Electroacupuncture May Help Reduce Opioid Use in Chronic Musculoskeletal Pain
Study participants were randomly assigned to receive electroacupuncture, sham electroacupuncture, or pain and medication management education for a period of 12 weeks.
Electroacupuncture may be safe and effective to reduce the use of opioid medications in patients with chronic musculoskeletal pain, according to a study published in Pain Medicine.
A total of 108 adult participants from 3 pain clinics and from the general public were recruited for this randomized blinded 3-arm trial. Criteria for participation included opioid use to treat chronic pain. All participants received pain and medication management education and were then randomly assigned to receive electroacupuncture (n=48), sham electroacupuncture (n=29), or pain and medication management education (n=31) for a period of 12 weeks. Patients in the group that had only received education were also treated with electroacupuncture at the 3-month follow up.
Opioid dosage was significantly reduced in patients who had received real and sham electroacupuncture (electroacupuncture: 20.5% reduction, P <.05; sham electroacupuncture: 13.7% reduction, P <.01; education: 4.5% reduction). Other outcomes, including pain intensity, dosage of nonopioid analgesics, and function were comparable in the 3 groups. Upon receiving electroacupuncture after the initial 12-week period, participants in the education-only group had a 47% reduction in opioid use.
“It may be necessary to identify those who tolerate and respond to [electroacupuncture] because in the current study about 50% of those who completed [electroacupuncture] had a sustained reduction in opioid medication even after termination of [electroacupuncture]. This group requires further study to identify the factors that contribute to the sustained response,” noted the study authors.
