This systematic review examined the effects of acupuncture on hand-and-wrist pain intensity, functional status, quality of life, and incidence of adverse effects in adults.
Methods:
Searches of 6 databases and previous reviews for randomized controlled trials (RCTs) were performed. Each outcome was analyzed for participant conditions, interventions, controls, and follow-up times determined a priori. Active controls were excluded. Follow-up periods were based on Cochrane 5.1.0 guidelines. The results were tabulated and described narratively.
Results:
In the 10 included RCTs (622 participants), 6 had a low risk of bias. For cryotherapy-induced pain, 1 trial showed significant pain reduction post treatment. For rheumatoid arthritis, 1 trial shown significant pain reduction and function improvements post treatment and short-term. For carpal tunnel syndrome, 1 trial showed significant pain reduction and functional improvements intermediate-term, while 3 trials suggested no significant difference. For tenosynovitis, 1 trial showed significant pain reduction and function improvements short-term. For poststroke impairments, 1 trial showed significant function improvements post treatment and at short-term, while another trial suggested no significant difference. No significant improvements were noted for trapezio-metacarpal joint osteoarthritis. In 2 trials, adverse effects occurred in patients with carpal tunnel syndrome; yet acupuncture appeared to be relatively safe.
Conclusions:
Acupuncture may be effective and safe for short-term pain reduction and functional improvement in hand-and-wrist conditions. Clinicians should interpret the results with caution due to small sample sizes and clinical heterogeneity. Future research is warranted.
