- 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.
- Gamification in stroke rehabilitationPublication . da Silva Marques, António; Caldas, Helena Maria Martins; Barbosa, Mariana Castro; Soares, Luís Miguel Brazão; Ribeiro, Maria Inês Dias; Simões-Silva, VitorStroke rehabilitation aims to improve patients’ abilities to realize daily life activities and, consequently, regain their self-confidence and improve independence and quality of life. Gamification can be defined as the application of game-design elements, dynamics, and principles such as competition, narratives, point-scoring, and awards in non-game contexts, including rehabilitation. It has emerged as a therapeutic alternative or complement to traditional rehabilitation to make motor practice more intense and increase a person’s motivation, interest, and satisfaction by bringing meaningful and intrinsically motivational playful experiences. Compared to the same amount of conventional therapy, gamification can increase the number of movements and involve safe and intensive rehabilitation exercises, essential for a successful rehabilitation process.
