Tailored Acupuncture Lessens Pain Intensity in Chronic Pain
Nine weekly sessions of individually tailored acupuncture lessen perceived pain intensity, and improve functional capacity and quality of life, in people with the chronic pain condition, fibromyalgia, finds research published online in acupuncture.
The beneficial effects were still evident a year later, the findings show. The evidence suggests that 90 percent of people who have fibromyalgia try some form of complementary therapy, including massage, hydrotherapy and acupuncture.
But most of the data on the pros and cons of acupuncture to alleviate symptoms have been based on clinical trials of standard, rather than individually tailored, treatment.
In a bid to find out if a personalized approach would make a difference, the researchers compared individually tailored acupuncture treatment with sham treatment in 153 adults, all of whom had been diagnosed with fibromyalgia, according to diagnostic criteria set out by the American College of Rheumatology.
Both the real and simulated treatments, to which participants were randomly assigned, were provided in nine weekly sessions, each lasting 20 minutes. Participants continued to take the usual drugs they had been prescribed to alleviate symptoms (painkillers and antidepressants).
To evaluate the impact of both approaches, participants were asked about perceived levels of pain, depression, and health related quality of life (physical and mental), using validated scoring systems before treatment began, and then again 10 weeks, six months, and 12 months afterwards.
They were also asked about changes in the overall impact of their condition, as measured by the Fibromyalgia Impact Questionnaire (FIQ), for short, at 10 weeks, six and 12 months.
Analysis of the results showed that after 10 weeks, perceived pain intensity was lower among those given real acupuncture. Their pain scores had dropped by an average of 41 percent, compared with an average of 27 percent for those given the simulated treatment.
Significant differences persisted after a year, with an average fall of 20 percent in the pain score among those treated with the real thing compared with just over 6 percent for those given the simulated treatment.
FIQ scores also differed significantly between the two groups at all three time points, with reductions of 35, 25 and just over 22 percent for those given tailored acupuncture compared with 24.5, just over 11 and 5 percent, for those given simulated acupuncture.
Other aspects of pain intensity, including pressure pain threshold and the number of tender points also improved significantly more in the group given real acupuncture after 10 weeks, as did measures of fatigue, anxiety and depression.
These differences were also evident after a year, although the researchers caution that participants were using higher levels of antidepressants after a year, which may have artificially inflated the positive outcomes.
Side effects were few and mild, prompting the researchers to suggest that tailored acupuncture may be a viable treatment for fibromyalgia.
“This treatment produced an improvement in the participants’ condition, reflected by a reduction in pain intensity and enhanced functional capacity and quality of life after the intervention and during the follow up period,” they wrote.
“Such an outcome has not been reported by previous studies following the application of standardized treatments: therefore, our results suggest that applying individualized treatment algorithms when starting a course of acupuncture may be important,” the researchers concluded.
