Repeated Impacts Diminish the Impact Performance of Equestrian Helmets.

CONCLUSIONS: All riders should wear a certified helmet and replace it after sustaining a head impact. Following an impact, expanded polystyrene liners compress, and their ability to attenuate head acceleration during subsequent impacts to the same location is reduced. Replacing an impacted helmet may reduce a rider's head injury risk. PMID: 30987519 [PubMed - as supplied by publisher]
