Muscle Energy Technique is one of the most effective and valuable manual techniques for the identification and correction of somatic asymmetry and hypomobility aka joints out of alignment and reduced range of motion. These techniques can be used to find and correct the causes of all types of pain. They are pain free and highly effective techniques that attain resolution of the problem with dramatic results.
Unlike manipulative techniques, MET works via evidenced-based neuro-physiology using the muscle spindles to release tight muscles and decrease tone and excitability, thus restoring the bones and joints to normal mobility and returning them to symmetrical and smooth function.

Why manipulations should be avoided and MET used instead:
