The goal of the current study was to examine whether pd patients and controls responded similarly or differently to experimentally induced increases in anxiety. For this purpose, 14 pd patients (tested during a subjective optimal on state) and 16 healthy age-matched control subjects stood in three conditions of different levels of postural threat: normal threat (quiet standing at ground level); medium threat (standing at the edge of a surface elevated to 80 cm); and high threat (same, but to cardinal cm). Outcome measures included mean position, mean power of frequency (mpf) and root mean square (rms) of centre of pressure (cop) displacements in the anterior-posterior (ap) and medial-lateral (ml) directions. age men use viagra Physiological and psychosocial measures of fear and anxiety were also recorded. viagra pills Increased threat changed postural control similarly in pd patients and controls; mpf of ap and ml cop increased and the mean cop position was shifted backward in both groups. These results indicate that during the on state, static balance in pd patients and controls is equally susceptible to the influence of anxiety. buy viagra canada Significant correlations observed between cop changes and measures of fear and anxiety provide evidence to support the proposed neural links between structures controlling emotion and postural control. Future studies should further address this issue by including more severely affected patients, by testing the influence of dopaminergic medication, by including more anxious patients, and by using dynamic measures of balance.
