Does this sound like you? If so, you will definitely be interested in these latest research findings in a study published by the Experimental Brain Research journal.

This study was enabled through a partnership between Spinal Research, the New Zealand College of Chiropractic and the Hamblin Trust.

In the fully randomised research process, a control group of participants were set up but not adjusted. This group was asked to perform maximum contractions using leg muscles and was seen to fatigue over the course of the study.

The researchers contrasted this with the group that did receive chiropractic adjustments and saw a major shift in the way the brain drove the muscle. “There was a change in the H-reflex happening at the spinal cord level. Our results were showing that change (in the H-reflex) isn’t a spinal cord phenomenon. The brain was changing that reflex effect. Our subjects got stronger (in comparison to the control group)” observed Haavik and her fellow researchers.

The study showed:

· an increase of almost 60% in the electrical activity readings from specifically targeted muscles

· a 16% increase in absolute force measures

· a 45% increase in the drive from their brain to their muscle

· a small but significant shift in the H reflex curve, which is a neurophysiological measure of spinal cord excitability.

“What we can say based on this study is that when we adjust subluxations, we improve strength, we prevent fatigue and we change the way the brain drives our muscles. That’s pretty cool” said Heidi Haavik.

However according to Haavik, this is just the beginning of what can be discovered and proven through research. “We know that adjustments cause improvements, but how long does this last for? What about after an hour? What about after a week? What happens after three weeks of chiropractic care? What happens after a month? If there was more funding available, we could get so much more done.”

“When we adjust dysfunctional segments or subluxations, we change the way the brain processes what’s going on in our bodies. Hence we are able to better processall that sensory information from through-out the body, and control the body in a better way,” says Haavik.
