Injuries, stress, inflammation, trauma, and poor posture can cause restriction to fascia. Since fascia is an interconnected web, the restriction or tightness to fascia at a place, with time can spread to other places in the body like a pull in a sweater. The goal of myofascial release is to release fascia restriction and restore its tissue health.
In medical literature, the term myofascial was used by Janet G. Travell M.D. in the 1940s referring to musculoskeletal pain syndromes and trigger points. In 1976 Dr. Travell began using the term "Myofascial Trigger Point" and in 1983 published the famous reference "Myofascial Pain & Dysfunction: The Trigger Point Manual". Some practitioners use the term "Myofascial Therapy" or "Myofascial Trigger Point Therapy" referring to the treatment of trigger points, this is usually in medical-clinical sense.
Here the term Myofascial Release refers to soft tissue manipulation techniques. It has been loosely used for different manual therapy, soft tissue manipulation work (connective tissue massage, soft tissue mobilisation, Rolfing, strain-counterstrain etc). There are two main schools of myofascial release: the direct and indirect method.
