Positional Release, also known by its parent name Strain-Counterstrain, is a natural, pain free manual technique that is an extremely effective way to relieve muscle tension and spasms (knots). The therapist uses passive positioning of muscles, bones and joints toward positions of comfort or ease. This shortens the tissues in spasm which resets proprioceptors (sensory receptors) in the tissues and establishes a more functional level of tone. The result is eased muscle pain and increased range of motion. The client need only let go and let it happen, the brain and the body do the rest.
