Abstract: 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.

“…Especially this latter process has been associated with freezing (Fox et al, 2001;Roelofs et al, 2010) and is thought to contribute to a vicious circle in which attention is captured by negative information, and vice versa, negative appraisals lead to a further enhancement of sensory vigilance (Mathews and MacLeod, 1994). In agreement, stronger freezing-like behavior was found in panic disorder patients (Lopes et al, 2009) and in healthy participants with a history of aversive life events (Hagenaars et al, 2012). Thus, our findings raise the question whether anxiety disorder patients may have abnormalities in the amygdala-PAG circuitry identified in the present study.…”

“…This effect was enhanced further in patients with posttraumatic stress disorder (25). Furthermore, patients suffering from panic disorder exhibit amplification of freezing-like behaviors under stressful conditions (26). Although lighting conditions were not explored in this study, it stands to reason that darkness-induced anxiety would constitute a stressful condition.…”

“…These were included in an elegant study by Azevedo et al (2005) who used a stabilometric platform to objectively assess body sway and observed freezing (reduced body sway and bradycardia) in response to mutilation but not neutral and sports pictures. Only very few other researchers have used a stabilometric platform to quantify postural freezing, but all have found associations between posture and either anxiety or threatening stimuli (Carpenter, Frank, Adkin, Paton, & Allum, 2004;Facchinetti, Imbiriba, Azevedo, Vargas, & Volchan, 2006;Lopes et al, 2009;Roelofs, Hagenaars, & Stins, 2010;Stins & Beek, 2007).…”
