Acupuncture for insomnia

Area of Science:

• Integrative Medicine
• Sleep Science
• Clinical Research

Background:

• Conventional insomnia treatments are effective for many, but alternative therapies like acupuncture are popular.
• The scientific evidence supporting acupuncture for insomnia remains inconclusive.

Purpose of the Study:

• To evaluate the efficacy and safety of acupuncture for treating insomnia.
• To synthesize evidence from randomized controlled trials (RCTs).

Main Methods:

• Comprehensive literature search of multiple databases up to 2006.
• Inclusion of RCTs comparing acupuncture (including variants) with placebo, sham, or no treatment.
• Data extraction and quality assessment focusing on bias, with meta-analysis where appropriate.

Main Results:

• Seven RCTs involving 590 participants were included.
• Acupuncture and acupressure showed potential improvements in sleep quality scores compared to placebo or no treatment.
• Efficacy for specific sleep parameters was inconsistent, and one study reported a mild adverse event (pain).

Conclusions:

• Current evidence from a small number of low-quality trials is insufficient to support acupuncture for insomnia.
• Larger, high-quality RCTs with robust methodology and longer follow-up are necessary to determine acupuncture's true efficacy and safety.
