Neural Responses to the Mechanical Characteristics of High Velocity, Low Amplitude Spinal Manipulation: Effect of Specific Contact Site

Chiro.Org Blog: This animal study showed that contact site for an HVLA-SM can have a significant effect on the magnitude of sensory input arising from muscle spindles in the back. […]

Altered Central Integration of Dual Somatosensory InputAfter Cervical Spine Manipulation

Chiro.Org Blog: This study suggests that cervical spine manipulation may alter cortical integration of dual somatosensory input. These findings may help to elucidate the mechanisms responsible for the effective relief of pain and restoration of functional ability documented after spinal manipulation treatment. […]

Spinal Manipulative Therapy and Somatosensory Activation

Chiro.Org Blog: The goal of this article is to briefly update our knowledge regarding several physical characteristics of an applied SMT, and review what is known about the signaling characteristics of sensory neurons innervating the vertebral column in response to spinal manipulation. Based upon the experimental literature, we propose that SMT may produce a sustained change in the synaptic efficacy of central neurons by evoking a high frequency, bursting discharge from several types of dynamically-sensitive, mechanosensitive paraspinal primary afferent neurons. […]

Specific Potentialities of the Subluxation Complex

Chiro.Org Blog: This chapter describes the primary neurologic implications of subluxation syndromes, either as a primary factor or secondary to trauma or pathology, within the cervical spine, thoracic spine, lumbar spine, and pelvic articulations. […]

The Subluxation – Historical Perspectives Part II

Chiro.Org Blog: This paper reviews some of the early uses of subluxation and manipulation identifying highlights, to help the reader appreciate that subluxation and manipulation, both spinal and general, are as old as civilisation itself. […]

The Subluxation – Historical Perspectives

Chiro.Org Blog: This paper describes the controversy surrounding terminology arrived at through consensus in the latter part of the 20th century in addition to ongoing issues surrounding the use of the term subluxation. […]

The Subluxation Complex Saves Diagnosis for Texas Chiropractors

Chiro.Org Blog: The Texas Medical Association (TMA) and the the Texas Medical Board (TMB) takes one in the shorts, as the Texas Court of Appeals denies their attempt to halt chiropractors from diagnosing patients. […]

The Basis for Spinal Manipulation:Chiropractic Perspective of Indications and Theory

Chiro.Org Blog: It is reasonable to think that patients responding to spinal manipulation (SM), a mechanically based therapy, would have mechanical derangement of the spine as a critical causal component in the mechanism of their condition. Consequently, SM practitioners routinely assess intervertebral motion, and treat patients on the basis of those assessments. In chiropractic practice, the vertebral subluxation has been the historical raison d’etre for SM. Vertebral subluxation is a biomechanical spine derangement thought to produce clinically significant effects by disturbing neurological function. […]

Visceral Responses to Spinal Manipulation

Chiro.Org Blog: While spinal manipulation is widely seen as a reasonable treatment option for biomechanical disorders of the spine, such as neck pain and low back pain, the use of spinal manipulation to treat non-musculoskeletal complaints remains controversial. This controversy is due in part to the perception that there is no robust neurobiological rationale to justify using a biomechanical treatment of the spine to address a disorder of visceral function. […]

Posttraumatic Subluxation-Fixation Implications: Etiology, Effects, and Common Coincidental Factors

Chiro.Org Blog: The kinetic aspects of spinal biomechanics are an important consideration in traumatology since the totality of function is essentially the sum of its individual components. However, although reminders are frequently given, the multitude of causes and effects of an articular subluxation complex (spinal or extraspinal) will not be detailed here that is primarily directed to chiropractic clinicians and advanced students who are well acquainted with standard hypotheses. For a detailed description, the reader is referred to Schafer RC: Basic Principles of Chiropractic: The Neuroscience Foundation of Clinical Practice. […]

Radiologic Manifestations of Spinal Subluxations

Chiro.Org Blog: This chapter describes the radiologic signs that may be expected when spinal subluxations are demonstrable by radiography. Through the years, there have been several concepts within the chiropractic profession about what actually constitutes a subluxation. Each has had its rationale (anatomical, neurologic, or kinematic), and each has had certain validity contributing to our understanding of this complex phenomenon. […]

Cerebral Perfusion in Patients with Chronic Neck and Upper Back Pain: Preliminary Observations

Chiro.Org Blog: In this group of patients with neck and/or upper back pain, NDI scores strongly predicted cerebral hypoperfusion. Spinal joint dysfunction may be involved via hyperactivity in the regional sympathetic nervous system. […]

Dump Subluxation?   Give Me a Break!

Chiro.Org Blog: What causes subluxation? Exactly how does it cause nerve interference? What kinds of adjustments work the best, and why? How do adjustments work, anyway? Does any of that really matter in practice? What should our science address, and how should we do it with such limited resources? Why are there so many chiropractic techniques out there, each with its own method of measuring a subluxation? The discussion at the conference was simply more formal, more academic and more public, as it should be. Professional progress demands answers to these questions. […]
