Subluxation of the upper cervical vertebrae is regarded among chiropractors as an important cause of disease and disability. However, currently there is no animal model of the upper cervical subluxation, and so it is difficult for researchers to study the underlying mechanisms and the clinical consequences of this lesion. This research will develop a model of the upper cervical subluxation, and test whether this model compromises spinal cord function and the function of visceral organs, as many chiropractors postulate. This model will permit researchers to address important questions about the consequences and treatments of upper cervical subluxation.

  • Final Report
    We had previously reported that experiments from the earlier phases of the study were consistent with the hypothesis that relatively moderate (non-destructive) short-term compression of the upper cervical spinal cord causes a reversible impairment of spinal cord function and this is reflected in changes in cardiovascular function.  This supports, but of course in itself does not prove, the concept of the upper cervical subluxation producing effects beyond purely bio mechanical changes.

    The experiments completed to date indicate that, in an animal model, relatively moderate (non-destructive) short-term compression of the upper cervical spinal cord causes a reversible impairment of spinal cord function and this is reflected in changes in cardiovascular function. This is consistent with, but of course in itself does not prove, the concept of the upper cervical subluxation producing effects beyond purely biomechanical changes. To the extent that biological rationale is one component of clinical decision making, this may provide some guidance to clinicians confronting the case of upper cervical subluxation with, for example, cardiovascular changes. 
    Stakeholders should be encouraged to know that all experiments planned in the grant application have been completed with sufficient reliable data to produce a credible manuscript for a peer-reviewed journal. New knowledge obtained through these experiments will be used to design subsequent studies with further clinical implications.
