     Background 

    Fibromyalgia (FM) is diagnosed when a patient has

    pain in the axial skeleton, on both sides of the body

    and above and below the waist for three months or

    more, in combination with tenderness on pressure

    of 11 out of 18 specific tender points – the American

    College of Rheumatology (ACR) classification

    c rite ria fro m 1 99 0.1 Fib ro my algia is a

    polysymptomatic syndrome of chronic widespread

    pain often accompanied by fatigue, non-restorative

    sleep and visceral hyperalgesia. It is a common cause

    of chronic widespread pain,2 responsible for an

    estimated 10-20% of new patients attendingrheumatology clinics.3;4 T he s ymptoms o f  

    fibromyalgia can persist for many years and outcome

    is generally poor.5-7 Chronic ill-health and disability

    are well recognised consequences.8

    Currently available treatments are often

    ineffective. Amitriptyline has been shown to be

    effective in some but not all patients with

    fibromyalgia.9 Tramadol,10 either on its own or in

    combination with paracetamol,11 has been shown to

    be helpful in treating the pain of fibromyalgia. The

    evidence for lidocaine infusions alleviating

    fibromyalgia pain is equivocal.12 There is some

    evidence that N-methyl-D-aspartate (NMDA)

    antagonists, eg ketamine and dextromethorphan canameliorate the pain of fibromyalgia,13;14 and more

    Acupuncture in the treatment of fibromyalgia intertiary care  – a case series Barbara Duncan, Adrian White, Anisur Rahman

     Abstract

     Aims   Fibromyalgia is a common cause of chronic widespread pain. The benefit of medication is often

    limited by its side effects, and the improvements obtained with exercise and education are inconsistent.

    Many patients seek acupuncture treatment, which is reported to be helpful in some cases. This study aimed

    to explore the acceptability and benefits of acupuncture offered in the setting of a tertiary referral clinic.

     Methods   An open, uncontrolled observational study was conducted among patients who met the usual

    fibromyalgia criteria and who had a pain score of at least 30 on a 100mm Visual Analogue Scale (VAS).

    Patients were allowed to continue other treatments but not to introduce new ones. Acupuncture was given using

    a Western approach according to a protocol developed by consensus. Patients were offered eight treatments

    in eight weeks. Outcome measures included VAS of pain intensity and Fibromyalgia Impact Questionnaire

    (range 0 – 100), and were taken before and after treatment, and at 14, 20 and 34 weeks from enrolment.

     Results   Twenty four eligible patients were enrolled in a 12 month period. Baseline mean pain VAS score for

    these 24 patients was 74 (SD 18) and mean Fibromyalgia Impact Questionnaire score 78 (SD 12.4). Only 14

    patients completed the course of treatment within about 10 weeks. Compliance was poor in the remaining

    patients because of difficulty attending clinic, and in two cases because of exacerbation of pain. Completion

    of outcome measures was variable and therefore the analysis of data is limited. Five patients scored at least

    20% reduction in Fibromyalgia Impact Questionnaire score which is a clinically relevant improvement. Two

    of these scored at least 50% reduction.Conclusion  Acupuncture appears to offer symptomatic improvement to some patients with fibromyalgia

    in a tertiary clinic who have failed to respond to other treatments. In view of its safety, further acupuncture

    research is justified in this population.

    recent evidence supports the use of pregabalin,

    gabapentin and duloxetine.15 However, these

    medications have side effects that can make them

    intolerable to patients with fibromyalgia, who are

    often more sensitive to medication.16;17 Education

    and exercise have been shown to improve somesymptoms of fibromyalgia but results are

    inconsistent.17-19 Their beneficial effects depend on

    motivation and ability to comply with the exercise

    regime.

    Treatments that can minimise unpleasant

    symptoms (without troublesome side effects) and

    reduce the health and social burden of this disease

    would be welcome. Acupuncture has the attraction of 

    not being a pharmacological product consumed on a

    daily basis. Clinical observation suggests that

    acupuncture may be a viable adjunct in the

    management of fibromyalgia. Increased use of 

    acupuncture has been encouraged by the British

    Medical Association, while calling for better quality

    of evidence.20 However, there are limited resources

    for acupuncture in the NHS and it is important to

    use them efficiently, concentrating on conditions

    where the potential for benefit is based on best

    evidence.

    One third of the patients with fibromyalgia

    described by Ledingham had been treated with

    acupuncture, and 29% of these had found it helpful.8

    A recent review included five RCTs of acupuncture

    in fibromyalgia,21 and concluded that the evidence

    is mixed and that further rigorous studies seem

    warranted. They also noted that all the positive trials

    used electroacupuncture.

    The first author currently uses manual

    acupuncture (but not electroacupuncture) in this

    tertiary specialist pain clinic to treat patients with

    fibromyalgia. We originally planned to test the

    effectiveness of manual acupuncture in an RCT, andtherefore designed a feasibility study to provide us

    with information on which to base a subsequent grant

    application, and gained consent of The National

    Hospital for Neurology and Neurosurgery and

    Institute for Neurology Joint Research Ethics

    Committee. However, because of the difficulties we

    experienced, which we describe here, it seems

    unlikely that a definitive RCT would be funded in

    this setting.

    Therefore, our aim in this paper is to simply

    report the patients’ progress. The fact that we

    originally planned a pilot study explains certain

    features which might have been different in a case

    series, such as certain inclusion criteria, the restriction

    on using other interventions for the whole of the six

    months’ trial period, and the multiple outcome

    measures we used. However, we wish to report ourfindings out of recognition of the patients’

    commitment to the trial, and to add to the body of 

    evidence on what this type of acupuncture may

    achieve for patients with advanced fibromyalgia,

    and to provoke discussion on different treatment

    approaches.

     Methods

    An open, uncontrolled observational study was

    conducted among outpatients at the Centre for

    Rheumatology, University College London and the

    Pain Management Centre, University College

    London.

    Patients aged between 18 and 65 years with

    fibromyalgia, as defined by the ACR criteria,1 were

    recruited. Only patients who rated their pain level

    as 30 or higher on a 100mm Visual Analogue Scale

    (VAS) were included, as we judged this to be

    sufficient to demonstrate a reduction. Presence of a

    co-existing systemic rheumatological illness (such

    as systemic lupus erythematosus or Sjogren’s

    syndrome) was not an exclusion factor, since it has

    been shown that this does not affect the clinical

    characteristics of fibromyalgia.1

    Patients with clotting disorders were excluded, as

    were patients who had previously experienced

    acupuncture for fibromyalgia and those who did not

    wish to be given acupuncture.

    All regular medications were continued during

    the study period. Use of amitriptyline or any other

    drug prescribed for fibromyalgia or musculoskeletal

    pain was not an exclusion factor, provided the dosehad been stable for at least three months before

    entering the trial.

    Patients were excluded if they had started

    physiotherapy, psychology or education sessions

    within the last three months, and patients were asked

    not to start these forms of therapy during the treatment

    period or for a follow up period of three months.

    We aimed to recruit and treat 24 patients, which

    we calculated would be enough to identify a

    statistically significant response, eg a 20% reduction

    in pain intensity VAS (from 60 to 40).

    All patients presenting in clinic were assessed by

    AR or BD to confirm that they met the ACR criteria

    and the other inclusion criteria. They were then given

    an information sheet which explained the need to

    complete extra questionnaires and the possibility of 

    mild side effects including dizziness, drowsiness,headache, nausea, bruising and possible temporary

    worsening of pain.22 Patients declining to give consent

    were offered acupuncture in the usual way, outside

    the study.

     Acupuncture intervention

    All procedures were carried out by BD, who has been

    a member of the BMAS for six years and is a

    consultant pain specialist experienced in the use of 

    acupuncture for treating fibromyalgia, at the Pain

    Management Centre, National Hospital for Neurology

    and Neurosurgery. Treatment was carried out

    according to the usual practice there, ie using a

    Westernised approach to acupuncture, involving

    manual needling of trigger points, appropriate

    neurosegments and distant sites, depending on the

    locations of painful areas in the individual patient.

    Superficial needling with a small number of needles

    was used, because patients with fibromyalgia are

    often especially sensitive to needling.23 Superficial

    needling of the skin in people with fibromyalgia has

    been shown to produce an increase in skin and muscle

    blood flow not seen in healthy subjects.24 This

    supports the concept that light needling of the skin in

    fibromyalgia patients could produce the same effect

    as deeper intramuscular needling in normal subjects.

    The treatment protocol (see Appendix) was

    designed to be reproducible but allow flexibility. It

    was sent to six senior members of the British Medical

    Acupuncture Society for review, and modified in

    response to their comments; at least one commentator

    thought the duration of needling was excessive.Electroacupuncture was not recommended by any

    of the reviewers.

    The protocol specified that patients would be

    given eight treatments at weekly intervals. From

    clinical experience with fibromyalgia patients,

    improvement is commonly not seen until the fourth

    or fifth treatment, and BD routinely offers a

    maximum of 10 acupuncture treatments. Giving eight

    treatments was regarded as a reasonable compromise

    between the minimum necessary and the maximum

    possible within the limited resources of the Centre.

    At each appointment, patients were asked about the

    response to the previous treatment, and the sites and

    severity of pain were established in order to plan

    further treatment.

    Outcome measuresOutcome measures were collected on five occasions

    – immediately before treatment, at the end of the

    eight week treatment; then by post after six weeks (14

    weeks from randomisation) and three months (total

    20 weeks); and finally at a clinic visit after six months

    (total 34 weeks after enrolment).

    Outcome measures included the following: 1)

    VAS of pain intensity at that moment in time; 2) the

    Fibromyalgia Impact Questionnaire (FIQ), a validated

    20 item questionnaire which includes questions about

    work, ability to carry out everyday activities,

    tiredness, pain, stiffness and depression;25 with higher

    scores indicating greater impairment; 3) the Short-

    Form McGill Pain Questionnaire; 4) the Pain Self-

    Efficacy Questionnaire, where patients are asked to

    rate their confidence in performing various activities;

    5) the SF-36 (Short Form 36 Health Survey), in nine

    domains exploring physical, psychological and social

    aspects of the patient’s response, from which we

    analysed the physical and mental components; 6)

    the Hospital Anxiety and Depression scale; 7) a

    global assessment of change: ‘Please tick the box to

    show how you think your fibromyalgia is now,

    compared with before acupuncture’, offering a choice

    of five responses from ‘very much better’ to ‘very

    much worse’.

     Analysis

    The analysis was exploratory. Where data were

    missing for one or two time points, but present for a

    subsequent one, the value of the last reading was

    carried forward. Data were not carried forward formore than two missing time points, nor after patients

    had dropped out.

    It was not possible to give some patients weekly

    treatments because they attended so sporadically.

    Since a continuous course of treatment may be

    necessary for acupuncture to be effective, we decided,

    when looking at the results, to group patients and

    analyse results according to whether they had

    complied with regular appointments and received

    an appropriate course of acupuncture. Patients were

    placed into three groups. Group 1 included patients

    who completed the treatment protocol in or close to

    eight weeks. Group 2 included patients whose

    treatment was spread over time with intervals of 

    several weeks between treatments, for reasons

    relating to poor health or social circumstance. Patients

    who failed to complete treatment were placed ingroup 3 and not included in the main analysis.

     Results

    A total of 25 patients were enrolled between

    November 2003 and November 2004. One patient

    was subsequently excluded as her initial VAS score

    was too low, leaving 24 patients for analysis. Figure

    1 shows their flow through the study. Baseline pain

    VAS score for these 24 patients was 74 (SD 18) and

    FIQ score 78 (SD 12.4).

    Group 1 contained 14 patients, and Group 2 had 6

    patients. Reasons for failing to attend treatment

    regularly included disability from fibromyalgia and

    hospitalisation for severe depression. Four patients

    (Group 3) failed to complete the treatment protocol.

    Two of these experienced more severe pain followingacupuncture despite very light needling.

    In many cases there were considerable amounts

    of missing data. Nine patients had data missing at

    follow up of either 20 or 34 weeks, or both. There

    was a notably poor return of postal questionnaires.

    One patient who completed treatment per protocol

    did not complete any measures in a manner that could

    be used, and on the follow up visit her daughter was

    seen to be completing the VAS score. On two

    occasions, FIQ was not completed when other

    questionnaires were. Thus, of the 24 patients eligiblefor inclusion, 14 (60%) completed the treatment as

    per protocol but only five of these (20% of those

    enrolled) provided sufficient data for a complete

    evaluation.

    The socio-demographic and outcome data for

    the three groups are presented in Table 1. Group 1

    tended to be older than groups 2 and 3 and to take

    more medication for other medical conditions. There

    were no other meaningful differences between the

    groups All three groups had a median of two other

    significant medical conditions.

    Global scores were reported by four patients on atleast one occasion as ‘very much better’, all in

    Group 1. Only one patient still scored ‘very much

    better’ at 34 weeks, and this self assessment is

    consistent with her scores for other measures: for

    example, her FIQ fell from 60.5 to 20.6, and VAS

    7.1 to 0.3.

    The FIQ is regarded as the most valid measure of 

    overall impact of fibromyalgia, and individual scores

    of patients in Group 1 are shown in Figure 2. At the

    end of treatment three scored at least 20% reduction

    and two others at least 50% reduction. One patient

    still had 20% improvement at six months, and one

    still had greater than 50% reduction. The respondents

    were not different from non-respondents in either

    mean age (54 and 52 years respectively) or duration

    of symptoms (six and eight years respectively).

    Because of the amount of data that remained

    missing, even after substituting as described above,

    group analyses can be considered reliable only for 11

    patients at four weeks in Group 1, and only for five

    patients at three weeks in Group 2. There was a small

    but consistent reduction in group scores for all

    measures at the end of treatment in Group 1, ie the

    patients who received acupuncture as per protocol.This is shown for three outcomes in Table 2. No

    reduction was seen in any measure in Group 2. There

    was no suggestion of a continued effect in Group 1,

    as group scores for all measures returned to baseline

    values from week 14 onwards.An analysis of those

    eight patients who provided baseline and six month

    data showed no trend to any long term effect.

    Finally, for the remaining outcomes, results are

    presented from all patients who provided data up to

    the fourth data point (20 weeks), and are shown in

    Table 3.

     Discussion

    In this group of 24 patients with fibromyalgia referred

    to a tertiary pain clinic and willing to receive

    acupuncture in the context of a trial, acupuncture is

    of limited application mainly because repeated

    attendance at clinic can be a problem. In retrospect,

    the severity of the symptoms, using these outcome

    measures, would not have predicted difficulty with

    attendance. It may be more relevant that these people

    were living alone and did not have anyone to

    accompany or take them to clinic. Patients with

    fibromyalgia often complain about deterioration of 

    cognitive function. Park and colleagues demonstrateddeterioration of short term memory and deficits in

    vocabulary comparable to aging by 20 years.26 This

    may be relevant in attending outpatient appointments

    eg one patient described leaving home and not being

    able to remember where she was going – arriving

    for her appointment was a major achievement.

    Of the 14 patients who could attend for the course

    of treatment, about a third had measurable benefit

    of at least 20% reduction in the FIQ score, which is

    a clinically relevant improvement. Two of these

    patients had a greater than 50% improvement.

    However, our data do not provide any information on

    which patients respond best. We have no evidence

    that the likelihood that a patient will respond can be

    predicted from their age, severity or duration of 

    symptoms. The one patient who was excluded,

    because her VAS score was below 30, showedmarked improvement in other outcome measures.

    The presence of multiple pathology or use of other

    medications did not seem to prevent a response to

    acupuncture (though we cannot say whether or not

    these factors reduce the size of the response).

    Because we had no control group, we cannot

    draw any conclusions as to whether this response in

    some patients is a specific effect of needling.

     Acupuncture protocol

    A protocol for application of acupuncture was used

    to allow reproducibility of method. In practice some

    changes were necessary during the study. The overall

    number of needles allowed should be greater than

    10. The number was limited to 10 needles for this

    study to minimise the cost of placebo needles for a

    future RCT. Towards the end of the study, the

    protocol was modified to try to improve the response,

    and two patients had more than 10 of the smaller

    needles inserted – with benefit. It is possible that

    limiting the number of needles impaired the response

    to treatment. The use of electroacupuncture is

    discussed below.

    There is a wide spectrum of sensitivity to

    acupuncture in fibromyalgia. Some people respond

    to light superficial needling with a severe

    exacerbation of pain, whereas others improve with 20

    deep needles inserted intramuscularly, as was evident

    in this study. Currently, it is not possible to predict

    which people will require deep needling to produce

    a good response. Lundeberg and Lund’s recent article

    provides the neurophysiological basis for suggestingan approach that tries both ‘light’ and ‘strong’

    stimulation when performing acupuncture for patients

    with fibromyalgia, continuing with the more

    successful one.27 Three out of 25 patients had the

    larger (0.3mm diameter) needles inserted, contrary to

    the recommendation of Baldry,28,29 with good effect.

    The protocol also defined manual stimulation as

    rotation of the needles for five seconds every minute,

    which was difficult to reproduce precisely.

    A number of patients initially responded well to

    a gradual increase in the number of tender points

    needled, but reached an upper limit, above which

    the pain became worse. They were therefore treated

    with distal points instead, including LI4, LR3, ST36

    and SP6. Their response often improved with this

    approach, which was partially catered for in the

    protocol by allowing additional traditional points.The treatment protocol had not anticipated omitting

    tender point needling.

    Other studies of acupuncture for fibromyalgia

    Four RCTs in the Western literature provide findings

    that can be compared with our own. In three of these

    studies, the patients were clearly less severely affected

    than ours. Harris and colleagues explored three

    treatment variables – needling sites, needle

    stimulation, and dose of treatment – for pain in a

    crossover study in 114 patients recruited through the

    media, with average baseline VAS of about 55. They

    found only an overall dose effect of manual

    acupuncture. 30 Deluze and colleagues, in patients

    recruited after referral to a rehabilitation clinic with

    baseline VAS of about 60, found electroacupuncture

    significantly more effective than a minimally active

    control treatment, for several outcome variables.31

    Martin and colleagues compared acupuncture with a

    non-penetrating sham acupuncture in a rigorous RCT

    in 50 patients with fibromyalgia; the acupuncture

    group showed significantly greater improvement in

    symptoms measured by the Fibromyalgia Impact

    Questionnaire, particularly fatigue and anxiety.32 The

    benefits were still present, though reduced, after seven

    months. Baseline FIQ scores of around 43 indicate

    that the patients were less severely affected than ours.

    In another study, Assefi and colleagues recruited

    patients through media and healthcare providers,

    with a mean pain intensity VAS score of 7 on a 10cm

    scale.33 A course of 12 sessions of a specific manual

    acupuncture prescription in 100 patients was no betterat reducing pain than the pooled results from three

    control interventions: acupuncture for a different

    condition; non-point acupuncture; and a non-

    penetrating control. There were trends towards

    differences between the control interventions, but

    these were not commented on by the authors. The

    trial was no doubt under powered to show a

    difference between a specific form of needling, and

    a combination of other varieties of needling.

    Only one of the reports of these studies gives an

    estimate of the percentage of responders (as well as

    group mean scores). Deluze reported that about half 

    his patients in the acupuncture group ‘improved

    satisfactorily’, a quarter showed no change, and a

    quarter showed ‘an unexpectedly large improvement’.

    Like us, these authors could not find any different

    features that marked out good responders.

     Implications for research

    This study recruited a group of patients who are, by

    definition, difficult to treat: they had not responded

    to other treatments and were referred to a tertiary

    pain clinic where, as a last resort, they are offered

    acupuncture. The severity of their symptoms at

    baseline (mean pain VAS score 74, mean FIQ score

    78) confirms this. Our results suggest that manual

    acupuncture could be helpful to some of these

    patients and further research is justified.

    Two problems have not been resolved: it is not

    easy to predict which patients will be able to attend

    for the whole course of acupuncture within the

    allotted time period, and it is currently impossible

    to target the treatment at the patients who are most

    likely to respond. However, we believe this research

    may be worth pursuing because acupuncture seems

    to offer a useful therapy to some patients, and is

    relatively free of side effects apart from temporary

    exacerbations of pain. There is considerable interest

    and investment in pharmaceutical research

    (pregabalin, milnacipran, duloxetine etc), even though

    medications have to be taken continuously and

    usually cause problematic side effects in this group

    of patients.

    Interestingly, the sample size for a definitive

    study may not need to be prohibitively large in similar

    populations, because there seems little variance in

    the scores for FIQ, the recommended primary

    outcome measure. The baseline standard deviation

    was much less than a quarter of the mean baselinescore in this study, and other studies in secondary

    care have similar findings.32;34 Using our data, a

    difference between groups of 8 points (10% of 

    baseline) would be identified with a total sample of 

    80 patients analysed. Martin calculated he needed a

    total sample of 50 to identify a 2 point difference in

    the FIQ scale.32

    An RCT would be feasible in the patients who

    attend this tertiary referral centre, but would have to

    be limited to only those who are likely to be able to

    attend repeatedly. Recruitment of 50 patients would

    take about two years. It seems likely that delivering

    the acupuncture treatment in primary care, close to

    the patient, might increase recruitment and attendance

    for follow-up. Modifications to our study protocol

    that we would suggest include: allowing patients

    who do not respond to drop out before the sixmonths’ follow up period, so they can try other

    treatments; and being more rigorous at ensuring that

    patients do not start other treatments at the advice

    of their GP. One patient had a course of physiotherapy

    for shoulder pain, and another took advantage of free

    aromatherapy massage. Future studies could also

    investigate the long-term outcome of offering

    continued, intermittent treatment to responders, in

    order to maintain their improvement. Finally,

    electroacupuncture should be considered for future

    studies since it was used in both positive trials

    reviewed.31;32

    Outcome measures

    This study included an excessive number of outcome

    measures (for reasons explained above). This proved

    a particular problem despite interpreters being

    available as many patients did not speak English as

    their first language. In a rigorous study, professional

    qualified interpreters are permitted but not family.

    Simple, quick outcome measures completed in clinic

    would improve future data collection.

    No measure seemed to be more sensitive to

    change than FIQ in this study, so we would

    recommend the FIQ because it is widely accepted.

    Lundeberg and Lund35 comment on sleep disorder

    in fibromyalgia and draw attention to the failure of 

    acupuncture studies to measure quality of sleep

    because pain is frequently the primary outcome

    measure. FIQ contains one question related to sleep

    so does include change of this parameter within an

    overall assessment. Understanding and completionrate for postal questionnaires were not as good as

    for questionnaires administered personally at the

    time of the appointment. The outcome measures used

    here only allowed for scoring of pain in the body as

    a whole. When treating widespread pain there may be

    – as there was in this study – improvement in pain in

    one region, which was not reflected in the results.

    For example, two patients remarked that their back 

    pain had improved considerably which made a

    difference to their mobility but this was not always

    reflected in the outcome measures.

    The number of measures needs to be reduced in

    further studies. SF-36 is long, and has no advantage

    over FIQ. Since this study was designed, a new tool

    to measure mood in pain patients has been developed

    – Depression Anxiety and Positive Outlook Scale

    (DAPOS) which would be useful in future studies.36

    Mood disorders are known to impair recovery.37 The

    one patient who maintained the improvement

    particularly well had a positive outlook. This patient

    was still in active employment, which is known to

    reduce the impact of pain related disability. For future

    studies we would recommend VAS, FIQ, and

    DAPOS.

    Conclusion

    Acupuncture may have a role as treatment for some

    patients with fibromyalgia that has been unresponsive

    to other therapies, but the response is unpredictable.

    Further research into acupuncture is indicated because

    of its lack of serious side effects. Comparisons

    between manual and electroacupuncture should be

    conducted, to determine which produces better

    results. Suggestions have been made for the design of 

    such studies, including the optimal outcome

    measures.

    Summary points

    Fibromyalgia (FM) is a common cause of chronic

    widespread pain

    The benefit of medication in FM is often limited by its side

    effects

    Acupuncture appears to offer symptomatic improvement to

    some patients with FM in a tertiary clinic

    In view of its safety, further acupuncture research is

     justified in this p opulation

    Comparisons between manual and electroacupuncture should

    Treatment protocol 

    At the first treatment, two or three of the patient’s

    most painful areas will be identified, tender points

    located, and a maximum of six (more usually four)

    fine needles (0.2mm x 15mm Seirin B type needle)

    will be inserted subcutaneously in the points that are

    the most tender and left in situ for three minutes.

    At subsequent sessions the treatment will be

    modified in light of the patient’s response: further

    schedules depend on whether the pain is worse after

    the first treatment. Treatment is to be given weeklyfor eight sessions.

    1. Schedule for patients whose pain was not 

    aggravated by the first treatment – see

     Appendix Table 1

    Those who failed to respond will receive stepwise

    increase in stimulation, involving thicker needles

    (0.3mm x 30mm Seirin B type needle) and more

    needles (maximum of 10) inserted intramuscularly.

    The needles will be left in situ for a longerperiod of time

    (to a maximum of 10 minutes) andmanually stimulated,

    ie rotated in both directions for 5 seconds every minute.

    Treatment 2: standard (0.3mm x 30mm Seirin B

    type needle) needles inserted intramuscularly, same

    number and duration as before. Treatment 3: more

    needles left in situ for the same period of time with

    manual stimulation. Treatment 4: increase the number

    of needles to the maximum, duration to 5 minutes.

    Treatment 5 to 8: increase duration to the maximum.

    In general, once the patient responds positively

    and the pain is improving, the acupuncture in that

    area will not be increased. If the patient’s pain is

    worse following any treatment session then needling

    will be reduced to the previous dose.

    In addition, points on hands for upper limb and

    neck pain (LI4) and points on the feet (LR3) for

    lower limb pain may be used. Other points that may

    be used are LI11, ST36, SP6, KI3, if they are close tothe painful area being treated or are tender.

    2. Schedule for patients whose pain is aggravated 

    by the first treatment – see Appendix Table 2

    For those patients who responded with aggravation

    of their pain, the treatment schedule will be as

    follows. Treatment 2: using the same size needle as

    in the first treatment, needle the most painful tender

    point in one painful area subcutaneously for 1 minute,

    without stimulation. If even this causes aggravation

    of the pain without any subsequent improvement

    then acupuncture is abandoned.

    If there is no change in pain following the second

    treatment, eitherthe numberof needles can be increased

    by one, or the duration increased by one minute at

    each treatment, continuing to use fine needles. Both

    parameters are not increased at the same time.
