A national study led by a local woman shows that bike-sharing programs popping up across the country appear to have an undecided side effect- head injuries. A group of researchers recently analyzed data on the treatment of head injuries at hospitals in five cities with bike share programs before and after bike share programs started and five cities without bike sharing. The results? The proportion of head injuries increased in cities after they implemented bike-sharing programs- by 14%.
So why the increase? http://www.npr.org/blogs/health/2014/06/12/321332737/brain-injuries-rose-in-cities-where-bike-sharing-rolled-out?sc=tw
