Our understanding of the biomechanics and neurology of the subluxation continues to evolve as more research is published which helps explain the nature of this lesion. Historically, the subluxation has been at the heart of the identity and purpose of the chiropractic profession.
Contemporary models provide new insights into this elusive and sometimes mysterious problem which we attempt to find by various clinical means and correct by the application of high-velocity, low-amplitude thrusts. Let’s review past models, but focus primarily on the latest evidence concerning the subluxation published in the recent scientific literature in order to improve our understanding, insight, and application of clinical interventions to improve patient outcomes with chiropractic care.
Older Models of Subluxation: Static Malposition and Pathology
Over the 115-year history of chiropractic, there have been many varied attempts to explain and clarify the subluxation. In the past, descriptions of this lesion were phrased in pathological terms and often included malposition, distortion of the intervertebral foramen and impingement of nerves as primary components. Henderson, et al., [1] described early notions of subluxation as static mechanical lesions, a misalignment or a bone out of place, as seen on a neutral radiograph. The authors explain that this static model has been vigorously challenged in the scientific literature.
Lantz [2] raised concerns about the strictly static, structural interpretation of vertebral subluxation and introduced his own hierarchical model including kinesiopathology, neuropathology, myopathology, connective tissue pathology, vascular abnormalities, as well as inflammatory response, histopathology, and biochemical abnormalities. Similarly, Dishman [3] described the vertebral subluxation complex in terms of various pathologies including neuropathology, myopathology, kinesiopathology, histopathology, and biochemical abnormalities.
