Post Isometric Relaxation is ideal for treating postural muscles or muscles responsible for: walking, sitting, and standing. As these muscles are responsible for maintaining the body’s posture against the gravity, it tends to shorten. Thus, we can experience muscle tightening and spasms. Among these postural muscles are the: upper trapezius, latissimus dorsi (lats), muscles found from the cranial base up to our collarbone, broad muscles on our mid-back, pectoralis major and minor, chest muscles, etc. You will observe that most of these muscles belong to the upper body.
PIR is also ideal for treating muscles in the lower body such as the hamstrings, rectus femoris, quadriceps, and thigh muscles.
One crucial point that you must consider is when the muscle gets overstretched. A muscle is being overstretched once you feel the pain while the therapist is lengthening it or applying this technique. It means that instead of getting relaxed after the release, you will feel the pain. However, there are instances that you may feel slight soreness, but it will be gone after a few days.
