Treatment time: patients in the Guqin group listen to Guqin music CD; Songs are
five slow songs such as "you lan", "liang xiao yin", "ping sha luo yan", "yi gu ren"
and "zui yu chang wan". Music is played with stereo headphones. Patients take the
simple Guqin music CD back to their home, and listen to the CD for 30 minutes one
day, for five days a week at home before going to bed.
3.1.4 The control group
Without using any sleep medication (including western medicine and traditional
Chinese medicine)and mental pill two weeks before treatment , without using any
auxiliary sleep non-drug therapy. In the test process of heart rate variability and EEG,
patients only stay in a resting state.
3.2 Adoption of assessment method in Sleep Medicine :
Using Athens insomnia scale and SCL-90 were used in weeks 0, 2 th, 4 th, 8th.
Data of EEG, HRV were recorded once a weeks in 0, 4th, 8th, for comparing of pre-
and post- treatment efficacy.
3.3 Duration of Observation time:
Patient were observed for 8 th weeks, CD were released to the patient for them at
home bedtime treatment. In order to ensure of compliance of insomnia patient, we
follow up with phone call once a week for all patients, and we use questionnaire to
record their compliance. Therefore, we improve patient’s desire for treating insomnia
and ensure their compliance.
4. Research Results
4.1. Improvements of non-drug treatment for insomnia
When “total scores” on the Athens Insomnia scale were compared, a significant
decline in the Hypnotic Suggestion Group, Guqin Music Group and combination of
Hypnotic Suggestion with Guqin Music Group was indicated than the Control Group.
This proved that the three non-drug therapies can significantly improve insomnia
symptoms. Overall, The combination of Hypnotic Suggestion with Guqin Music
Group was the best group comparing with the other groups.
4.2 Improvements of non-drug treatments in the self-reporting Inventory
(SCL-90)
When “Self-reporting Inventory” was compared in the 4th weeks, the Hypnotic
Suggestion Group, Guqin Music Group and combination of Hypnotic Suggestion with
Guqin Music Group all indicated a bigger decline on the average value of “Terror”
and “Others” than that of the Control Group. In the 4th and 8th weeks, the Hypnotic
Suggestion Group, Guqin Music Group and combination of Hypnotic Suggestion with
Guqin Music Group all indicated a bigger decline on the average value of
“Obsessive-compulsive”, “Terror” and “Others” than that of the Control Group.
4.3 Improvement of non-drug treatments in EEG
When EEG measurements were compared in the 4th and 8th weeks, the Hypnotic
Suggestion Group, Guqin Music Group and combination of Hypnotic Suggestion with
Guqin Music Group showed significant difference in Alpha and Theta waves from
that of the Control Group. This result illustrated that significant increase of Alpha and
Theta wave may be one of mechanism underlying effects of the three therapies.
4.4 Improvement of non-drug treatments in HRV
When measurements of the HRV index were taken in the 4th week, the Hypnotic
Suggestion Group, Guqin Music Group and Hypnotic Suggestion with Guqin Music
Group showed significant decrease in Percentage Very Low Frequency (VLFper),
Percentage Low Frequency (LFper), Low frequency/High frequency (LF/HF) and
heart rate (HR) than that of the Control Group. However, Percentage High Frequency
(HFper) significantly increased in the three therapy groups. This result proved that
these three non-drug therapies can significantly improve some of the HRV index.

4.5 Group comparison of treatment effects in the 3 groups using therapeutic
methods
When Athens insomnia scale (AIS), Self-reporting Inventory (SCL-90), EEG
and HRV index were compared in the 3 groups using therapeutic methods, i.e. the
Hypnotic Suggestion Group, Guqin Music Group and combination of Hypnotic
Suggestion with Guqin Music Group, data from pre and post intervention showed
statistical differences. These results indicated that each of the three therapies offered
effective treatment for primary insomnia.
5. Discussion
5.1 Psychological mechanism
The psychological mechanism of combination of Hypnotic Suggestion with
Guqin Music Group can mainly stated from the following four aspects:
First, from the perspective of the mechanism of harp music itself, when the
Guqin music broadcast an elegant rhythm, the audience (patient) is easy to enter a
relaxation of the static state, and automatically generate a process of memory. This is
a process of making patients gradually familiar with Guqin as background music.
Second, when the combination of Hypnotic Suggestion with Guqin Music CD
began to broadcast, patients listened to the Hypnotic Suggestion process again and
again, which will deepen the inner sensibility, understanding, suggestion and so on.
As listening time increases, memory of patients about the induced language was
strengthened into implicit memory. On the basis of understanding, suggestion,
reasoning more and more deepened, the patient will get deeper understanding of the
rational cognitive processes of sleep and insomnia, so as to gradually improve the
patient's bad mood, and the effect of treatment will be slowly improved.
Third, induced by the language, implicit memory information unceasingly
strengthens, and the sublimation process also takes parts in the process of the
subconscious. Whenever insomnia occurs, the patients` brain will automatically
flashback language information, so that adjusting the sleep independent, spontaneous
cognition and mood, which will improve the effect of treatment.
Fourth, the demand and behavior of playing CD actively have a positive
self-efficacy of the patients. The participation in treatment can enhance the
recognition and self-confidence of patients, thus improving the unhealthy feelings of
the patients, helping patients with psychosomatic aspects of modulation.
Guqin music is to play a role on body relaxing and mood calming, equivalent to
improve the patient's emotional state. Hypnotic Suggestion change the cognition of
patients, so patients in combination Hypnotic Suggestion and Guqin music group are
changed in the emotional and cognition at the same time, while other groups are partly
changed. So this study shows: the curative effect for combination of Hypnotic
Suggestion and Guqin music group is better than other groups.
5.2 physiological mechanism
According to the results, the treatment groups have effect on EEG measuring
brains as same as using EEG as biofeedback in existing research. Possible reason is
both people's brain waves and pulsation of the heart has a synchronized rhythm.
Because the pace is consistent, when people listening to soothing Guqin music or
induced by positive language, parasympathetic nerve began to play a role, breathing
become steady, medium speed of the rhythm keeps up with breathing and heartbeat
synchronous speed, helping people with stabilize blood flow, which can induce to
asleep. The experimental results suggest that heart rate variability (HRV) and EEG
alpha and theta may be some degree of synchronization (Coherence), namely the heart
rate variability curve shows smoothing like the sine wave, which mainly happens on
the very low frequency band (0.04-0.15 Hz) of heart rate variability, as a sign of
psychological physiology entered into a state of harmony. And this rhythm of the
heart pattern is called the heart rhythm harmony. Under the harmonious state, the
parasympathetic nerve activity also increases, the body system resonances with
natural frequency (0.1 Hz), promotes harmony between the nervous system and
enhancement of dynamic interaction. Harmony is a state of positive emotions.
Psychological harmony is a state of calm, balanced and full of energy, which in turn
induce mental acuity, focus and coordination functions.
5. Research Conclusions
Hypnotic Suggestion, Guqin Music and combination of Hypnotic Suggestion with
Guqin Music can improve primary Insomnia symptoms and relieve associated
“Obsessive-compulsive”, “Terror” and “Other” symptoms. Moreover, some of the
HRV index and Alpha and Theta wave in EEG were improved in the three therapies
groups. Significant effect was observed applying TCM psychology and Guqin Music
Therapy for Primary Insomnia. Meanwhile, the effect in combination of Hypnotic
Suggestion with Guqin Music group was the best one. Guqin Music can make
Insomnia patients’ body and mind into a state of harmonious, quiet and relaxation,
which can effectively promote the harmony of body and mind, so as to improve the
insomnia symptom. At the same time, Guqin Music can caused a kind of unique of the
low frequency heart rate variability, to further promote the harmony of body and mind,
and relieve the psychological disorders as well as other symptoms. The purpose of
language is to change patients implicit cognition, so combination of Hypnotic
Suggestion with Guqin Music group is changing both patients' emotion and cognition.
Therefore, to combine Guqin Music with TCM psychological health therapy, develop
targeted and functional music product can promote the application of music therapy
on mental rehabilitation, be widely used in clinical treatment and health care, and ease
reliance on sleeping pills, so as to improve the rehabilitation effect of patients with
Insomnia, provide new idea and method for non-drug treatments of primary insomnia.
