BMC Musculoskelet Disord. 2013 Mar 13;14:92. doi: 10.1186/1471-2474-14-92. Harvey MP, Descarreaux M. Abstract BACKGROUND: Low back pain (LBP) is one of the most frequent musculoskeletal conditions in industrialized countries and its economic impact is important. Spinal manipulation therapy (SMT) is believed to be a valid approach in the treatment of both acute and chronic LBP. […]

Visceral responses to spinal manipulation

Authors Bolton PS, Budgell B. Journal J Electromyogr Kinesiol. 2012 Oct;22(5):777-84. doi: 10.1016/j.jelekin.2012.02.016. Epub 2012 Mar 20. Abstract 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 […]

Spinal Manipulative Therapy and Somatosensory Activation

J Electromyogr Kinesiol. 2012 Oct; 22(5): 785–794.

A relatively high velocity, low amplitude force applied to the vertebral column with […]

Changes in pain sensitivity following spinal manipulation: a systematic review and meta-analysis

The Facts: a. Spinal manipulation is a common form of treatment for musculoskeletal conditions. b. It is frequently used for the treatment of pain. c. The mechanism by which this manipulative therapy reduces pain is unclear. d. However, one method by which spinal manipulation may reduce pain is by reducing pain sensitivity. e. “Meta-analysis was […]

The basis for spinal manipulation: Chiropractic perspective of indications and theory

Henderson CN. J Electromyogr Kinesiol. 2012 Oct;22(5):632-42. doi: 10.1016/j.jelekin.2012.03.008. Epub 2012 Apr 17. Abstract 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, […]

Cerebral metabolic changes in men after chiropractic spinal manipulation for neck pain

Ogura T Altern Ther Health Med. 2011 Nov-Dec;17(6):12-7. Abstract BACKGROUND: Chiropractic spinal manipulation (CSM) is an alternative treatment for back pain. The autonomic nervous system is often involved in spinal dysfunction. Although studies on the effects of CSM have been performed, no chiropractic study has examined regional cerebral metabolism using positron emission tomography (PET). OBJECTIVE: […]

Chiropractic Science: A Contemporary Neurophysiologic Paradigm – Full Text

J Can Chiropr Assoc. 2010 Sep; 54(3): 144–146. PMCID: PMC2921779 PMID: 20808613 Dr. John Srbely, DC, PhD In order for chiropractic to reach its full potential as a healthcare profession, it must be universally integrated into the mainstream healthcare model. For this to be realized, chiropractic must first be unconditionally embraced by mainstream science. With […]

Joint mobilization reduces hyperalgesia associated with chronic muscle and joint inflammation in rats.

J Pain. 2006 Aug;7(8):602-7. Sluka KA1, Skyba DA, Radhakrishnan R, Leeper BJ, Wright A. Abstract Joint mobilization is a common treatment used by healthcare professions for management of a variety of painful conditions, including inflammatory joint and muscle pain. We hypothesized that joint mobilization would reduce the bilateral hyperalgesia induced by muscle and joint inflammation. […]

Central Neuronal Plasticity, Low Back Pain and Spinal Manipulative Therapy

JMPT June 2004 Volume 27, Issue 5, Pages 314–326 Robert W Boal, PhD Abstract Objective Recent experimental evidence demonstrating neuronal/synaptic plasticity and, in particular, long-term potentiation (LTP) and long-term depression (LTD) in spinal neurons is reviewed. The implications of these studies for possible mechanistic explanations of low back pain and its remediation by spinal manipulative […]

Pain relief produced by joint manipulation appears to involve descending inhibitory mechanisms that utilize serotonin and noradrenaline

Here is a study where they demonstrate, in the mouse model, where it was demonstrated that the pain relief produced by joint manipulation appears to involve descending inhibitory mechanisms that utilize serotonin and noradrenaline. Joint manipulation reduces hyperalgesia by activation of monoamine receptors but not opioid or GABA receptors in the spinal cord D.A. Skyba […]

Mechanism of action of spinal manipulative therapy

Joint Bone Spine Volume 70, Issue 5, September 2003, Pages 336-341 Joint Bone Spine Review Author links open overlay panelJean-YvesMaigne Abstract Spinal manipulative therapy (SMT) acts on the various components of the vertebral motion segment.
