Vertebral artery strains during high-speed, low amplitude cervical spinal manipulation.

Spinal manipulative therapy (SMT) has been recognized as an effective treatment modality for many back, neck and musculoskeletal problems. One of the major issues of the use of SMT is its safety, especially with regards to neck manipulation and the risk of stroke. The vast majority of these accidents involve the vertebro-basilar system, specifically the vertebral artery (VA) between C2/C1. However, the mechanics of this region of the VA during SMT are unexplored. Here, we present first ever data on the mechanics of this region during cervical SMT performed by clinicians. VA strains obtained during SMT are significantly smaller than those obtained during diagnostic and range of motion testing, and are much smaller than failure strains. We conclude from this work that cervical SMT performed by trained clinicians does not appear to place undue strain on VA, and thus does not seem to be a factor in vertebro-basilar injuries.

The  prestigious Journal of Electromyography and Kinesiology (JEK) will publish an entire issue dedicated to research on the topic of Spinal Manipulation in a Special Issue appearing in October 2012.

Published by Elsevier, the JEK is the primary source for outstanding original articles on the study of muscle contraction and human motion through combined mechanical and electrical detection techniques. As the official publication of The International Society of Electrophysiology and Kinesiology, the journal is dedicated to publishing the best work in all areas of electromyography and kinesiology, including: control of movement, muscle fatigue, muscle and nerve properties, joint biomechanics, electrical stimulation, motion analysis, sports and exercise, measures of human performance, and rehabilitation.

At the invitation of the journal Editor-in-Chief Moshe Solomonow, PhD, MD, (Hon), three prominent individuals in the forefront of spinal manipulation research were selected to serve as guest editors for the Special Issue. Chris Colloca, DC; Joel Pickar, DC, PhD; and Malik Slosberg, DC, MSc, were invited to serve as guest editors and compile related papers from the worldwide spinal manipulation field for the issue.

Forward Head Posture

The Chiro.Org Blog

Have you dropped by the Forward Head Posture Page lately?

There have been several new articles added recently.

According to Kapandji (Physiology of the Joints, Volume III), for every inch your head moves forwards, it gains 10 pounds in weight, as far as the muscles in your upper back and neck are concerned. That’s because because they have to work that much harder to keep the head (chin) from crashing onto your chest. This abnormal positioning also forces the suboccipital muscles (the ones that raise the chin) to remain in constant contraction, putting pressure on the 3 suboccipital nerves.
