Figure 3 Angular positions (dorsiflexion (+) and plantar flexion (−)) of the ankle joint during pre-initial phase (−30 ms-0 ms), post-initial contact (0 ms-30 ms) and reflex-induced phase (30 ms-150 ms). Solid lines represent group mean values for ankle sprain patients (black) and healthy controls (gray). Shaded areas indicate the confidence intervals (CI = 95%) of the group mean values.
