Complementary therapies in fibromyalgia

Alyson Huntley PhD assesses the evidence for using alternative approaches in treating fibromyalgia.

Fibromyalgia has a wide range of symptoms, of which the most commonly treated are pain and lack of sleep. Criteria developed by the American College of Rheumatology classify fibromyalgia as widespread pain in combination with tenderness at 11 or more of 18 specific sites.1

The aetiology is unclear, so treatment is symptom-based. EULAR guidelines recommend a multidisciplinary approach, including both pharmacological and non-pharmacological interventions.2

Pharmacological approaches include analgesics and low-dosage antidepressants. It is thought that learning to manage the condition is the best approach. Complementary and alternative approaches are popular with patients.

Non-pharmacological approaches include heat, hydrotherapy, rest, exercise, education and stress reduction. This overlaps with the ideology of complementary and alternatives approaches.

In a survey, 91 per cent of patients reported using alternative approaches to manage symptoms, two-thirds using multiple alternative interventions.3

Fibromyalgia produces pain at 11 or more of 18 specific sites

Acupuncture
Acupuncture is one of the most popular alternative therapies among fibromyalgia patients, and rheumatology patients in general.4 It is thought to benefit pain by enhancing endogenous descending inhibition in the CNS via a neurochemical cascade of pain-modulating endorphins, serotonin and noradrenaline, resulting in analgesia.

A recent systematic review described five small, randomised clinical trials.5 Three studies of electro-acupuncture showed positive short-term benefits, not persisting more than one month beyond intervention. In the remaining two studies, patients improved in the acupuncture group but the effects were not superior to control groups, which included at least some patients receiving an intervention.

Homoeopathy
A small randomised, double-blind, placebo-controlled crossover trial reported that a homoeopathic preparation, Rhus toxicodendron 6C, was effective for a selected subgroup of fibromyalgia patients.6

This study met with criticism and the results were reanalysed by a second party. It was concluded that the study provided no firm evidence for the efficacy of homoeopathic treatment for fibromyalgia.7

Since then, only one further randomised placebo-controlled crossover trial has been published, in which individualised homoeopathic remedies were used to treat patients with fibromyalgia. Statistically significant differences were reported in medically assessed tender point count and pain, as well as subjective criteria from the patients compared with a placebo group over three months.8

Massage
Two randomised controlled trials (RCTs) found that massage led to improvement in pain and symptoms compared with relaxation techniques or TENS, but these studies were of poor quality.

Of the two remaining RCTs, one showed no benefit from massage and the other only very short-term benefit.9

Mind-body therapies
A Cochrane review assessing multidisciplinary rehabilitation for fibromyalgia of working age adults included seven RCTs, of which more than half were of poor quality.10 The authors conclude that these studies suggest that behavioural treatment and stress management appear to be important components of pain management.

Evidence suggests cognitive behavioural therapy (CBT) and relaxation techniques are of some value, but the effect is modest and positive outcomes largely disappear over the long term.11

Although hypnotherapy has been investigated in the treatment of fibromyalgia, the studies are generally of poor quality.12 Bearing this in mind, hypnosis seems to be more effective than attention control, physical therapies and education.

Qigong, a part of traditional Chinese medicine, is based on a philosophy similar to acupuncture. There are a few small, low-quality studies looking at its benefits for fibromyalgia. The largest (n=128), most rigorous study compared a combination of qigong and mindful meditation with a control group of education over a 24-week period.

It showed that both groups improved in terms of Fibromyalgia Impact Questionnaire scores, pain and depression, but that there was no difference between them.13
