Resumo: | Stroke is one of the leading causes of disability and death in the world, and rehabilitation is a relevant part of the life of stroke survivors. Physical therapy is necessary to recover some movement during the acute phase, but also to maintain muscle strength and avoid deterioration and weakness during the chronic phase. The global pandemic caused shortages of rehabilitation activities, and Virtual Reality (VR) games could be used as a complementary type of therapy for stroke rehabilitation to be used at home. This dissertation proposes a user study to better understand the needs and preferences of stroke survivors and the development of game prototypes to better ascertain the potential of VR-based serious games. With this goal, a Questionnaire and a Focus Group were done with survivors, and based on their results, two VR-based game prototypes were developed, focused on the movements that survivors need to perform as well as providing an equivalent to Mirror Therapy. This study found that stroke survivors in chronic stage are more interested in applications based on real-world activities, especially activities they used to perform before the onset symptoms. Negative feedback is also an issue they prefer to avoid based on mental health conditions commonly associated with stroke. The game prototypes were tested concerning usability and were scored high with healthy participants on the System Usability Scale when performed normally, but low when their movements were mirrored, though perhaps survivors are more used to this kind of exercise. The performance of the game prototypes needs improvement, but they were considered easy to use and to learn. The next step will be an evaluation of the improved versions by stroke survivors. |

A fisioterapia é necessária para recuperar algum movimento durante a fase aguda, mas também para manter a força muscular e evitar a deterioração e fraqueza durante a fase crónica. A pandemia global causou escassez de atividades de reabilitação, e jogos de Realidade Virtual (RV) poderiam ser usados como um tipo complementar de terapia para reabilitação de AVC com o uso em casa. Esta dissertação propõe um Estudo com Utilizadores para melhor compreender as necessidades e preferências de sobreviventes do AVC e o desenvolvimento de protótipos de jogos para melhor averiguar o potencial de jogos sérios baseados em RV. Com este objetivo, um Questionário e um Grupo Focal foram feitos com os sobreviventes e, com base em seus resultados, dois protótipos de jogos baseados em RV foram desenvolvidos, focados nos movimentos que os sobreviventes precisam realizar, além de fornecer um modo equivalente à Terapia do Espelho. Este estudo descobriu que sobreviventes de AVC em estágio crónico estão mais interessados em aplicações baseadas em atividades do mundo real, especialmente atividades que eles costumavam realizar antes do início dos sintomas. O feedback negativo também é um problema que eles preferem evitar com base nas condições de saúde mental comumente associadas ao AVC. Os protótipos do jogo foram testados com base em usabilidade e pontuaram alto com os participantes saudáveis na Escala de Usabilidade do Sistema quando executados normalmente, mas pontuaram baixo quando seus movimentos foram espelhados, embora talvez os sobreviventes estejam mais acostumados a esse tipo de exercício. O desempenho dos protótipos de jogos precisa de melhorias, mas eles foram considerados fáceis de usar e aprender. O próximo passo será a avaliação de versões melhoradas por sobreviventes de AVC.2022-04-26T09:27:21Z2021-12-16T00:00:00Z2021-12-16info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/33729engSerra, Helder Augusto Paraense de Oliveirainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T12:04:52Zoai:ria.ua.pt:10773/33729Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:05:04.819260Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
