SCIENTIFIC RESEARCH
& EVIDENCE
In addition to the extensive study conducted by Lund University in collaboration with the Swedish Hockey League (SHL) and HockeyAllsvenskan (HA), below are several other studies that demonstrates the effects of brain cooling for treating concussion. These studies point to the positive effects of cooling treatment for concussions, something that the robust study with SHL now confirms with its strong result.
EXCERPT FROM PUBLICATION
-
"In conclusion, the study demonstrated increased the vulnerability of the mildly traumatized brain to periods of elevated temperature. Elevating the brain and core temperature immediately prior to mTBI produced more severe changes in contusion volume and damage to dentate hilar neurons. This finding would suggest that strategies that include the critical measurement and management of temperatures before or following an mTBI or concussion could be beneficial in limiting tissue vulnerability and subsequent behavioral deficits."

SUMMARY
Experimental study from the University of Miami shows that mild hyperthermia in rats (39°C) gives significant more symptoms than at 37 °C. See attached full article.

SUMMARY
The scientific publication is an analysis of data from a 5-year study conducted in a collaboration between Lund University, the Swedish Hockey League (SHL) and HockeyAllsvenskan (HA). The results from the study show that treated players returned to play significantly sooner when using PolarCap® System, as well as show an immediate relief of symptoms.
Most interestingly, the study also found that long-term absence (3 weeks or more) was greatly reduced among treated players, by almost 80 percent.
