Fig. 4From: The effectiveness and sustainability of supervised balance training in chronic ankle instability with grade III ligament injury: a one-year prospective studyMeasurements of isokinetic contraction muscle strength. Dotted line indicates the declining muscle strength after the balance training. PF, plantarflexion; DF, dorsiflexion; EV, eversion; IV, inversion. * indicated p < 0.05 for comparisons within the pre-training and each time point of post-trainingBack to article page
