Post-Isometric Relaxation Stretching

What is PIR?

Post-Isometric Relaxation Stretching aka (PIR) is a stretching technique where the doctor passively moves the involved muscle to the patient's end range of motion.  After this point the patient resists against the stretch with approximately 10-20% of their maximal strength for about 10 -15 seconds. This is followed by the patient relaxing in which the muscle will release and move to its new end range of motion.  This succession will repeat a few times until the desired end range of motion is reached which in return can decrease muscle spasm and  joint restrictions.
