It is obvious that the neurobiological models of subluxation are not mutually exclusive, and that any or all may be operative in a given patient.
Clinical practice requires that theoretical models of nerve dysfunction be operationalized.
This process has resulted in the development of clinical operational models. Selection of outcomes assessments is dependent upon the nature of the model employed by the practitioner. These conceptual models determine the nature of the analytical procedures employed, the type of adjustments applied, and the criteria for determining the success or failure of a given intervention. The segmental model . Subluxation is described in terms of alterations in specific intervertebral motion segments.
