The Ancient Remedy for Modern Ailments: Analysis of Manual, Laser, and Electro-Acupuncture Therapy Usage on Carpal Tunnel Syndrome

In the United States, while acupuncture is still primarily used as a complementary therapy, consumer interest and usage are steadily increasing. Carpal tunnel syndrome (CTS), a condition where the median nerve is compressed in the wrist, can lead to numbness, tingling, weakness in fingers, and thus impaired hand function, possessing significant burdens to patients suffering from this chronic disease. Multiple acupuncture applications exist such as electroacupuncture, auricular acupuncture, laser acupuncture, moxibustion, and acupressure; very few comprehensive studies have been done in comparing their effectiveness in treating CTS. In this study, we aim to conduct a literature review with the primary objectives as follows: To elucidate the underlying mechanisms by which acupuncture exerts its therapeutic effects on carpal tunnel syndrome (CTS). To systematically evaluate the comparative efficacy of various acupuncture modalities in the management of CTS. While acupuncture appears to be a promising treatment option for CTS, compared to electroacupuncture, laser acupuncture demonstrated superior outcomes in reducing symptom severity and improving functional status in patients with nonsevere CTS. Acupuncture was more effective than night splints in reducing pain but did not outperform medication in improving symptom severity or electrophysiological parameters. Acupuncture, when combined with physiotherapy, showed benefits in reducing pain, disability, and improving grip strength compared to physiotherapy alone.
