Plantar pressure distribution during gait and running in subjects with chronic ankle instability

Background Lateral ankle sprains are one of the most common injuries in athletes. Up to 32% of subjects with an ankle sprain develop residual symptoms labeled as chronic ankle instability (CAI), with a significant impact on the quality of life. In spite of many research the underlying mechanisms for CAI remain unclear. The foot roll-off pattern of subjects with CAI is one of the factors which may play an important role in recurring ankle sprains and the presence of ‘giving way’ episodes. A more lateral pressure distribution has been suggested in subject with CAI, resulting in higher risk for developing an ankle sprain, but research is limited [1]. Especially in dynamic conditions research is needed. This study includes gait as well as a running
