Multiple acupuncture therapies, particularly acupoints catgut embedding, auricular acupressure + manual acupuncture, and electroacupuncture + acupoint application, significantly improve insomnia symptoms.
In this research, a systematic literature search was conducted to extract data from 57 randomized controlled trials involving 4678 patients who underwent various acupuncture therapies for primary insomnia. The researchers independently screened the literature and performed a risk of bias assessment. Data from the trials were analyzed using R and Stata software, followed by an evidence assessment using the Grading of Recommendations Assessment, Development, and Evaluation system.
Results showed that various acupuncture therapies, particularly acupoints catgut embedding, auricular acupressure or auricular acupuncture plus manual acupuncture, and electroacupuncture plus acupoint application, showed better effectiveness in improving insomnia, compared to the usual treatments. However, differences between the therapies were considered small or insignificant. The most common minor adverse events reported were hematoma, pain, headache, and bleeding.
