What about Chiropractic Research?

The Effect of Spinal Manipulation in the Treatment of Cervicogenic Headache (J Manipulative Physiol Ther 1997; 20 (5) Jun: 326–330)

RESULTS: The use of analgesics decreased by 36% in the manipulation group, but was unchanged in the soft-tissue group.The number of headache hours per day decreased by 69% in the manipulation group, compared with 37% in the soft-tissue group.Finally, headache intensity per episode decreased by 36% in the manipulation group, compared with 17% in the soft-tissue group.

Improvement After Chiropractic Care in Cervicocephalic Kinesthetic Sensibility and Subjective Pain Intensity in Patients with Nontraumatic Chronic Neck Pain (J Manipulative Physiol Ther 2006 (Feb); 29 (2): 100–106)

There was no difference between the treatment patients and the control subjects at the beginning with regard to age, sex, subjective pain intensity, range of motion, and HRA. At the 5-week follow-up, the treatment patients showed significant reductions in pain and improvement of all HRA aspects measured whereas the control subjects did not show any reduction in pain and improvement in only one HRA aspect.

CONCLUSION: The results of this study suggest that chiropractic care can be effective in influencing the complex process of proprioceptive sensibility and pain of cervical origin. Short, specific chiropractic treatment programs with proper patient information may alter the course of chronic cervical pain.

The British Study

In 1990, the British Medical Journal published a study “Low Back Pain of
Mechanical Origin: Randomized Comparison of Chiropractic and Hospital Outpatient
Treatment” by Dr. Thomas Meade, an orthopedic surgeon. He compared chiropractic
management of low back pain of 700 patients with standard hospital outpatient
treatment. Dr. Meade found “For patients with low back pain in whom manipulation
is not contraindicated, chiropractic almost certainly confers worthwhile, long
term benefits in comparison with hospital outpatient management.” He also found
that the chiropractic benefits lasted the whole three years of the study.

The Australian Study

This study showed that patients who underwent chiropractic care lost four
times fewer work days from low back pain than those treated by medical care.

Dr. Suh and the University of Colorado Project

Beginning in the 1970’s, Chung Ha Suh, Ph.D, and his colleagues
at the Biomechanics Department of the University of Colorado began a series of
studies that focused upon the functioning of the nervous system.

Among other things, they found that miniscule amounts of pressure on the
nerve roots (10mm Hg, equal to the weight of a feather falling on your hand)
resulted in a decrease in the electrical transmissions down the course of the
nerve root by up to 50%.
