<qa>  What is the most common problem in weight bearing ankle dorsiflexion?Increased musculoarticular stiffness MAS of the talocrural joint is a frequently encountered problem, identified during evaluation of weight bearing ankle dorsiflexion WBADF. Such stiffness may follow ankle injury such as ankle sprain. In such a situation, MAS could be increased and might leads to a lack of joint flexibility as well as decreased dorsiflexion range-of-motion ROM, however asymmetric rigidity does not necessarily always follow ankle sprain. Nevertheless, MAS is an important and necessary component of normal stability of the talocrural joint and could help to prevent abnormal ankle joint movement and ankle sprains.
