Abstract

The aim of this prospective study was to compare ankle kinematics between runners with and without plantar fasciitis (PF). We biomechanically analysed 719 runners (17 PF and 702 non-PF) using a 3-D motion capture system during overground running at their self-preferred speed. An independent t-test was performed to assess ankle kinematics during the stance phase of running (at initial contact, at maximum and range of motion). Runners with PF displayed abduction ankle angle approximately 3^o lower than the non-injured runners at maximal adduction (P = 0.006; d = 0.68). In conclusion, it appears that a higher ankle abduction (external rotation of the foot) may be a protective factor for PF. This information appears to be valuable for assessing running technique and may be beneficial to clinicians, coaches and runners who are afflicted with PF.
