- Ambientes assistidos por tecnologia mainstream para a promoção de independência em pessoas com deficiênciaPublication . Tavares, Rafael Gaspar dos Santos; Sousa, Helena; Ribeiro, JaimeA utilização de dispositivos inteligentes num determinado ambiente altera as suas caraterísticas através da criação de ações facilitadoras de desempenho. O controlo destes dispositivos é centralizado no smartphone e podem ser associados interfaces como os smart speakers (SS), para controlo por outros meios, como a voz. Nosentido de explorar a sua aplicabilidade na deficiência neuromotora, foram produzidos dois estudos. O primeiro estudo faz um levantamento do estudo da arte, mapeando o conhecimento existente com uma metodologia de revisão de escopo. Para o estudo subsequente foi desenhado um estudo de caso exploratório e descritivo de abordagem mista, em que se procurou identificar e descrever possíveis varações no desempenho de uma pessoa com Diagnóstico de Distrofia Muscular de Duchenne e sues cuidadores, decorrentes da integração de dispositivos loT controlados por SS no ambiente domiciliar. As metodologias aplicadas permitiram caracterizar a aplicabilidade dispositivos loT controlados por SS em pessoas com deficiência. Os SS demonstram real potencial para atuar como ECU em desenvolvimento de ambientes assistidos na deficiência.
- The effects of a mindfulness-based program on higher education studentsPublication . Serrão, Carla; Rodrigues, Ana Rita; Ferreira, TiagoBackground: Entering higher education is a process with multiple challenges that requires the mobilization of personal, social and instrumental resources. As a result, students tend to experience grater stress, anxiety, and depression. In this regard, mindfulness-based interventions (MBIs) can serve as a useful tool to help students deal with these demands. Objective: This study aimed to evaluate the effect of a Mindfulness in Education program in reducing stress, anxiety, and depression symptoms among students. Methods: Forty-four students of higher education from four degrees in the fields of Social and Cultural Sciences participated and finished surveys before and after the 12-weeks intervention, measuring stress, depression, anxiety, mindfulness, and self-compassion. Twenty-three students (82.61% female; Mage = 20.35 DPage = 3.24) participated in Mindfulness in Education. These participants were paired with 21 students (90.48% female; Mage = 18.67, DPage = 0.73), which constituted the control condition. Results: The results showed a session × condition interaction that was statistically significant for depression (p < 0.012) and stress (p < 0.026). In the follow-up exploration, the experimental condition revealed a statistically significant and moderate change in the severity of the symptoms of depression [t(14) = –2.315, p = 0.036, ξ = 0.304, 95% CI (–0.023, –0.499)] but not at the stress level [t(14) = –1.443, p = 0.171, ξ = 0.223, 95% CI (–0.006, –0.364)]. Conclusion: Outcomes were promising, adding to evidence that MBIs can play an important role in helping students manage stress and depression. However, it is still necessary to investigate the mechanisms underlying this type of interventions.
- Effects of bihemispheric motor cortex transcranial direct current stimulation (tDCS) on dual-task motor performance in chronic stroke: case studyPublication . Barbosa, Mariana Castro; Fernandes, Ângela; Campos, Carlos; Rocha, NunoStroke is the leading cause of acquired adult disability. It can cause multiple impairments and affect multiple domains. These deficits are usually more evident and impairing when performing dual tasks. Dual task is defined as the performance of two or more concurrent tasks simultaneously that require motor and cognitive skills. Recently, tDCS has acquired a growing interest on stroke rehabilitation given its potential to modulate cortical excitability. Evaluate the effects of 9 bihemispheric tDCS sessions over the primary motor cortex in individuals with chronic stroke on dual-task motor performance. In this study case, subject participated in 9 sessions of 20 minutes of bihemispheric tDCS, followed by his traditional rehabilitation activities. Participant was submitted to 4 evaluation moments. The following assessment tools were used: sociodemographic and clinical questionnaire, Mini Mental State Examination, Fugl-Meyer Assessment of Motor Recovery after Stroke, Verbal Fluency Test, Digit Span, Jamar Hydraulic Hand Dynamometer, Timed Up and Go (TUG), Functional Reach Test (FRT), Box and Block Test (BBT) e Stroke Upper Limb Capacity Scale (SULCS). When compared baseline and final assessment results, the participant showed better results under dual task in the BBT, with an improvement of 100% of blocks transferred with the paretic hand and 125% in the non-paretic hand. In TUG, the participant showed better results under dual task, reducing the time to complete the task in 28,69%. No FRT, results improved in single task, 71,41%, with slight changes in dual task. In the Jamar Hydraulic Hand Dynamometer, a slight reduction was registered in both single and dual task. This reduction was smaller under dual task, -0,42%. Results show that combining bihemispheric tDCS with conventional rehabilitation techniques may have a positive effect in dual-task motor performance.
