Acupuncture and Fibromyalgia
Fibromyalgia is estimated to affect two per cent of the population. It
is a chronic condition causing pain, stiffness and tenderness
of the muscles, tendons, and joints. Fibromyalgia is also associated
with sleep disturbances, fatigue, anxiety, depression and disturbances
in bowel function.
With the development of improved imaging techniques, fibromyalgia is
thought to be due to an over-sensitivity of the brain and spinal cord
(central nervous system ‘CNS’), leading to chemical imbalances within.
The exact cause of this is not fully understood, however links have
been associated with infection, stress and genetic predisposition. The
brain and spinal cord are constantly
carrying excitory and inhibitory signals regulating sensory (touch)
information from the outside world. When this becomes out of balance
the perception of pain can become distorted. In fibromyalgia sufferers,
imaging techniques have illustrated over-activity in brain areas
correlating to pain perception. Also, higher levels of excitory
neurotransmitters glutamate and substance P have been found in the
spinal fluid.
Acupuncture is theorised to have a dampening effect on these brain
areas relating to pain and through inducing inhibitory
neurotransmitters in the spinal canal by the stimulation of pain fibres
at the acupuncture points. Current treatment includes cognitive therapy
to help identify emotions that contribute to excitation in brain areas
dealing with pain, and medication
to help regulate neurotransmitters within the CNS.
Although more research is needed there are numerous studies
investigating how acupuncture may help in the treatment of
fibromyalgia. A random controlled trial by Martin et al (2006) from the
Mayo clinic found that acupuncture significantly improved symptoms of
fibromyalgia. Symptomatic improvement was not restricted to pain relief
and was most significant for fatigue
and anxiety. This study was based on six sessions of acupuncture.
