Lateral ankle sprains (LAS) and chronic ankle instability (CAI) are common musculoskeletal injuries that are a result of inversion injury during sport. The midfoot is frequently involved during inversion injury, is often overlooked during clinical examination, and maybe contributory to the development of CAI. The purpose of this study is to investigate multisegmented foot motion using a motion capture system, clinical joint physiological and accessory motion, and morphologic foot measurements in recreationally active men and women with and without a history of lateral ankle sprains and chronic ankle instability. Additionally, the effects of a joint mobilization intervention in patients with diminished multisegmented foot motion and intrinsic foot strengthening in healthy individuals will be investigated.
