Dear Editor,                                                                                           7/1/2006

 

                        `          

This is in response to Dale G. Alexander’s article in Massage today magazine "The Phrenic Circuit" June 2006. I would prefer a warning label on all articles from smart kind gentleman such as Dr Dale Alexander. Dr. Alexander exudes a trustworthiness, which other less experienced therapists may accept as truth. The article suggests certainty when there is none and proclaims theory without telling us. My concern simply put is that although peoples thinking may very well create headache and heartache (actually shoulder and neck pain) we cannot be certain of this. The warning label would read as follows; Avoid telling clients that their adhesive Capsulitis is caused by their dark moods. Avoid assuming the role of psychotherapist without losing our role as a coach for a positive outlook. Well meaning therapists armed with Dr. Alexander’s kind assurances may want to help clients think more positively. This is got to be part of what comes naturally to most of us nurturers. Certainly all of us have reminded our clients gently and lovingly how thoughts can make them sick.  Most clients would agree.  Many clients with a little gentle prodding are on the road to health. We may want to exercise caution with clients who don’t respond to simple suggestion. There are a number of personality/thought disorders or worse that require professional psychotherapy. However we are massage therapists not psychotherapists. Know when to refer to a competent professional. This can be a slippery slope indeed. I’m quite sure Dr. Alexander would not recommend massage therapists start practicing cognitive psychotherapy with techniques like thought stopping and cognitive restructuring added while doing a soothing effleurage down the back.

 

Dr. Alexander’s theory that the phrenic nerve transmits psychological stress to constrict the sacs & tubes within the viscera is neurologically impossible. The Phrenic nerve supplies motor filaments (the part of the nerve that constricts) to only the diaphragm muscle (helps us breathe better by increasing chest cavity volume). Therefore the phrenic nerve cannot constrict the organs within the chest cavity and beyond (Heart, Lungs, Liver, Gall Bladder, Pancreas, ect.) There are extensive phrenic sensory nerve fibers (the part of the nerve that receives information but does not constrict) to some of these organs. The sensory fibers of the phrenic nerve supply structures, which are related to increased exertion e.g. the heart, large veins, membranes in the chest (Mediastinum), heart valves, abdominal membranes attached to the diaphragm, ligaments which are attached to the diaphragm, and endocrine glands, which give us the energy for exertion. The motor portion of the phrenic nerve probably forms a reflex arc (sensory nerves paired with motor nerve in spinal cord=patellar reflex=knee jerk) with the sensory nerves coming from the aforementioned structures. This gives more juice to the diaphragm (to increase O2 delivery) during intense aerobic activity. If the heart is pumping away because we are on the last 100 yards of a killer marathon this feedback loop is just what the doctor ordered. The phrenic nerves sensory fibers become excited by all of the activity of the heart, lungs, ect thus exciting the phrenic motor nerve, which increases contraction of the diaphragm to deliver that last burst of energy as we cross the finish line.

 

Another theory proposed by Dr. Alexander is that many of these “phrenic relationships are associated in most upper extremity dysfunction and pain syndromes” with the phrenic nerve transmitting psychological stress which then constricts the sacs & tubes within the viscera. As a result of the this constriction the phrenic nerve may be at least in part responsible, says Dr. Alexander, for a host of orthopedic problems; Cervical dysfunction/pain, frozen shoulder, encapsulitis, chronic rotator cuff problems, radicular symptoms (pain and numbness) into the arm, elbow, wrist, hand and fingers. Although the phrenic nerve cannot constrict sacs and tubes, as aforementioned, the sensory portion of the nerve does refer pain to a number of the structures mentioned by Dr. Alexander. For example heart disease (angina pectoris) may be felt in the chest and or down the left arm. Liver or Gall bladder problems near the diaphragm may be felt in the right shoulder. Pain in the shoulder or down the arm from irritated visceral structures does not constitute prima facie evidence for phrenic nerve transmission of psychological stress nor does it necessarily imply a role in more complex orthopedic, muscular and or skeletal problems.

 

There is no doubt a connection between our ever-busy minds and the kaleidoscope of emotions we generate and the sometimes deep-felt heartache, which really does ache in our chest. That connection is probably more nuanced and complex than Dr. Alexander surmised.
