The presentation of compensatory movement strategies during a high load environment has been suggested as a potential risk factor for numerous lower extremity injuries. Deficiencies in ankle dorsiflexion range of motion may restrict movement pathways, potentially causing proximal compensation and, in turn, excessive stress to active and passive tissues. This article will discuss evidence surrounding the influence of a hypomobile ankle joint on lower extremity function, as well as methods to assess and improve ankle mechanics and subsequent movement patterns.
