Resumo

Background: Among non-motor symptoms of Parkinson's disease (PD), anxiety occurs in up to 67% of patients. Clinically, PD patients report worsening of tremors in anxiogenic situations. Objective: The aim of this study was to evaluate the association between motor symptoms and anxiety in PD patients and compare their performances with those of healthy volunteers. Methods: Fifteen volunteers with PD and 15 healthy volunteers without clinically significant psychiatric disorders were evaluated. Both groups were subjected to a simulated public speaking test (SPST). The following parameters were measured: visual analog mood scale (VAMS), items related to tremors of UPDRS, bradykinesia tests, blood pressure, and heart rate. Results: Results of repeated measures ANOVA indicated a significant effect on group x phase interaction (F-3.7,F-105.6 = 2.56; p = 0.046) for VAMS anxiety factor. Regarding tremors, ANOVA indicated significant differences in group x phase interaction (F-4.5,F-121 = 2.88; p = 0.021) and between the groups (F-1,F-27 d= 45.88, p < 0.001), with differences in the anticipatory phase, performance, and post-speech, compared with those in the baseline. There were no significant differences between the groups with regard to other factors of VAMS, physiological measurements, and bradykinesia. Discussion: Worsening of tremors occurred during SPST, particularly in phases with higher anxiety scores. (AU)
