More than 80 percent of people with chronic low back pain who received a single, 10-minute pulsed radiofrequency treatment are pain-free after 1 year, a new study reveals.

The new and minimally invasive treatment was tested on 80 people who had chronic low back pain — that is, low back pain lasting for at least 3 months — due to a herniated disk.

A herniated disk, which is also referred to as a “slipped” or “ruptured” disk, occurs when the disks between the spine’s vertebrae protrude, or “herniate.” This can pinch the spinal nerves and cause pain, particularly in the lower back.

“The nerve root is a sensitive structure that when pinched becomes inflamed and causes pain,” says lead study investigator Dr. Alessandro Napoli, of the Sapienza University of Rome in Italy.

“The body reacts with muscle constriction, which decreases the distance between vertebrae, and a vicious cycle is created.”
