Analysis of head impact exposure and brain microstructure response in a season-long application of a jugular vein compression collar

British Journal of Sports Medicine – Could a jugular vein neck collar help to reduce the possible concussive effect of head impact?

“study has generated initial evidence for a potential protective effect of the collar device”

“It supports the notion that the approach of protecting the brain internally via jugular vein compression may be a promising alternative”
