Editor's note: The following letter is in response to Cliff Korn's article "Thought on Being Part of Medicince" in the October issue (www.massagetoday.com/archives/2004/10/09.html).

"Instead of cramming to know it all, let's focus on turning out stunning graduates with solid basic skills"

Dear Editor:

Mr. Korn states that he finds it "important that we do both" (relaxation and clinical massage), then proceeds to put his expectations on the entire profession by assuming that "our public shares his expectations! Quite presumptuous!

Who exactly is "our public?" I've been a successful massage therapist for 14 years, practicing relaxation massage exclusively. My public has never had any problem with this, and it has not affected my ability to build a practice wherever I've lived. I feel relaxation massage is medical massage at its finest: preventative medicine, as stress accounts for over 70 percent of visits to doctors!

Since Mr. Korn is so fond of us being a part of medicine, let me ask how many patients expect to see one doctor for "orthopedic issues, stress-related issues, sports-injury prevention, etc." Family doctors are General Practitioners and as the title implies they practice general medicine, referring patients to specialists as necessary for treatment of more specific ailments. This is how I practice my profession as well, referring my clients to bodywork specialists when I feel they would benefit from a different approach.

I simply have no interest in practicing clinical massage but I am a huge proponent of its benefits and never hesitate to refer my clients to qualified rehab therapists. Nor do I hesitate to refer clients to energy workers, Shiatsu practitioners, nutritionists, aromatherapists, body movement therapists, etc. The list is endless as massage embodies the essence of holistic health! How can we hope to be experts in all such modalities? Impossible!

The fact is that true clinical massage requires a great deal of advanced training and hands-on practice to honor the ethic "do no harm," as we must do if it truly is "all about the clients." It is impossible to include this training/practice in a 500-hour entry-level program. And there's the rub!

Must we expand entry-level programs to accomodate this neurotic need to be a "part of medicine?" Many programs are moving up to 750-1,000 hours in order to include more clinical approaches. In my opinion this is a dangerous move. A little knowledge is indeed a dangerous thing and that's exactly what we have in students graduating from such programs. They have not yet mastered basic strokes, but they are expected to understand assessment and corrective techniques that take years of study and practice to grasp. Instead of cramming to know it all, let's focus on turning out stunning graduates with solid basic skills who may choose their own courses for further study!

Editor's note: The following letters are in response to Bruce Klein's letter in the November issue (We Get Letters and E-mail, www.massagetoday.com/archives/2004/11/18.html).

"It's well known among spinal surgeons that cerebral spinal fluid does indeed pulse"

Dear Editor:

I am a massage therapist, exclusively practicing CranioSacral Therapy (CST). I also teach several courses for the Upledger Institute. Before becoming a massage therapist, however, I was a scientist. I have a PhD in theoretical physics from Rice University, and I did research in physics at the Massachusetts Institute of Technology for a number of years. I would like to address the question of why no movement of the cerebral spinal fluid (CSF) is discernable on an MRI and why serial CT scans are possible even if cranial bones move.

Leaving aside the question of whether placing the body in a very high magnetic field or bombarding it with X-rays will disrupt subtle physiological processes, how much fluid movement actually occurs and would one expect to be able to detect it if it were present? The amount of fluid movement within each cycle of the craniosacral rhythm (CSR) is very easily estimated. The average adult human has approximately 600ml of CSF in their system at any given time. That CSF is replaced on average 3 to 4 times per day. That means the brain produces about 600ml of CSF every 6 to 8 hours. The CSR has a frequency of 6 to 12 cycles per minute, or a period of 5 to 10 seconds per cycle. This corresponds to somewhere between 2,000 and 4,000 cycles of the CSR in a 6-hour period. Thus, the amount of CSF produced in a single cycle is somewhere between 0.15 and 0.3ml, much too small of a change to be detected by an MRI. There is movement of the CSF through the brain, but it is very slow. Any given cycle only moves the CSF a small amount, but cumulatively there is enough movement to replace the fluid several times per day.

Even though the fluid production in any one cycle is minute, the pressure changes that occur due to that fluid production are easily palpable. Dr. Upledger (et al.) has published several papers demonstrating rhythmic movement of cranial bones (citations for these papers are available from the Upledger Institute). He showed that cranial bones move rhythmically with average amplitude of about 0.010" or about the thickness of a piece of paper. A movement of this magnitude is easily palpable to the human hand. While I am not familiar with the resolution of a typical CT scanner, it would have to be of the order of 0.010" or less in order to detect the CSR. Even if it were able to detect it, such a small movement would cause only an imperceptible blurring of the image and would in no way prevent one from taking serial scans of a human head.

As a scientist, it does not surprise me at all that the CSR does not show up on MRIs or CT scans, nor does it surprise me that we can easily palpate the CSR - the human hand is a much more sensitive detection instrument than any imaging machine that is available today. What does surprise me is the continuing controversy over the existence of a rhythmic movement in the body that is easily palpable, even by laymen, and whose existence was clearly demonstrated by experiment many years ago.

Dear Editor:

I would like to respond to Bruce Klein's letter challenging cranial movement. First, it's well known among spinal surgeons that cerebral spinal fluid (CSF) does indeed pulse. I observed a laminectomy (removal of the back half of the vertebrae, fully exposing the spinal cord in its coverings) on one of my patients. The CSF pulse was plainly visible - indeed, the neurosurgeon pointed it out. Second, saying that the cranial bones don't move shows that Dr. Klein is not current on his anatomy. Older anatomy texts claim that the bones are fused and don't move. Not so in those of more recent vintage. Actually, only the English anatomy tradition, which we by culture follow, once claimed that the skull bones don't move. The Italian anatomists have always acknowledged that they do.

As to why CSF-flow and cranial bone movement doesn't show in MRIs and CTs: The flow and the bone movements are dramatically slow compared to blood. Other tissues move during MRI exams - the lungs, esophagus, etc. - yet they visualize perfectly well. Cranial suture movement would probably show if one was specifically looking for it and had comparable images taken the few seconds apart between maximum and minimum displacement. But the easiest way to understand cranial-bone pulsing movement is to take the time to feel it for yourself; it's not all that hard to do.
