Effects of Acupuncture Therapy on Drug-Resistant Fibromyalgia: An Exploratory Single-Arm Nonrandomized Trial.

Fibromyalgia is a chronic condition that causes widespread pain and other debilitating symptoms. Standard medications like pregabalin and duloxetine don't work for everyone and can cause unwanted side effects. Japanese researchers investigated whether combining two types of acupuncture could help patients whose fibromyalgia hadn't responded well to medication.

The study involved seven patients with severe, treatment-resistant fibromyalgia who were taking pregabalin. Each participant received a specialized treatment combining electroacupuncture on the arms and legs with electro-scalp acupuncture (stimulation of acupuncture points on the head). Treatments were given once weekly for five weeks.

The results showed promise. Pain levels dropped significantly, decreasing from an average of 75.4 to 64.3 on a 100-point scale. Quality of life also improved substantially, with scores improving from 67.0 to 50.9 on the Fibromyalgia Impact Questionnaire. Perhaps most notably, nearly half of the participants (three out of seven) were able to reduce their medication dosage by about 10%, even while experiencing less pain. No patients needed to increase their medication during the study period.

While this was a small exploratory study without a control group, the findings suggest that combining conventional electroacupuncture with scalp acupuncture may offer relief for people whose fibromyalgia hasn't responded to standard treatments. The researchers believe this combination approach may work by activating the brain's natural pain control systems. If you're considering acupuncture for fibromyalgia, seek care from a licensed acupuncturist with experience treating chronic pain conditions.

This single-arm exploratory trial (n=7) evaluated combined electroacupuncture and electro-scalp acupuncture for drug-resistant fibromyalgia in Japanese patients receiving pregabalin. Inclusion criteria required VAS ≥50mm and JFIQ ≥50. The intervention consisted of electroacupuncture on four limbs plus electro-scalp acupuncture administered weekly for five weeks.

Primary outcomes showed statistically significant reductions in pain (VAS: 75.4±11.7mm to 64.3±17.3mm; P=0.05) and improved QOL (JFIQ: 67.0±13.4 to 50.9±18.3; P=0.02). Notably, 42.8% of patients reduced pregabalin intake by approximately 10%, representing a moderate though statistically insignificant effect. No increases in drug dosage were required. Secondary measures including anxiety, depression, catastrophic thinking, and sleep showed no significant changes.

Clinical implications suggest that combining conventional body electroacupuncture with scalp acupuncture may effectively address central sensitization and descending pain modulation dysfunction in treatment-resistant fibromyalgia, potentially reducing medication requirements while improving pain and functional outcomes.
