- Handgrip strength time profile and frailty: an exploratory studyPublication . Urbano, Diana; Restivo, Maria Teresa; Barbosa, Manuel Romano; Fernandes, Ângela; Abreu, Paulo; Chousal, Maria de Fátima; Coelho, TiagoThis study aims to explore the use of force vs. time data obtained from an isometric handgrip test to match a frailty state based on the TFI score. BodyGrip, a novel prototype system, is used for handgrip strength over 10 s time interval tests. A cross-sectional study with a non-probabilistic sample of community-dwelling elderly women was conducted. The force/time data collected from the dominant handgrip strength test, together with the Tilburg Frailty Indicator (TFI) test results, were used to train artificial neural networks. Different models were tested, and the frailty matching of TFI scores reached a minimum accuracy of 75%. Despite the small sample size, the BodyGrip system appears to be a promising tool for exploring new frailty-related features. The adopted strategy foresees ultimately configuring the system to be used as an expedite mode for identifying individuals at risk, allowing an easy, quick, and frequent person-centered care approach. Additionally, it is suitable for following up of the elderly in particular, and it may assume a relevant role in the mitigation of the increase in frailty evolution during and after the imposed isolation of the COVID-19 pandemic. Further use of the system will improve the robustness of the artificial neural network algorithm.
- Impacto do biofeedback na reabilitação motora de pessoas com sequela de lesão neurológica adquiridaPublication . Abreu, Paulo; Restivo, Maria Teresa; Sousa, HelenaNeste trabalho é apresentado o dispositivo instrumentado SHaRe e diversas aplicações informáticas desenvolvidas, na forma de jogos com as quais interatua, que permitem a sua utilização em atividades de reabilitação, nomeadamente, num programa de Terapia Ocupacional. O dispositivo Share, na sua forma de copo, está instrumentado com sensor de força e com sensor inercial. Esta instrumentação do dispositivo associada às aplicações desenvolvidas, permitem dar ao utilizador um feedback da força preensora usada na manipulação do objeto, bem como usar técnicas de visualização aumentada. Estas funcionalidades, juntamente com o uso de aplicações do tipo de jogos, permitem aos utilizadores uma maior motivação com impacto no sucesso das atividades de reabilitação. A utilização do dispositivo SHaRe foi testada em diversos contextos de reabilitação tendo a sua utilidade e versatilidade sido reconhecidas por utilizadores e técnicos.
- Instrumented balance boardPublication . Abreu, Paulo; Chousal, Fátima; Sousa, Helena; Restivo, Maria TeresaA balance board can be a useful tool for increasing stability and balance, which is advantageous for a variety of users, including athletes, elderly people, people recovering from injuries or neurodegenerative diseases, and stroke patients. The majority of these balance boards typically comprise a simple board or platform on a pivot point, without providing any feedback data to the user. The instrumentation of these boards can enlarge the applicability of these boards by providing a way to record user performance and visualize the execution of the exercises with the board. This work will offer a demo to present the prototype of a balance board that was instrumented with an inertial measurement unit (IMU) and microcontroller to provide orientation data. The developed application software allows storing historic data and provides visual and acoustic feedback. This portable prototype is built on top of a commercially available balance board and the user interface runs on a web- based application.
- Positive effects of visual, auditory biofeedback and exergames on physical rehabilitation: A review of SHaRe clinical trialsPublication . Restivo, Maria Teresa; Abreu, Paulo; Sousa, Helena; Rodrigues, JoséThis work discusses the use of an interactive platform for physical rehabilitation, called SHaRe, that was tested in various health conditions, including stroke, multiple sclerosis, limb amputation, and acquired neurological injury. The platform uses visual and sound biofeedback and exergames to engage participants and encourage adherence to rehabilitation programs. Results from studies using the developed platform SHaRe positively impacts hand strength, prosthesis control, and object handling. Participants in all studies reported high levels of satisfaction finding it to be fun and motivating. The telerehabilitation approach was successfully used in two of the studies. Overall, the findings suggest that SHaRe is a promising platform for physical rehabilitation in a variety of physical conditions.
- Serious Game for reading and spelling skillsPublication . Sucena, Ana; Silva, Ana Filipa; Garrido, Cristina; Abreu, Paulo; Carneiro, João Falcão; Restivo, Maria TeresaThis work describes an interactive child-friendly application focused on spelling, intended to promote sensibility to Portuguese orthography. A description of the game and its particularities are given, as well as preliminary results obtained in school environment.
