Active Release Technique has been developed, refined, and patented by P. Michael Leahy, DC, CCSP. Dr. Leahy noticed that his patients' symptoms seemed to be related to changes in their soft tissue that could be felt by hand. By observing how muscles, fascia, tendons, ligaments and nerves responded to different types of work, Dr. Leahy was able to consistently resolve over 90% of his patients' problems. He now teaches and certifies health care providers all over the world to use ART. See the Active Release Technique page for more details.
