Zapping back pain: does more power mean more relief?

This small study tested whether a higher-power radiofrequency treatment works better than a lower-power one for easing chronic nerve pain that travels from the lower back into the legs. Twenty-two adults who hadn't gotten enough relief from standard treatments received one of the two treatments. Researchers tracked their pain levels, ability to function, and a blood marker for inflammation for about six weeks to see which approach was more effective and safe.
