Applegate T. Eccentric plantarflexor torque deficits in participants with functional ankle instability

Context: Inversion ankle sprains can lead to a chronic con-dition called functional ankle instability (FAI). Limited research has been reported regarding isokinetic measures for the plantar flexors and dorsiflexors of the ankle. Objective: To examine the isokinetic eccentric torque mea-sures of the ankle musculature in participants with stable ankles and participants with functionally unstable ankles during inver-sion, eversion, plantar flexion, and dorsiflexion. Design: Case-control study. Setting: Athletic training research laboratory
