In three randomized trials, treatment of chronic low back pain with radiofrequency denervation, a procedure that can be performed with different techniques including the application of an electric current to the pain-conducting nerve, resulted in either no improvement or no clinically important improvement in chronic low back pain, according to a study published by JAMA.
Low back pain causes more disability than any other condition and has major social and economic consequences. Even though radiofrequency denervation is a commonly used treatment, high-quality evidence for its effectiveness is lacking. Esther T. Maas, Ph.D., of Vrije Universiteit Amsterdam, the Netherlands, and colleagues report the results of three randomized clinical trials that were conducted in 16 pain clinics in the Netherlands.
