A comprehensive review of acupuncture in pain management: Insights from current research

Abstract

Acupuncture has emerged as a significant therapeutic approach in pain management, particularly for patients suffering from chronic, acute, and neuropathic pain. Acupuncture treatments include inserting tiny needles into certain body parts to stimulate the nervous system and promote the body's natural healing processes. This review explores the historical background, mechanisms of action, and clinical evidence supporting acupuncture's efficacy in pain management. Mechanistically, acupuncture is thought to enhance the release of endorphins, modulate the nervous system, and improve blood circulation, contributing to pain relief. Clinical research suggests that acupuncture is particularly effective for conditions like osteoarthritis, back pain, fibromyalgia, and post-surgical pain. Electroacupuncture, a variation involving electrical stimulation of needles, has also shown promising results in enhancing therapeutic effects. Emerging neuroimaging studies have shed light on the brain’s response to acupuncture, supporting its role in modulating pain perception. Moreover, advancements in laser acupuncture and dry needling techniques have expanded therapeutic options. Cross-cultural acceptance and integration into national healthcare systems have also improved its accessibility. These developments reflect acupuncture’s growing role as both a complementary and alternative modality in multidisciplinary pain management protocols. Ongoing innovations continue to refine needle design, stimulation parameters, and individualized protocols to enhance treatment precision and patient outcomes. It further discusses acupuncture as a component of an all-encompassing pain treatment strategy, highlighting its integration with other modalities, such as physical therapy and pharmacological treatments. Despite its potential, challenges remain in the form of patient response variability and the placebo effect. This emphasizes the need for more rigorous clinical trials to better understand acupuncture's role and refine its applications in modern pain management practices.
