Sari H. Computed Tomographic Evaluation of Lumbar Spinal Structures During Traction. Physiother Theory Pract. 2005 Jan-Mar; 21 (1):3-11
There is radiological evidence that traction of a low back disc herniation will reduce the size of the disc herniation and increase the space in the spinal canal were the spinal cord and nerve roots live which can be the cause of low back and/or leg pain.
Gudavalli R. A Randomized Clinical Trial and Subgroup Analysis to Compare Flexion-Distraction with Active Exercise for chronic Low Back Pain. Eur Spine J. 2005
Patients with chronic low back pain perceived significantly less pain regardless of what group (Flexion-Distraction vs. Active Exercise) they were in.
Patients in the Flexion-Distraction group had significantly greater relief of perceived pain according to the pain scale from 1 (no pain) to 10 (worst pain) then in active exercise by physical therapists.
Patients with chronic, moderate to severe symptoms, and pain shooting into the leg improved most with Flexion-Distraction technique versus active exercise.
Murphy DR. A Non-Surgical Approach to the management of Lumbar Stenosis: A Prospective Observational Cohort Study. BMC Musculoskeletal Disorders. 2006; 7. Feb 23 2006
Lumbar spinal stenosis patients improved by 76% and disability improved in 73%.
Patients with Lumbar Spinal Stenosis (LSS) may improve significantly with a treatment approach focusing on Distraction Manipulation.
Julita A. Spinal Manipulation Therapy Reduces Inflammatory Cytokines but not Substance P Production in Normal Subjects. JMPT. 2006 Jan; 29 (1):14-21
Chiropractic Adjustments on patients shows an overall decreased production of inflammatory cytokines (molecules that drive inflammation in the body).
In other words, adjustments can help lower inflammation in the affected body area.
Bronfort G. Efficacy of Spinal Manipulation and Mobilization for low back and neck pain: a systematic review and best evidence synthesis. Spine 4 (2004) 335-356.
a. Reviewing the literature on spinal manipulation, the data suggests that:
- Acute Low Back Pain: Moderate Evidence that spinal manipulation will provide more short-term relief than mobilization and detuned diathermy, and a small amount of evidence exists that there is a faster recovery than a commonly used physical therapy strategy.
- Chronic Low Back Pain: There is a moderate amount of evidence that suggests that manipulation has an effect similar to an efficacious prescription anti-inflammatory medication.
- Chronic Neck Pain: Moderate evidence exists that manipulation and mobilization is superior to general practitioner management for short-term pain reduction.
b. These points make spinal manipulation a viable option for care of the stated conditions.
Pickar J. Neurophysiological effects of spinal manipulation. (Review Article) Spine 2 (2002) 357-371.
Spinal manipulation impacts proprioceptive primary afferent neurons (in other words, sensory nerve input to our brain from our spine) from muscle tissue next to the spine.
Manipulation may also affect pain processing in the brain possibly by altering the increased excitability of pain perceiving nerves that happens with chronic pain.
Xue-Jun Soung. Spinal manipulation Reduces Pain and Hyperalgesia after Lumbar Intervertebral Inflammation in the Rat. JMPT, 2006;29:5-13
Activator Assisted Chiropractic Adjustments can significantly reduce severity and shorten duration of increased pain sensation caused by inflammation in the area where the nerve root exits the spinal column.
