Concussion study: UBC’s Thunderbirds use their heads to advance science

Canadian Chiropractic Research Foundation funds concussion study at the University of British Columbia.

UBC football players are helping advance the science around concussions — using their own heads.

When the Thunderbirds take to the field for the national semi-finals today a number of them will be wearing head sensors that take measurements to help researchers unravel the impact of concussions on athletes.

“What we’re trying to do is get a little more info on what’s occurring in head trauma and football,” said Harrison Brown, a PhD candidate at UBC in Kinesiology.

The study is also uncovering patterns or trends, such as,  “the differences between positions, practices and games, for example,” Brown said.

More than a dozen players, including the starting quarterback and starting running back, volunteered for the study, funded by the Canadian Chiropractic Research Foundation.

Brown said sensors called “xPatches” — an impact sensing patch — are put behind the players’ ears and worn during practices and games.

Researchers study the number, and the intensity, of hits players take, as well as the effects.

So, while the UBC Thunderbirds take on St. Francis Xavier’s X-men in the hopes of advancing to the Vanier Cup, they will advance science no matter what the final score of the game.

The results of the 2-year study are expected next spring.

OBJECTIVE:   The aims of this study were to investigate the response of the autonomic nervous system based upon the area of the spine adjusted and to determine if a cervical adjustment elicits a parasympathetic response and if a thoracic adjustment elicits a sympathetic response.

METHODS:   Forty patients (25-55 years old) met inclusion criteria that consisted of normal blood pressure, no history of heart disease, and being asymptomatic. Patients were evaluated pre- and post-chiropractic adjustment for the following autonomic responses: blood pressure and pulse rate. Seven patients were measured for heart rate variability. The subjects received either a diversified cervical segment adjustment or a diversified thoracic segment adjustment.

RESULTS:   Diastolic pressure (indicating a sympathetic response) dropped significantly postadjustment among those receiving cervical adjustments, accompanied by a moderate clinical effect (0.50). Pulse pressure increased significantly among those receiving cervical adjustments, accompanied by a large effect size (0.82). Although the decrease in pulse pressure for those receiving thoracic adjustments was not statistically significant, the decrease was accompanied by a moderate effect size (0.66).
