Individuals with vestibular symptoms present unstable gait, imbalance and one way to measure an individual's level of imbalance is through baropodometry, widely used in clinical practice to map the area of plantar pressure through graphic records and determine displacements and oscillations. of the center of pressure through stabilometry. Furthermore, balance and anxiety are related, as they share the same central neural circuits. Thus, psychological complaints such as anxiety and depression are common in individuals with dizziness. Therefore, the present study aims to analyze the motor, functional and emotional characteristics of individuals with vestibular symptoms. The analysis of plantar pressure and center of pressure was carried out using baropodometry and stabilometry on a force platform (BaroScan®, Londrina, Paraná, Brazil) and the BaroSys software, while for functional analysis we used the TUG test and the aspect functional of the DHI questionnaire and for emotional analysis the emotional aspect of the DHI. We found that individuals with vestibular symptoms have flat feet, with higher values of maximum pressure, mean pressure, maximum pressure in the midfoot and rearfoot and mean pressure in the rearfoot when compared to people without vestibular symptoms. Furthermore, individuals with vestibular symptoms have reduced functional mobility and a greater risk of falling, in addition to having compromised emotional and mental health, with signs of anxiety and mild to moderate depressive symptoms in the majority of individuals when compared to individuals without vestibular symptoms.

Os efeitos da estimulação transcraniana por corrente contínua na dupla tarefa de indivíduos com doença de Parkinson: uma revisão sistemática
(Universidade Federal do Pará, 2022-10-31) ARAÚJO, Ana Paula Monteiro de; ALVES, Erik Artur Cortinhas; http://lattes.cnpq.br/9125390243566397; https://orcid.org/0000-0001-8824-8075
Introduction: In Parkinson's disease (PD), there are changes in brain connectivity, specifically in the motor areas and the cerebellum, when it is necessary to perform a Dual Task (DT). Added to the signs and symptoms, it causes negative repercussions on carrying out activities of daily living and the risk of falling, which is aggravated in TD conditions. On the other hand, Transcranial Direct Current Stimulation (tDCS) is capable of modulating the brain to establish new patterns of activity, acting on cognitive and motor variables, improving the functionality of these individuals. However, in the important context of TD, there is no review with this outcome in PD. Objective: To investigate whether isolated or associated tDCS is capable of altering the DT performance of people with PD. Methods: this review was based on the Core Items Guidelines for Reporting Systematic Reviews and Meta-Analyses (PRISMA) and was registered in the PROSPERO Database. The databases PubMed, Wiley, Scopus and Web of Science were used, without language or time restrictions. Clinical trials were included, which evaluated DT after tDCS (anodal or cathodal), isolated or associated when compared to the Sham or control group. Results: Only 4 studies were included. 62 participants were evaluated with Hoehn and Yahr (HY) minimum 1 and maximum 4.2 studies applied it alone (50%) and 2 studies associated it with physical exercise protocols (50%). Regarding the number of sessions, 3 authors evaluated a single session (75%) and 1 author evaluated 9 sessions (25%) associated with motor intervention. All used 2mA intensity. 3 authors used tDCS for 20 min (75%) and 1 author for 30 min (25%). 75% positioned the anode electrode in the Left Lateral Pre-Frontal Cortex (DLPFC) and the most used evaluation instrument was the Timed Up Go (75%). Conclusion: tDCS can have a positive effect on the performance of DT in PD, especially associated with pharmacological and non-pharmacological therapy. The main area stimulated was the left DLPFC, but the sample was not sufficient to define it as the best target. 20 minutes of stimulation seems to be sufficient and a greater number of sessions may provide a greater effect. Larger clinical trials with greater standardization are needed to allow better comparison between studies and reduce possible bias.
