Myofascial Release is a highly specialized stretching technique used by physical therapists to treat patients with a variety of soft tissue problems.
To understand what Myofascial Release is and why it works, you have to understand a little about fascia. Fascia is a thin tissue that covers all the organs of the body. This tissue covers every muscle and every fiber within each muscle. All muscle stretching, then, is actually stretching of the fascia and the muscle, the myofascial unit. When muscle fibers are injured, the fibers and the fascia which surrounds it become short and tight. This uneven stress can be transmitted through the fascia to other parts of the body, causing pain and a variety of other symptoms in areas you often wouldn’t expect. Myofascial Release treats these symptoms by releasing the uneven tightness in injured fascia.

In other words, Myofascial Release is stretching of the fascia. Small areas of muscle are stretched at a time. Sometimes the therapist uses only two fingers to stretch a small part of a muscle.

Each Myofascial Release technique contains the same components. The physical therapist finds the area of tightness. A light stretch is applied to the tight area. The physical therapist waits for the tissue to relax and then increases the stretch. The process is repeated until the area is fully relaxed. Then, the next area is stretched.
The therapist will be able to find sore spots just by feel. Often, patients are unable to pinpoint some sore spots or have grown used to them until the physical therapist finds them. The size and sensitivity of these sore spots, called Myofascial Trigger Points, will decrease with treatment.
Most patients are surprised by how gentle Myofascial Release is. Some patients fall asleep during treatment. Others later go home and take a nap. Most patients find Myofascial Release to be a very relaxing form of treatment.
