The results of a recently published study from the November/December Cervical Spine2001 issue of the Journal of Manipulative and Physiological Therapeutics revealed that cervical range of motion was significantly improved with chiropractic adjustments. The study conducted was a double-blind randomized controlled trial performed at the outpatient clinic at Phillip Chiropractic Research Centre, RMIT University, in Melbourne, Australia.
The initial study involved 105 individuals who were randomly separated into two groups. One group was administered chiropractic adjustments while the other group received a "sham", or fake adjustment. Range of motion testing was then performed periodically over the course of the 12 week study. Active range of motion was measured by using a strap-on head goniometer consisting of an inclinometer dial for measuring lateral flexion and a compass dial for measuring rotation. These motions were chosen because gravity would play less of a role and therefore the results would be more accurate.
According to the researchers, the group that received actual adjustments experienced, "active range of motion in the cervical spine increased significantly." Their conclusion was, "Spinal manipulation of the cervical spine increases active range of motion."
As obvious as this may seem, the results are profound for such a large portion of the population. Not only does restricted range of motion play a large part in many health problems, but another growing concern is the lack of mobility in the elderly population.
