Myofascial release (MFR) is an alternative medicine therapy that claims to treat skeletal muscle immobility and pain by relaxing contracted muscles, improving blood and lymphatic circulation, and stimulating the stretch reflex in muscles.
Fascia is a thin, tough, elastic type of connective tissue that wraps most structures within the human body, including muscle. Fascia supports and protects these structures. Osteopathic theory proposes that this soft tissue can become restricted due to psychogenic disease, overuse, trauma, infectious agents, or inactivity, often resulting in pain, muscle tension, and corresponding diminished blood flow.
The use of myofascial release as a treatment is not supported by good evidence, and using it as a replacement for conventional treatment risks causing harm.
