About eight or nine years ago there was a proliferation of back row volleyball players wearing helmets after a concussion. That lasted about two years. Then studies started showing helmets didn't help prevent concussions and may even have increased the chances of subsequent concussions. I haven't seen a volleyball player wear a helmet in many years. You would think with all the technology there would be some device that could be worn to greatly reduce concussions. So far it hasn't happened.
