- Effects of multisession prefrontal cortex tDCS or taVNS on stress, perceived stress and sleep quality : a double-blind, randomized controlled studyPublication . Reis, Laya Dalila dos; Generoso, Laura Pereira; Pereira, Gabrielly Santos; Barú, João Paulo da Silva Teixeira; Candido, Natalie Lange; Capello, Maria Gabriela Maziero; Castro, Renato Ortolani Marcondes de; Cardoso, Edvaldo José Rodrigues; Scoz, Robson Dias; Ferreira, Luciano Maia Alves; Silva, Marcelo Lourenço da; Silva, Josie Resende Torres daIntroduction: Chronic stress is a condition characterized by prolonged stimulation, leading to mental and physical weakness. It can have detrimental effects on individuals’ mental health and cognitive function, potentially causing various health issues. This article explores the potential of non-invasive neuromodulation techniques, specifically transcranial direct current stimulation (tDCS) and transcutaneous auricular vagus nerve stimulation (taVNS), in managing chronic stress and improving sleep quality.Methods: The study conducted a randomized, double-blinded, controlled trial with participants experiencing chronic stress. In total, 100 participants were randomly assigned to one of four conditions: the anodal tDCS group (n = 50), the sham tDCS group (n = 50), the taVNS group (n = 50), or the sham taVNS group (n = 50). Within each condition, participants received five sessions of either active treatment or sham treatment, with 20 min of tDCS over the dorsolateral prefrontal cortex (2 mA) for the tDCS groups, or taVNS on the left ear (20 Hz) for the taVNS groups. At baseline, post-intervention, and 4 weeks thereafter, we evaluated stress using the Lipp’s Inventory of Stress Symptoms for Adults (LSSI), perceived stress through the Perceived Stress Scale (PSS-10), and sleep quality via the Pittsburgh Sleep Quality Index (PSQI).Results: The tDCS and taVNS interventions resulted in reduced stress levels, improved sleep quality, and enhanced perception of stress.Discussion: These findings suggest that tDCS and taVNS hold promise as effective treatments for chronic stress, offering a safe and accessible approach to improving individuals’ wellbeing and overall quality of life.
- Validation of the Brazilian version of Knowledge and Attitudes of Pain questionnairePublication . Candido, Natalie Lange; Capello, Maria Gabriela Maziero; Oliveira, Guilherme Prevelato; Ferreira, Luciano Maia Alves; Generoso, Laura Pereira; Silva, Josie Resende Torres da; Silva, Marcelo Lourenço daBackground and objectives: Health professionals attitudes and beliefs about musculoskeletal pain have a negative influence on patient beliefs and outcomes. However, there is no gold standard for assessing knowledge and attitudes toward pain among these professionals. Thus, the objective of the present study was to translate, adapt and validate the Knowledge and Attitudes of Pain (KNAP) questionnaire into Brazilian Portuguese (KNAP-Br), apply the questionnaire and analyze the correlation of its results with the Neurophysiological Pain Questionnaire (NPQ). Methods: After being translated, back-translated and adapted, the NKAP-Br was applied to 60 physical therapy and medicine students for validation. The correlation between the results obtained by multiplying the scores of the questions of the NKAP-Br instrument and the NPQ was evaluated. To assess reliability, another 200 students responded to the initial KNAP-Br (T1), performed the Pain Education Program (PEP) in one week and one week after T1, the participants received access to answer the KNAP-Br end (T2). Results: Concurrent validity was assessed by the correlation between NPQ and the final KNAP-Br score. A significant correlation was found between the NPQ result (0.3 and p-value=0.0001) and the KNAP-Br score. Intragroups, 84% improved in the KNAP-Br score after studying PEP, 43.50% improved at or above the minimal detectable difference (MDD) and at or above the minimal important difference (MID). Conclusion: The questionnaire was translated and adapted respecting the Brazilian population cultural aspects and presented satisfactory reliability and construct validity, being considered valid for the assessment of knowledge and the interpretation of pain by health professionals.
