WEDNESDAY, July 5, 2017 (HealthDay News) -- Sending an electrical current directly into spinal nerves does no more than strength and mobility exercises for low back pain, a new study finds.

The procedure, called radiofrequency denervation, has become an increasingly popular way to try to ease pain arising from joints in the spine, the researchers noted.

But "our findings do not support the added value of radiofrequency denervation to a standardized exercise program," said study author Esther Maas, who conducted the investigation while at Vrije University in Amsterdam, the Netherlands.

"Based on our results, a standardized exercise program alone has to be the first choice in the treatment of these patients," Maas said.
