3. Fig 2
Amplitude of the displacement of the COP, left foot COP, and right foot COP in the ML and AP directions (mean ± SE) for (A, D) patient (n=11) group for control (n=11) group (B, E) before and (C, F) after injection of hypertonic saline. ∗Significant differences between eyes open and the other postural conditions (pairwise comparison with Student-Newman-Keuls compensation, P<.05). Abbreviations as described in table 1.
