Abstract

BACKGROUND: Anticipatory anxiety can be described as a conditioned response with a defensive posture of freezing and autonomic activation. The purpose of this study was to assess the postural control analysis and autonomic activation in panic disorder (PD) patients presented with visual stimuli. METHODS: PD patients (n=29) and healthy controls (n=27) stood on a force platform while viewing a series of anxiogenic, mutilation, and neutral pictures. Skin conductance responses and the displacements of the center of pressure were measured. RESULTS: Overall, the PD patients demonstrated significantly reduced body sway, increased mean power frequency, and increased skin conductance compared to control group throughout the experiment (P<.05). PD patients also showed a negative correlation between anticipatory anxiety and mean sway area throughout the experiment. However, there was no significant difference in body sway velocity compared to healthy controls while viewing the anxiogenic block of pictures or the neutral block. CONCLUSIONS: Our data shows that PD patients experiencing anticipatory anxiety may present with lower mobility, consistent with the freezing behavior of the defense cascade. The data also shows that PD patients do not have a postural instability when confronted with specific anxiogenic context. The importance of this study is that it objectively demonstrates freezing-like behavior in PD patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
