History of ASTR

ASTR began in 2011 when Dr. Jacob’s wife was suffering from intense TMJ/ Jaw pain for over 3 years. After the dentist gave her a mouth guard that didn’t relieve her symptoms, Dr. Jacobs took classes and researched various treatments regarding TMJ pain. He tried many of these approaches but had no success.

One morning, Dr. Jacobs’s wife woke up unable to open her jaw (lock jaw). She couldn’t open her mouth to talk or eat, so he tried some traditional medical techniques and each of these failed to resolve her condition. Finally, his wife urged him to try anything to relieve her pain. Dr. Jacobs began to experiment on her jaw with new maneuvers. To his surprise, only a few minutes later, his wife was able to open her jaw without pain.

Dr. Jacobs became motivated to adapt this concept into maneuvers and tools to treat the entire body and relieve his patients’ pain faster. ASTR has grown into a comprehensive specialty that includes a variety of ASTR tools and over 125 maneuvers.
