I was recently surprised by an exchange of online posts on a chiropractic newsgroup. A heated debate was underway concerning the issue of the asymptomatic subluxation.

One of the participants was a chiropractic radiologist who stated that he did not “believe” in the asymptomatic subluxation. His choice of terms shocked me, since the existence of subluxation is a clinical issue, not a matter of faith or belief. My first thought was to suggest that he consider joining the Flat Earth Society — group of folks who “believe” that the world is flat, despite overwhelming evidence to the contrary.

In previous columns, I have addressed neurobiological mechanisms associated with vertebral subluxation which involve processes other than nociception and pain perception. These include: nerve root compression [1]; dysafferentation [2]; autonomic changes [3]; and dysponesis [4]. Furthermore, comprehensive reviews of these and other mechanisms have been published in peer-reviewed journals [5,6].

Hause reported that compressed nerve roots can exist without causing pain and described a mechanism of progression where mechanical changes lead to circulatory changes, and where inflammatogenic agents may result in chemical radiculitis.

This may be followed by disturbed CSF flow, defective fibrinolysis and resulting cellular changes. The influence of the sympathetic system may result in synaptic sensitization of the CNS and peripheral nerves, creating a “vicious circle” resulting in radicular pain. [7]

The importance of asymptomatic lesions was reported by Wilberger and Pang who followed 108 asymptomatic patients with radiological evidence of herniated discs. They reported that within three years, 64% of these patients developed symptoms of lumbosacral radiculopathy. [8]

Whatmore and Kohi described an important neurophysiologic factor in functional disorders which they termed “dysponesis.”

Dysponesis refers to a reversible physiopathologic state consisting of errors in energy expenditure, which are capable of producing functional disorders. Dysponesis consists mainly of covert errors in action potential output from the motor and premotor areas of the cortex and the consequences of that output.

These neurophysiological reactions may result from responses to environmental events, bodily sensations, and emotions. The resulting aberrant muscle activity may be evaluated using surface electrode techniques. [9]

It is obvious that vertebral subluxation, like breast cancer and hypertension, may be asymptomatic. It is the responsibility of the chiropractor to detect and correct vertebral subluxations, based upon objective criteria, whether symptomatic or not. Those who refuse to accept the responsibility to assess subluxation do so at their peril, and the peril of their patients.

Their delusions are a public health menace.
