Active Isolated Stretching (AIS)


Developed by Aaron Mattes, Active Isolated Stretching (AIS) is a type of stretching that lengthens muscles and provides superficial and deep fascial release, restoring both flexibility and range of motion to muscles and joints.

Active means the client participates in the stretch, actively assisting with the movement. The body is positioned in specific planes to isolate a muscle or muscle group which is then stretched to lengthen the muscle and fascia.

There are 3 main components to AIS:  1) breathing to aid in relaxation during the stretch;  2) active movement by the client;  and 3) duration of 2 seconds per stretch.
