In a low back pain study conducted at the U.S. Spine & Sport Foundation in San Diego, California in 2006, participants treated with Continuous Low-level Heatwrap Therapy (CLHT) prior to exercise reported less intense pain and less trouble moving after 24 hours than the control group. Study participants treated with the heatwraps also showed greater (138%) pain relief than those who received standard cold pack treatment, according to the study's research director, John Mayer, Ph.D. The study concluded that heatwraps were effective in the early treatment and prevention of Delayed Onset Muscle Soreness (DOMS)--soreness that occurs within one to two days of physical exertion.
