(A) Vertical ground reaction force (dark line) with the tibial acceleration (light line) overlaid to demonstrate the similarity in timing of its peak with the vertical impact peak. (B) Vertical ground reaction force curves of a rearfoot strike (RFS) pattern and a forefoot strike (FFS) pattern. Note the distinct impact peak of the RFS pattern. (C) Tibial acceleration pattern for a RFS runner and a FFS runner. Pattern recognition can be used to distinguish footstrike pattern from these traces. Authors’ original work.
