Positional Release Therapy (PRT)

What is the positional release technique?

Positional Release Therapy (PRT) also known by its parent term, strain counter strain, is a form of manual medicine that resolves pain and tissue dysfunction. 

The primary mechanism of how positional release therapy works to alleviate somatic dysfunction and its associated pain is through manipulation of the muscle spindle. … The recoil we observe is the result of the monosynaptic stretch reflex, mediated by a stretch as well as painful stimuli.

What is positional release massage?

Clients’ Pain Release. Any massage therapist may have unknowingly practiced a variant of positional release therapy through the application of myofascial release, active release, applied kinesiology, or many other techniques that attempt to manipulate the muscle spindle to produce tissue relaxation.

Positional release therapy is an excellent adjunct to the practice of massage therapy, because it allows the massage therapist to first unwind tissue prior to manipulating it, making massage less painful and more effective, and its therapeutic effects longer-lasting.

Instead of forcefully compressing or stretching the knot or tissue, which may only engender short-acting endogenous pain relief, the tissue is unknotted and then realigned with massage therapy, further facilitating tissue perfusion and structural alignment, much like removing a kink or knot in a garden hose.

I have found positional release therapy is best applied prior to a massage, or as tender and trigger points are found during the course of a massage.

Clients will often report decreased pain, increased warmth, and tissue relaxation, as well as a sense of overall relaxation during or after the application of positional release therapy.

History of Positional Release

Positional release therapy has been evolving for more than half a century.

The history of positional release therapy is common knowledge and found in several books and other sources, including Positional Release Techniques, by Leon Chaitow, N.D., D.O.

In the early 1950s, Lawrence Jones, D.O., discovered that by placing his patients’ painful tissues in a position of comfort for a period of time, typically 90 seconds, their pain often spontaneously resolved or significantly reduced, with subsequent treatments often completely obliterating their painful condition permanently.

He initially termed his discovery positional release technique, later calling it strain-counter strain, a name based on his theory of how pain often developed and how the technique worked to resolve pain.

Jones proposed that when an individual experienced a sudden and unexpected strain, the antagonist to the strained tissue resisted, or counterstained, against the force in order to stabilize the associated joint, appendage, or body, producing discrete areas of tissue tenderness.

He also found that tender points were not often discernable to the patient unless palpated; that they were often located over tissue insertion and attachment sites; and that they required treatment before the primary area of complaint would resolve.

However, tender points were not commonly found in strained tissue, but in counterstained tissue, or the antagonist.

By simply folding counterstained tissue over itself, the tender point and the pain it produced would resolve.

Jones spent more than a decade mapping common tender point locations he observed among his patients and developed specific treatment positions, which he associated with vertebral segments and their nerve roots, based on these tender point locations. Since Jones’ foundational work, many practitioners and researchers have advanced his technique.

In 1997, in their text, Positional Release Therapy: Assessment & Treatment of Musculoskeletal Dysfunction, Kerry D’Ambrogio, P.T., and George Roth, D.C., N.D., advocated positional release therapy be utilized as a comprehensive, stand-alone therapy for the treatment of somatic dysfunction and other painful ailments.

While their treatment positions and approaches were similar to those of Jones, they provided a method by which to chart and record tender point locations. They also proposed that positioning may have to be held longer than the 90 seconds previously advocated.

Leon Chaitow, N.D., D.O. has been instrumental to the formation of strain-counter strain as a therapy, writing extensively on positional release therapy. Chaitow has provided additional guidance and emphasis on the role of touch in the application of the therapy, positing touch to be as important as positioning.

Top 10 Positional Release Therapy Techniques to Break the Chain of Pain, Part 1 and 2,” published in Athletic Therapy Today, the use of the gesticulatory, or twitch, the response of the tender point. We also did not recommend the use of the mapping schematics developed by Jones, D’Ambrogio, and Roth.

Rather, they contended that tender points could occur anywhere in the body, necessitating a thorough palpation exam.

They also proposed that specific treatment time frames were not sufficient for a full release of tissue to occur and that the articulatory response of tissue not only aided in guiding the positional release therapy practitioner in when to release the positioning, it also revealed to him the most appropriate treatment position, which I later termed the articulatory response method (patent pending).

Research On Positional Release Therapy

A multitude of research studies has investigated strain-counter strain and positional release therapy since Jones’ first publication in 1964, “Spontaneous Release by Positioning,” published in The DO.

Two such studies are “Comparing the Effectiveness of Positional Release Therapy Technique & Passive Stretching on Hamstring Muscle Through Sit to Reach Test in Normal Female Subjects,” published in 2011 in the Indian Journal of Physiotherapy & Occupational Therapy; and “Effect of Counterstrain on Stretch Reflexes, Hoffmann Reflexes, and Clinical Outcomes in Subjects with Plantar Fasciitis,” published in 2006 in the Journal of the American Osteopathic Association.

While many of Jones’ early propositions have not yet been fully examined, there now exists a greater understanding of how such a simple technique produces such profound pain relief.

Mechanism of Efficacy

The primary mechanism of how positional release therapy works to alleviate somatic dysfunction and its associated pain is through manipulation of the muscle spindle.

The source for this information is the book Neuroscience: Exploring the Brain, by Mark F. Bear, Barry W. Connors, and Michael A. Paradiso.

The muscle spindle is a proprioceptor found inside the myofibril. It is a neurological component of the intrafusal fiber and responds to two primary types of stimuli: velocity of stretch and resting length.

When stretched, the muscle spindle produces a reflexive muscle contraction of extra fuel fibers, much like a stretch rubber band. When a rubber band is stretched, it exhibits the same response to the stretch as when our knee is tapped by a reflex hammer: it bounces back.

The recoil we observe is the result of the monosynaptic stretch reflex, mediated by a stretch as well as painful stimuli.

The prevailing theory of why tender and trigger points develop and persist has been attributed to a dysfunctional muscle spindle—the spindle’s ability to correctly register velocity change and resting length has been altered, resulting in aberrant neural discharge from the spindle, which in turn produces sustained contraction.

The most comprehensive theory to date for trigger point development and persistence has been offered by Robert Gerwin, M.D.; Jan Dommerholt, P.T., M.P.S.; and Jay Shah, M.D., titled “An Expansion of Simons’ Integrated Hypothesis of Trigger Point Formation,” published in Current Pain and Headache Reports in 2004, an expansion of David Simons, M.D.’s and Janet Travell, M.D.’s (1999) integrated hypothesis of trigger point formation, outlined in their text, Travell & Simons’ Myofascial Pain and Dysfunction: The Trigger Point Manual, Volume 1: Upper Half of Body.

Gerwin and colleagues’ empirically-based theory points to a multitude of factors at play, such as unaccustomed muscle contraction, tissue acidity, increased release of calcitonin gene-related peptide, central sensitization, and hypoperfusion, rather than the muscle spindle alone as the culprit.

I have also proposed a fusimotor mechanism in the development and persistence of both trigger and tender points.

Neurochemical bonding occurs between the myosin and actin filaments as a result of either acute or chronic injury, producing inefficient hydrolysis of adenosine triphosphate, which disturbs the normal coupling and uncoupling of the filaments. I termed this the mechanical coupling theory.

Regardless of how or why tender or trigger points develop, they are problematic for the practicing clinician because they cause central sensitization; disturb normal tissue homeostasis; reduce strength and flexibility and may even cause or contribute to chronic illness and disability by impacting the immune system.

The goal of positional release therapy is to produce absolutely no pain when manipulating the tissue and muscle spindle. There is no stroking; massage; forceful, direct manipulation; or induction of pain in order to fight pain and tissue dysfunction.

Through positional release therapy, the body and its tissues are simply manipulated into a position to create an environment for the tissue to unwind itself in a nonpainful manner, making it an excellent therapy for clients who can not—or do not want to—experience pain, or who have a condition where direct, forceful manipulation of tissues would be problematic, such as with osteoporotic patients.

Increase Well-Being

Jones initially proposed that in order to master the application of this technique, it would take years and many hours of client care; however, fortunately, today there are multiple experts who offer instruction to expedite proficiency in positional release therapy, enabling the clinician to readily implement the therapy into daily practice.

Although the technique is indirect in nature and appears from the outside eye to be easy to learn and apply, instruction is vital to ensure not only expedited proficiency but also client safety, as there are some applications of positional release therapy that could cause harm if applied incorrectly.

Positional release therapy is, however, a safe and effective manual therapy for trained professionals who desire to deliver increased flexibility, strength, and enhancement of well-being, as well as effective and profound pain relief to their clients.

How does muscle energy technique work?

Muscle Energy Technique (MET) is a manual therapy that uses the gentle muscle contractions of the patient to relax and lengthen muscles and normalize joint motion.

Who invented the muscle energy technique?

Muscle Energy Technique (MET) The Muscle Energy Technique was developed by Fred Mitchell, Sr., D.O., in the 1950s as an osteopathic alternative to high-velocity manipulation. It is basically a neuromuscular mobilization system for all motion segments of the body.

How do muscles get energy?

The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.

What is PIR stretching?

The post-isometric relaxation (PIR) muscle energy technique is commonly used by osteopaths and utilizes an isometric contractual phase followed by gentle stretching of the same muscle, whereas reciprocal inhibition (RI) muscle energy technique utilizes an antagonist contractual phase followed by a gentle stretch.

PRT is based on the strain/counter strain technique. The difference is the use of a facilitating force (compression) to enhance the effect of positioning. Osteopathic mobilization technique. The technique follows the same procedure as strain/counter strain however, contact is maintained and pressure is exerted. Maintaining contact has a therapeutic effect
Passive, indirect technique. The component region of the body is placed into a neutral position, diminishing tissue and joint tension in all planes. A facilitating force, either compression or torsion, is then added to place a joint or muscle into its ease of motion. Used to treat superficial muscles, and deep intervertebral muscles to influence spinal motion direct technique. Place tissue in a neutral position to diminish tissue/joint tension in all planes. Add activating force (compression or distraction) Takes 3-4 seconds to induce a release. Good for superficial muscles or deep intervertebral muscles.
