Researchers looked at patients with chronic musculoskeletal pain who were treated with electroacupuncture and compared them to patients treated with sham electroacupuncture and to patients who didn’t receive any specific treatment (a control group). They measured opioid dose before and after treatment, pain before and after treatment, and side effects related to opioid medication. They found that:
This was a randomized controlled trial (RCT). In an RCT, patients are randomly assigned to receive the treatment under study or a comparator treatment.
Who participated in the study? This study included 108 people who had chronic musculoskeletal pain (in any part of their body) who had been taking opioid medications regularly for more than 2 months.
How was the study done?
This study had three groups:
Before they were randomized, all patients met with a pain specialist who explained the impact of chronic pain, possible problems with opioid medication, and each patient received an individual schedule for reducing their opioid medication. Patients were allowed to take non-opioid pain medications for any pain relief.

Electroacupuncture | vs | Sham electroacupuncture or usual care |
---|---|---|
Electroacupuncture is a form of acupuncture where a small electric current is passed between acupuncture needles. Electrical stimulation was done for 20 minutes. Patients had 12 sessions of electroacupuncture over 10 weeks. The electroacupuncture was provided by registered acupuncturists with at least 3 years of experience. | Sham acupuncture In sham acupuncture, needles were shallowly inserted in sham points. The needles had a flashing light and beeping sound but had no electric current. Usual care After meeting with the pain specialist and receiving their individual dose reduction schedule, these patients were offered no further treatment. After 10 weeks had passed, the patients in this group were offered electroacupuncture if they wanted it. |
Many patients with chronic pain conditions are given opioid medication to reduce their pain. The long-term benefits of opioid medications for chronic pain are not clear, and opioid medications can be associated with serious side effects. This study looked at whether electroacupuncture could assist patients in reducing their opioid medication dose, whether it could do so better than sham acupuncture or no acupuncture, and whether electroacupuncture was safe to use.
