Fig. 2From: The effectiveness and sustainability of supervised balance training in chronic ankle instability with grade III ligament injury: a one-year prospective studyMeasurements during the walking (a, b) and the single limb standing (c, d). TTBML (AP)m: mean value of the minimum time to boundary in the medial-lateral (anterior-posterior) direction, TTBML (AP)a: absolute minimum time to boundary in the medial-lateral (anterior-posterior) direction. HM, Medial heel; M2, the 2nd metatarsal heads. Dotted line indicates the declining variables after the balance training. * indicated p < 0.05 for comparisons within the pre-training and each time point of post-trainingBack to article page
