Chiropractic Spinal Manipulation Won't Cause Chest
Injuries, Study Contends05/13/11
FRIDAY, May 13 (HealthDay News) -- Chest compressions during
chiropractic spinal manipulation result in little or no risk of
chest injury, according to new research.
The study, published in the May 13 online edition of the
Journal of Manipulative and Physiological Therapeutics, measured and examined the force of chest compressions ranging from typical to extremely rigorous and found all to be well under the threshold for injury.
"Results from this preliminary study showed that maximum chest compression during chiropractic manipulation of the thoracic spine is unlikely to result in injury," lead investigator Brian D. Stemper, associate professor in the department of neurosurgery at Medical College of Wisconsin, said in a journal news release.
"We performed this study to get a better understanding of the force limits of chiropractic manipulation. This information may lead to safer manipulation procedures and help to decrease the possibility of adverse patient outcomes," he added.
With the help of a "crash test" dummy, the researchers measured
the level of chest compression used during typical chiropractic
manipulation, as well as spinal manipulations in which
chiropractors applied maximal effort. An instrumented mechanical
device was also used to apply and measure the forces needed to
perform chest compression on the test dummy. These mechanical
forces were increased until they reached a point that would result
in injury. The study found that both typical and maximal force
manipulations by chiropractors resulted in little risk of
Despite the study's results, treatment should still be
customized for individual patients, the study authors said. Stemper
cautioned that "individual patient characteristics including age,
degeneration and gender" should be taken into account during
