It is a descriptive cross-sectional study investigating the painful conditions for which Chinese consult an acupuncturist. The effectiveness of acupuncture as an analgesic was assessed subjectively using a visual analogue scale to estimate the amount of pain before and after treatment. A significant improvement was seen following acupuncture. The patients' own views on the efficacy of acupuncture in controlling their pain were also noted: this resulted in a mean effectiveness rating of 74.4%. Key words Acupuncture, China, Pain relief, Student elective. Background In the 1970s, when acupuncture was rediscovered by the West, there were many anecdotal stories of dramatic success, but there were still many critics who tended to reject acupuncture entirely. Since then, an increasing amount of convincing evidence has emerged for the mechanism of acupuncture, especially with regard to analgesia: pain is perhaps the most common presenting symptom in clinical practice. There has been evidence suggesting that acupuncture is generally effective in treating chronic pain, helping from 55-85% of patients, which compares quite favourably with the effect of potent drugs (1). Nowadays, acupuncture in the UK is most widely used for analgesia, and there have been studies showing an overall rate of around 70% significant relief in general practice patients (2). Apart from being effective, it also has the advantage of being relatively cheap, as shown in studies of acupuncture in General Practice (3-5). Since I have always been intrigued by acupuncture, the elective period (6-10) in the 4th year of my medical studies gave me an excellent ACUPUNCTURE IN MEDICINE opportunity to explore it further, to see it in action and to investigate its effectiveness, especially with regard to its analgesic properties. Where better to carry this out than China? My placement was at the First Teaching Hospital of the Traditional Chinese Medical College in Tianjin. The town is by the Bohai Gulf in the eastern part of the North China Plain, not far from Beijing; it covers an area of 11,305 square kilometres and is home to some 9 million people. The hospital was established in 1954 and classified as a general traditional Chinese medicine (TCM) hospital, but it combines traditional with Western medicine, having a variety of technical diagnostic and treatment aids such as: MRI and CT scanners, artificial kidney colour ultrasonography, dynamic ECG, Hyperbaric oxygen chamber, PCR quantitative analyser, and ultrasonic Doppler system. There are 900 beds and more than 600 outpatients a day in 25 out-patient clinics. There are 26 clinical and technical departments including: Acupuncture and Moxibustion, Internal Medicine, Surgery, Emergency, TCM Psychosomatic, International Convalescent, Paediatric, Orthopaedic, Ophthalmology, Pharmacy, etc. The hospital has been awarded prizes at national and local levels and has obtained significant achievements in scientific research. As an appointed teaching hospital for undergraduate and postgraduate education, students are admitted from all over China and from more than 40 other countries; an international school of traditional Chinese medicine is planned. At first, I found the language barrier was very much a problem, but the environment and the friendliness of the Chinese people, together with a little will-power, made it easier. It was only when I was able to communicate with the people that I could begin to learn what the indigenous Chinese are like and appreciate their culture. I had to learn the need for respecting elders when speaking. For example, there are several ways of asking a person's age. One way is for speaking to someone who is younger than yourself, while the other is the polite 101 Downloaded from aim.bmj.com on June 15, 2014 - Published by group.bmj.com DECEMBER 1999 VOL 17 (2) and respectful way to ask someone who is older. If one is ignorant of this custom, it is easy to give offence and break the trusting relationship between interviewer and patient. Introduction It has been said that Western students who wish to study traditional acupuncture must forget their Western ideas, as Chinese medicine holds little for the analytic mind to grasp! This is because it is based on holistic patterns, causal relationships, nonlinear logic, non-reductionistic views and empirical evidence. According to the theories of TCM, diseases, including pain, result mainly from relative imbalance of yin and yang: yang in excess or deficiency or yin in excess or deficiency. Needling specific acupoints can, according to TCM theory, return the yin-yang balance to equilibrium by unblocking stagnant qi to restore its flow around the meridians (11-12). As expected, the contrasting Western scientific model is quite different. Since the proposal of the gate control theory by Melzack and Wall in 1965 (13) and the discovery of stereo-specific opioid receptors and the endogenous opioid peptides in the 1970s (14), there has been an increasing knowledge of pain pathways and mechanisms, especially regarding acupuncture analgesia. It has been suggested that the analgesic effect can be mediated through the gate mechanism via endorphinergic interneurons releasing enkephalin or dynorphin and it has been postulated that endogenous opioids and monoamines secreted from the periaqueductal gray and the raphe nucleus in the mid-brain also play a role (15-17). Acupuncture has many applications in medical practice (18), but pain seems to be the area on which most research has focused. Macdonald et al (19) and Petrie et al (20) have shown a 55-85% effective rate for acupuncture groups in the treatment of chronic pain compared to a 30-35% rate for placebo controls. Molsberger et al (21) and Haker et al (22) have also demonstrated the effectiveness of acupuncture over placebo for treating the pain of lateral epicondylitis. In a study conducted by a medical student during her elective in Xi'an, China, a beneficial outcome was reported with acupuncture for chronic pain (8). Indeed acupuncture consistently shows a beneficial outcome and appears to help between 45% and 80% of painful conditions such as musculoskeletal pain, back pain and migraine, often with additional benefits such as an improved sleeping pattern and appetite, and relief from muscle spasm (23-28). 102 However, randomised, double-blind, controlled clinical trials in acupuncture remain difficult to design (29). This study was to look at the range and incidence of conditions with which patients present at the acupuncture clinic of a Chinese TCM teaching hospital, to correlate these conditions with the demographic details of the patients, and to investigate the effectiveness of acupuncture and related techniques in pain control. I had prepared a protocol for this investigation before leaving England, but when I arrived in Tianjin I found that the organisation of the acupuncture clinic made it impossible to carry out the protocol as planned. Specifically, there was no separate new patient clinic or follow-up clinic, so amendments were made to suit the circumstances and to allow me to follow the maximum number of patients throughout my stay. Method This descriptive, population-based study was conducted over a 5 week period in which 43 patients were studied in detail: 23 female and 20 male, with an age range of 28 to 74 years. To minimise bias due to the variability of the acupuncturist's skill, all the data was collected at one clinic only where the treatment was given by the senior acupuncturist or by one of her assistants under supervision. All patients who came to the clinic within the study period with a painful condition and received acupuncture treatment were interviewed by the author (Plate 1). Their demographic details were noted: age, sex, mode of referral and occupation. The type of painful condition was recorded together with its severity, expressed as a visual analogue score (VAS) that was completed by the patient before starting treatment and after completion of the acupuncture course. The VAS was an unmarked 5cm line with 0 meaning completely pain-free and 5 being the most pain Plate 1. Patients in the Acupuncture Clinic.

A course of acupuncture lasted 14 days, with daily sessions of 20 minutes each: this pattern of treatment was specified by the senior clinic doctor, Dr Yan. If the condition was chronic and further treatment was deemed necessary, it would be continued on a daily basis. Unfortunately, collection of data was bounded by the length of my elective period and thus in some cases was necessary before completion of a course of treatment. Data from patients undergoing a prolonged course of treatment was collected at the end of their course, however long it had continued. After each patient had completed a course of acupuncture treatment, the pain level VAS was recorded and the subjective effectiveness of acupuncture was assessed by asking patients to Table 1 SUBJECTIVE SCORING SYSTEM FOR THE EFFECTIVENESS OF ACUPUNCTURE 0 = Completely non-effective 1 = Very slightly effective 2 = Slightly effective 3 = Moderately effective 4 = Very effective 5 = Most effective Table 2 ACUPOINT SELECTION FOR PAIN RELIEF Low back pain radiating to the legs Dachangshu (BL.25), Zhibian (BL.54), Chengfu (BL.36), Yinmen (BL.37), Weizhong (BL.40), Chengshan (BL.57), Yanglingquan (GB.34) Lumbar back pain Qihaishu (BL.24), Dachangshu (BL.25), Guanyuanshu (BL.26), Shangliao (BL.31), Ciliao (BL.32), Zhongliao (BL.33), Xialiao (BL.34) Shoulder pain Yanglingquan (GB.34) Tension headache Quchi (LI.11), Taiyang (EX-HN5) Trigeminal neuralgia Sibai (ST.2), Quanliao (SI.18), Juliao (ST.3), Hegu (LI.4), Neiting (ST.44) Neuro-vascular headache Taiyang (EX-HN5), Yintang (EX-HN3), Shangxing (GV.23), Baihui (GV.20), Neiguan (PC.6), Hegu (LI.4), Sanyinjiao (SP.6), Taichong (LR.3), Fengchi (GB.20), Wangu (GB.12) Additional points may be selected on an individual basis.

This was done in a neutral manner to reduce the potential for interviewer bias, away from the acupuncturist and attempting not to give any impression that a particular answer was either hoped for or expected. Patients were assisted in scoring by being asked to think about their capability of coping with the activities of daily living, for example: washing, dressing, cooking, shopping and so on. For those patients who had already commenced acupuncture treatment before I was able to start recording, the initial condition was assessed retrospectively. At the acupuncture clinic, new patients were assessed by the acupuncturist in charge. This involved a thorough history and examination, together with a pulse and tongue diagnosis (Plate 2). She would then decide the appropriateness of acupuncture as a form of treatment and, if suitable, the mode of treatment and its length. There is a standard pattern of acupoint selection at the clinic for treating specific diseases (Table 2). Apart from point selection, the mode of treatment also varied, for example moxibustion was used in so-called cold syndrome. The other related forms of treatment used in combination with the acupuncture were: electrical stimulation of the needles, cupping, moxibustion to the needles, moxibustion on ginger or garlic, and acupuncture with a heat lamp (Plates 3-4). The mode of treatment varied between patients, with no specific pattern between the mode of treatment and the condition treated. There are many different needling methods, for example: twisting and rotating, or lifting and thrusting, each with a different speed of application. The needle size was also varied in needling different parts of the body. These variations were all noted as data for the study. Results Over the six weeks of the elective period, a total of 106 patients presented at the acupuncture clinic: 47 (44.3%) female and 59 (55.7%) male. The mean 103 Downloaded from aim.bmj.com on June 15, 2014 - Published by group.bmj.com DECEMBER 1999 VOL 17 (2) Plate 3. Acupuncture and moxibustion with garlic for headache. Plate 4.

A variety of conditions was seen, but mainly stroke (37.7%), for which acupuncture was used as a symptomatic treatment to relieve weakness or paralysis of limbs, and painful problems (37.7%) (Table 3). Out of the total seen, 43 patients had painful conditions (23 female and 20 male). The largest age group seen with pain was between 31 and 40 years, with the second largest being between 61 and 70. Their mean age was 51.9 years. In the pain group 2 patients each complained of two ailments: headache with low back pain, and headache with post-stroke shoulder pain. The patients were given separate acupuncture prescriptions for each ailment, although there was some overlap in the points used, thus the number of conditions reported was 45. Three patients failed to attend for their full course of treatment, so no postacupuncture assessment could be made for them. Of those whose data was complete, 8 others did not complete the full 14 day course of acupuncture before the end of my elective attachment, so the post-acupuncture assessment was carried out before I left Tianjin, but while their treatment course was still in progress. This might well have influenced the results, so the analysis has been repeated, excluding those 8 patients (Table 4). The mean VAS for pain pre-acupuncture is higher than that post-acupuncture for all conditions treated. The mean effectiveness ratings show a similar response ranging from 60% to 70% across all conditions except post-stroke shoulder pain Table 3 AGE DISTRIBUTION OF CLINIC PATIENTS SEEN WITH VARIOUS CONDITIONS Age n (%) Pain (%) Stroke Obesity Muscle spasm Numbness Arteritis Angina Palpitation Hypertension Dizziness Hydrocephalus Prostatitis Bell's palsy Dementia 21-30 4(3.8) 3(7.0) 0 0 0 1 0 0 0 0 0 0 0 0 0 31-40 21(19.8) 14(32.6) 2 1 1 3 1 0 0 0 0 0 0 0 0 41-50 14(13.2) 6(14.0) 7 0 1 1 0 0 0 0 0 0 0 1 0 51-60 20(18.9) 4(9.3) 9 0 0 1 0 1 0 2 3 0 1 1 0 61-70 30(28.3) 11(25.6) 15 0 0 1 0 1 1 1 1 1 0 0 0 71-80 16(15.1) 5(11.6) 9 0 0 0 0 1 0 1 0 0 0 0 1 >80 1(0.9) 0 1 0 0 0 0 0 0 0 0 0 0 0 0 Total(%) 106(100) 43(37.7) 43(37.7) 1(0.9) 2(1.8) 7(6.1) 1(0.9) 3(2.6) 1(0.9) 4(3.5) 4(3.5) 1(0.9) 1(0.9) 2(1.8) 1(0.9) The number of conditions exceeds the total number of patients (n) due to some patients having more than one condition. 104 ACUPUNCTURE IN MEDICINE Downloaded from aim.bmj.com on June 15, 2014 - Published by group.bmj.com DECEMBER 1999 VOL 17 (2) Table 4 MEAN VAS SCORE AND EFFECTIVENESS RATING FOR PAINFUL CONDITIONS TREATED Condition Musculoskeletal pain Low back Low back -> leg Arthritis Ankylosing spondylosis Post-stroke shoulder Headache Tension headache Migraine Trigeminal neuralgia Other Heartburn Total n(%) n (%) 9 (20.0) 9 (20.0) 8 (17.8) 1 (2.2) 6 (13.3) No exclusions VAS (pre) VAS (post) 3.5 1.8 4.5 2.5 4.1 2.2 3.0 2.0 4.4 1.4 Effect 3.2 3.4 3.2 3.5 3.8 With exclusions VAS (pre) VAS (post) 3.4 1.5 4.6 2.4 3.9 2.1 3.0 2.0 4.4 1.2 Effect 3.2 3.4 3.4 3.5 4.0 9 (20.0) 1 (2.2) 1 (2.2) 3.9 4.0 5.0 1.3 1.0 2.0 3.2 4.5 3.0 3.7 4.0 5.0 1.3 1.0 2.0 3.1 4.5 3.0 1 (2.2) 45 (100) 2.5 1.0 40 3.5 0 0 32 0 (pre) = pre-acupuncture, (post) = post-acupuncture, Effect = effectiveness rating (80%) and migraine (90%); however, there was only one patient with migraine. Thus, the results show an effective outcome for acupuncture treatment across the range of painful conditions studied. In poststroke shoulder pain the response could be seen immediately on needling the point GB.34 with most patients being able to rotate the shoulder with only slight pain. Nonetheless, the small sample size made analysis of individual types and positions of pain unreliable. The mean overall self-rated outcome of the effectiveness of acupuncture is 71.9%, with a standard deviation of 0.98. When those who did not complete the full course of treatment are excluded, the rating of the effectiveness of acupuncture is higher, although the sample size is reduced accordingly. This gives a mean for the patient rated effectiveness of acupuncture of 74.4%, with a standard deviation of 0.99. Discussion One of the objectives of the study was to find out the range and incidence of conditions with which patients present at a pain clinic in China. However, at the Tianjin hospital there was no specific pain clinic, since all clinics had a mixture of conditions. Nonetheless, the results show that the largest proportion of patients attending were those with pain or stroke, demonstrating that, as in most other countries, pain is a common problem for which patients go to see a doctor in China. That the number of stroke patients was large may be due to the huge number of smokers and heavy drinkers in China. Among the painful conditions seen, all were chronic, with musculoskeletal pain being the ACUPUNCTURE IN MEDICINE commonest of all across every age group (Plate 5). Within this category, low back pain with or without radiating pain to the leg contributed the largest number of patients. This was particularly true in the younger age groups. In the older patients, arthritis and post-stroke arm pain were the conditions more frequently seen. Headache was the next commonest condition, with tension headache being the most widely seen, again across all age groups (Plate 6). The largest number of patients attending the acupuncture clinic were those aged between 61 and 70 years; this could be because the elderly generally had more time, with the retiring age being 65 for males and 55 for females. Amongst those with painful conditions, the largest proportion were aged 21 to 30 years. This could be related to the cultural health belief that while they are still young, things are easily corrected, but if they just put up with pain, they would have a long hard life. Plate 5.

Most patients self-referred to the acupuncture clinic, and many chose the hospital owing to its excellent reputation, with recommendations from family, friends, work colleagues or through the media. There were occasional cases referred from the Western hospitals when the doctors there felt that acupuncture would be beneficial; both the cases I saw were of low back pain. For those patients suffering from stroke, most referrals were from the in-patient department at the hospital, where they would already have had a few sessions of acupuncture; these usually need long-term acupuncture treatment, mainly for symptomatic control. There was also a significant proportion of patients who had had unsuccessful treatment with Western medicine or had suffered side-effects from medication. Interestingly, most people believed that acupuncture therapy is free from side-effects, despite the medically known risk of hepatitis in China where hepatitis B is endemic. In view of this I noted that disposable needles were not used at the clinic and the method of sterilisation was soaking the needles in 70% alcohol for a few hours, after which they were reused. Also the acupuncturists dealt with needle injury merely by dabbing the puncture wound with alcohol or iodine. In addition, during my attachment at the hospital, there was no sharps-box and damaged needles were simply thrown away in the dustbin. In China, Western medicine is often used alongside acupuncture and it is generally agreed that the beneficial outcome of the combination of practices is substantial. At the hospital, the proportion of TCM and Western medicine is split in a ratio of 2:1. In the medical school, the main bulk of the curriculum is based on TCM theory, including pulse and tongue diagnosis, history of TCM, and TCM in the clinical specialties, for example: general medicine, general surgery, paediatrics and so on, in which acupuncture is only one part of the TCM teaching. The medical students are also taught the 106 basics of Western medicine, so after their 5 years at the medical school they can undergo further education in Western medicine. Nevertheless, many remain as TCM practitioners, but their knowledge in Western medicine enables them to practise using a mixture of both Chinese and Western theory, diagnosis and techniques. For example, CT scans and various imaging techniques, haematological and biochemical investigations, and Western pharmacology are integrated with TCM as part of the routine diagnosis and investigation of most patients. The main advantage of this system is that for conditions in which TCM practitioners recognise acupuncture therapy as non-beneficial, a rapid referral into a branch of Western medicine can be made at the diagnostic stage. It is generally believed that Western medicine is for acute conditions and minor illnesses like influenza, as it is thought to treat the surface of the disease. Therefore, people usually go to consult a TCM practitioner for chronic conditions, believing that TCM will treat the root of the problem. They also believe that TCM forms a good foundation for other medication, or interventions such as physiotherapy, to have an effect. Moreover, they consider that TCM plays a role in consolidating previous treatments so that health is maintained for a longer period of time. However, some people are unable to endure the discomfort of acupuncture, or they find TCM takes up too much time or is too expensive. For example, daily acupuncture treatment sessions may continue for 14 days, and the bitter herbal medicine has to be boiled for a long time, unlike Western medication which comes in tablet form. This partly explains the reason why Western medicine has become popular in China. Nonetheless, more people have come to appreciate the advantages and the disadvantages of each system, so that a combination of practice is the most favoured. I found it very difficult to assess the social class of patients, and talking to the people in China, I learnt that occupation does not offer a good estimate of social class. China is a communist country, implying that people's wages are more or less the same: about 300-500 yuan per month (£23-40), apart from professionals or government employees, whose salary may be higher: 700-1000 yuan per month (£54-77). People living in poverty will probably have 50-100 yuan per month (£4-8). Where a patient lives is a much better guide to social class. The majority of people live in rented flats as few can buy accommodation of their own, due to China's political system. As a rule of thumb, in a five storey block of flats: the 4th and 5th floors, with a view, are ACUPUNCTURE IN MEDICINE Downloaded from aim.bmj.com on June 15, 2014 - Published by group.bmj.com DECEMBER 1999 VOL 17 (2) usually the most expensive, the ground floor and the 1st floor are rented at medium price, and the 2nd and the 3rd floors are the cheapest. However, this system does not always hold true, leaving social class difficult to determine. Nonetheless, on observation, most patients who attended the acupuncture clinic were either middle or higher class due to the fact that acupuncture therapy was not affordable unless a patient had reasonable earnings or large savings. As to the effectiveness of acupuncture in treating chronic pain, the data show a promising figure of 74.4%. However, it must be noted that this was with subjective scoring. The visual analogue score of pain showed a significant decrease of pain postacupuncture, but again it was a subjective measurement. Hence, some possible confounding factors need to be discussed. It was generally felt that patients presenting themselves at the acupuncture clinic had a belief in TCM and an expectation that acupuncture would be successful, or they would have sought another form of treatment. From conversations with the local Chinese, I discovered that many had their own textbooks of TCM, so that when they fall ill they can self-diagnose and buy the appropriate medicine from the pharmacist. Some people would therefore already be taking Chinese herbal medicine, but may have denied this to avoid offending the doctor. The motivation to acquire basic TCM knowledge and the ability to self-treat may be due partly to the medical system in China. There is no national health service or equivalent in China; everyone, regardless of rich or poor, has to pay for their medical fees, which are relatively expensive. For instance, people need to pay 35 yuan (£3) to consult the acupuncturist. If further investigations are necessary, patients have to pay the additional fees. A further 200 yuan (£16) would be charged for each 14 session course of acupuncture therapy. If the condition requires electroacupuncture or moxibustion etc, the patient has to pay extra for these. The follow-up consultation costs another 35 to 50 yuan (£3-4). When converted to pounds sterling this may not seem expensive, however, due to the low earnings and low standard of living, the medical fees are a real burden for the local Chinese. Moreover, during the 14-day course of treatment, many had to take time off work and pay for their own transport (some came a long distance), and for some a single course of treatment may not be enough. Therefore, rather than spending money to see the doctor, they would prefer to try selftreatment first and consult the doctor only as a last resort. Consequently, late presentation is seen ACUPUNCTURE IN MEDICINE routinely in China and can sometimes lead to grave consequences. This private health care system in China might also have affected our results with regard to the effectiveness of acupuncture. It is possible that some patients decided to discontinue their treatment due to financial difficulties. Therefore, at the end of their course, they might have been unrealistically positive in terms of the effectiveness of acupuncture in order to avoid further costly treatment. At times during the interview one could sense a strong need in the patients to protect the reputation of one of the treasures of their country. For example, although they might admit that acupuncture did not seem to have had much effect, they would defend the method with suggestions as to why it might not have been effective for them: I'm too old; the disease is too chronic; I just need more sessions, or it's the weather. So, when asking for a subjective opinion on the effectiveness of acupuncture, subjective bias was inevitable. Understandably, the cultural influence plays a major role in the beliefs of patients and of some doctors, indeed some deny the need for evidencebased medicine, claiming that acupuncture works because thousands of years of experience have proved it. Under the influence of such strong cultural sway, there is very likely to be a placebo effect: the patient's beliefs and expectations of outcome influence the treatment. Furthermore, the doctor-patient relationship at the clinic was very paternalistic, so that the acupuncturist appeared to speak with great authority. Her words of encouragement and reassurance would have added significant weight to any placebo effect. The Plate 7.

It was found that a wide variety of conditions were treated with acupuncture, ranging from stroke to prostatitis. Amongst the painful conditions, chronic pain was predominant with musculoskeletal pain being the most common. The effectiveness was assessed subjectively in terms of a visual analogue score pre- and post-acupuncture, and by asking the patient to give a numeric effectiveness score. The results showed acupuncture and related techniques to be an effective treatment for chronic pain. Plate 8. Electroacupuncture for Bell's palsy. outcome of acupuncture treatment could have been influenced accordingly. There was no particular pattern to the mode of stimulation used. I learnt from the acupuncturist that the different modes had their unique properties and were used according to TCM theory and diagnosis, interpreted through the experience of the acupuncturist. The addition of moxibustion (30) (Plate 7) is used to warm the channel and expel cold, to induce the smooth flow of qi and blood, subdue swelling and disperse accumulation of pathogen; moxibustion with ginger is indicated in wind-cold syndrome, and moxibustion with garlic is for getting rid of toxins and drawing out pus. Cupping has the function of warming and promoting the free flow of qi and blood in the channels and dispelling cold and dampness. Electroacupuncture is used in numbness and neurological problems (Plate 8), and is also for muscular pain, when alternate current mode is the most effective because during stimulation the muscle contracts while in the absence of stimulation it relaxes; therefore, in effect, this process is equivalent to exercising the muscle. As it was not possible for me to interview all the patients at the beginning of their treatment since some had started before I had arrived, these patients were asked to rate retrospectively the severity of their painful condition before acupuncture therapy. This could have introduced errors through bias in recall. Other sources of error in the study were the small sample size, and the short period of follow-up, which was inadequate to assess the long term response to acupuncture in chronic pain. Conclusion This study was to record the conditions for which acupuncture is used in the out-patient department of 108 Plate 9. The clinic team with students.
