Active Isolated Stretching Course

Active Isolated Stretching Course for Massage Therapists and Fitness Professionals

Active Isolated Stretching is a cutting-edge and innovative form of stretching that works. AIS was developed by Kinesiologist Aaron L Mattes that utilizes the inherent properties of muscles and soft tissue in order to not only effectively isolate and lengthen a target muscle, but also to enhance the connection to the central nervous system. The result, in addition to remarkably increased flexibility, is better control and quicker firing of the muscles. This work will prove to be an invaluable tool in both the treatment and prevention of musculoskeletal conditions as well as degenerative neurological conditions. Because of the interaction with the central nervous system, this work has stunning results with degenerative neurological conditions that can otherwise not be effectively treated through manual therapy. Broaden your scope of practice by learning one of the most cutting edge techniques in the bodywork world!

Students will learn to:

  • Assess the ROM of each joint compared to their Normal ROM

Thomas J. DuBois

Thomas J. Dubois was drawn to the field of massage as an exchange student in college in Nagpur, India.  During his time in India, Thomas learned to speak, read, and write Hindi, and was intrigued by the health benefits of regular massage, something that has been practiced routinely in India to treat a wide variety of health conditions for thousands of years. This experience led him to pursue massage therapy education.

After graduating from the Hudson Valley School of Massage Therapy in West Park, New York, Thomas specialized in orthopedic massage and the Active Isolated Stretching and Strengthening technique. In 2012 Thomas received permission from the founder of the AIS technique, Aaron L. Mattes, to teach it to other massage professionals as a continuing education course.

Thomas has a practice in Glenwood Springs Colorado he works with injuries, chronic pain and helping athletes improve physical performance. He also teaches Kinesiology and bodywork at the Costa Rica School of Massage Therapy.

What’s Not Included


  • AIS gives us a way to treat parts of muscles that cannot be accessed with manual pressure.
  • Because your clients are active in the motion it is less work for the therapist and easier on the therapist’s body than traditional massage.
  • Think about how effective you can be if you know how to precisely stretch each muscle that you also treat with massage
  • Clients remain fully clothed while receiving AIS therapy so this can be a good and thorough and effective approach to clients who do not like to disrobe for massage.
  • Adding a new service to your list of treatments broadens your market.
  • AIS therapists work with injuries, chronic pain and athletic performance. Because AIS also works with the way the nervous system communicates with the target muscle AIS can be very helpful in managing some symptoms of neurological conditions such as parkinsons, multiple sclerosis, cerebral palsy and others
  • Learning new techniques in an area abundant with the healing qualities of nature, fresh food and sunshine is an experience unto itself.
  • Being able to stay on site or close by and give all of your focus to the technique you are learning will have you ready to use these techniques on the first clients you see after the course!
