Association of ground reaction force load rates with the development plantar fasciitis in runners

Runners with active plantar fasciitis (PF) (n=28) demonstrated higher vertical load rates (LRs) compared to healthy controls (CON). These differences were consistent across rearfoot strikers (RFS) and forefoot strikers (FFS). Further, FFS appeared to exhibit higher lateral LRs, where RFS showed lower medial LRs, compared to CON matched for foot strike.
