Mild chronic hyponatremia is associated with gait disturbances. Mild chronic hyponatremia is associated with gait disturbances. The recorded projection of the center of gravity over a pressure-sensitive calibrated platform or total traveled way (TTW) in three patients (A–C) after a 10-second tandem walk from right to left with eyes opened is shown. The left panel shows the TTW during mild chronic hyponatremia, and the right panel shows the TTW after correction of hyponatremia. Irregular paths of the center of pressure were observed in the hyponatremia condition (arrows). Reprinted from reference 18, with permission.
