Also, because a diffuse and complex neural network regulates the SCR, it may prove difficult to correlate fear-related behaviors in PTSD to specific brain centers when using this measure.
We constructed a conceptual model to explain why clozapine did not preserve normal freezing behavior, even though neural correlates of fear conditioning indicated a positive outcome.
Furthermore, most studies focused only on socio-demographics and/or health-related variables and hardly incorporated an extensive range of potential correlates of fear of falling including psychosocial variables.
While there have been previous studies (see above), most studies focused only on socio-demographics and/or health-related variables and hardly any study incorporated an extensive range of potential correlates of fear of falling including psychosocial variables, which would enable the independent contribution of specific variables to be determined.
Although we identified four socio-demographic, five health-related and five psychosocial factors significant univariate correlates of fear of falling, the independent correlation of only female sex, limitations in activity of daily living and falls history remained when covariates were taken into account.
Secondary aims focused on whether cognition performance is correlated to fear of falling, walking velocity, and a patient-rated measure of walking ability.
Reduced warm glow did not correlate with fear of criticism (ρ = −0.14, p = 0.290) but showed a trend to be associated with fear of intimacy (ρ = −0.26, p = 0.035).

Diastolic blood pressure and heart rate variation correlated with fear and discomfort.
