Counterstrain: A dysfunction due to a continuing, inappropriate strain reflex which is inhibited by applying a position of mild strain in the direction exactly opposite to that of the reflex. This is accompanies by direct positioning about the point of tenderness.

Counterstrain (Spontaneous Release Positioning) *Lawrence Jones

Counterstrain: After astute clinical observation followed by progressive expoloration, Dr. Jones made three discoveries. The three discoveries by Dr. Jones were as follows: 1. Placing the body into a position of maximum ______ can treat somatic dysfunction. 2. The _____ aspect of the patient must be evaluated, as well as the posterior, to effectively diagnose and treat somatic dysfunction. 3. No matter how successful the treatment, if the return to neutral was not done _______ the benefit of treatment was lost.

1. comfort 2. anterior and posterior 3. slowly *correlation between symptoms, Hx and PE, structural findings and associated tender points are necessary for utilization of this approach

Counterstrain: Counterstrain utilizes tenderpoints, which are most commonly found in muscle tissue. What type of technique is counterstrain?

Indirect

Counterstrain: There are 3 main theories of counterstrain mechanisms: 1. Proprioceptive theory 2. Sustained abnormal metabolism (inc. circulation; dec. inflammation) 3. Impaired ligamentomuscular reflex (strain on ligament inhibits muscle innapropriately) With proprioceptive theory, one muscle is strained while the antagonist is _______. When the antagonist is suddenly stretched, receptors of the muscle spindles are subsequently stimulated resulting in reflex contraction of ALREADY shortened muscle.

Antagonist is hypershortened * Indefinitely innapropriate * proprioceptors in short muscle act as if muscle is being stretched * Continuation of reflex = somatic dysfunction

Counterstrain: There is a relationship between the somatic dysfunction and the ID'd tenderpoints. Formation of these tenderpoints are believed to have occurred via a. myotomal, dermotomal sclerotomal b. motor points (where motor nerve crosses fascia and enters muscle to innervate)

Counterstrain: What are you looking for in the various steps of Counterstrain technique? 1. Find the most significant tenderpoint 2. Establish tenderness scale 3. Continously monitor tenderpoint 4. Place in position of comfort 5. Maintain for 90 sec 6. SLOWLY return to pre-treatment position (patient must be relaxed) 7. Retest the counterstrain tenderpoint (goal is <30)

1. Find Tenderpoint - -tenderness - -small, tense, edematous - -tenderpoint 4x more tender than adjacent tissue * **NOTE: may be 180 degrees around the body from site of presenting pain 2. Scale - 0-10 - -find 3 or below 3. Monitor 4. Position of Ease - -midline (flexion or extension) - -lateral (sidebending/rotation) * fine tune w/ small movement until reduce >70% 5. Maintain position for 90 sec - -ribs may need 120 sec - -therapeutic pulse (palpated) - -check in
