Pain-relief techniques to alleviate muscle spasms and cramping. The therapist locates and deactivates 'trigger points', which are often tender areas where muscles have been damaged or acquired a re-occurring spasm or 'kink' that worsens painfully when aggravated. The major goals are to reduce spasm inducing new blood flow into the affected area. The spasms are partly maintained by nervous system feedback (pain-spasm-pain) cycle. Spasms also physically reduce blood flow to the trigger point area (ischemia), reducing oxygen supplied to the tissues and increasing the spasm. Pressure is applied to trigger points, for a short time, which can be momentarily painful but is greatly relieving. It is common to hit the same trigger points several times during a session, but you won't be leaning into a sore spot for several minutes. Then the muscles are gently stretched to complete the relaxation process, hence the name 'spray and stretch'. Myotherapy aims to erase pain and soothe tightened muscles. People with acute or chronic muscle tension and the associated pain are likely to benefit greatly from this type of treatment.
