There are several specific osteopathic techniques in wide use, many of which are named after their founders. Some of the more popular are Greenman muscle-energy, Jones counterstrain (also known as strain-counterstrain), myofascial release, and cranial-sacral therapy (formally known as osteopathy in the cranial field).
Greenman Muscle-energy Technique
Greenman muscle-energy technique involves bending a joint just up to the point where muscular resistance to movement begins (“the barrier”), and then holding it there while the patient gently resists. The pressure is maintained for a few seconds and then released. After a brief pause to allow the affected muscles to relax, the practitioner then moves the joint a little farther into the barrier, which will usually have shifted slightly toward improved mobility during the interval.
Strain-counterstrain Technique (Jones Counterstrain)
Strain-counterstrain technique (Jones counterstrain) involves finding tender points and then manipulating the joint connected to them in order to find a position where the tenderness decreases toward zero. Once this precise angle is found, it is held for 90 seconds and then released. Like muscle-energy work, strain-counterstrain progressively increases range of motion and, it is hoped, decreases muscle spasm and pain.
Myofacial Release
Myofacial release focuses on the fascial tissues that surround muscles. The practitioner first positions the painful area either at the edge of the barrier to movement or, alternatively, at the opposite extreme (the area of greatest comfort). Next, while the patient breathes slowly and easily, the practitioner palpates the fascial tissues, looking for a subtle sensation that indicates the tissues are ready to “unwind.” After receiving this indication, the practitioner then helps the tissue to follow a pattern of spontaneous movement. This process is repeated over several sessions until a full release is achieved. Myofascial release is said to be especially useful in pain conditions that have persisted for months or years.
Cranial-sacral Therapy
Cranial-sacral therapy, more properly called cranial osteopathy (or just cranial for short), is a very specialized technique based on the scientifically unconfirmed belief that the tissues surrounding the brain and spinal cord undergo a rhythmic pulsation. This “cranial rhythm” is supposed to cause subtle movements of the bones of the skull. A practitioner of cranial-sacral therapy gently manipulates these bones in time with the rhythm (as determined by the practitioner’s awareness), in order to repair “cranial lesions.” This therapy is said to be helpful for numerous conditions ranging from headaches and sinus allergies to multiple sclerosis and asthma. However, many researchers have serious doubts that the cranial rhythm even exists.
