Sway velocity was greater for the sick group in the AP axis, the vertical axis, and the
pitch axis: [M.sub.Sick] = 0.91 cm/s, [M.sub.Well] = 0.61 cm/s, F(1, 48) = 10.25, p < .05; [M.sub.Sick] = 0.31 cm/s, [M.sub.Well] 0.17 cm/s, F(1, 48) = 8.16, p < .05; and [M.sub.Sick] = 0.66[degrees]/s, [M.sub.Well] = 0.44[degrees]/s, F(1, 48) = 6.07, p < .05, respectively.
