Resumo:
Apesar de marcadas por contextos históricos e culturais distintos, é possível observar nas obras de dois dos autores mais significativos da África do Sul e de Moçambique, Zakes Mda e Mia Couto respectivamente, perspectivas semelhantes no que diz respeito à recuperação das memórias históricoculturais e à sua contribuição para a construção e compreensão das identidades pós-coloniais. Através da ficção, Zakes Mda e Mia Couto combinam a ligação da História a factos concretos com a necessidade de revelação associada à memória, criando assim espaços importantes para a discussão de algumas das mais complexas questões colocadas às identidades pós-coloniais. Para além dos contextos políticos, culturais e históricos que caracterizam e distinguem as literaturas sul-africana e moçambicana, tanto Zakes Mda como Mia Couto assumem nas suas obras a necessidade de analisar as identidades pós-coloniais contemporâneas dos dois países através da recuperação das suas memórias históricas.

Nervous system disorders are associated with cognitive and motor deficits, and are responsible for the highest disability rates and global burden of disease. Their recovery paths are vulnerable and dependent on the effective combination of plastic brain tissue properties, with complex, lengthy and expensive neurorehabilitation programs. This work explores two lines of research, envisioning sustainable solutions to improve treatment of cognitive and motor deficits. Both projects were developed in parallel and shared a new sensible approach, where low-cost technologies were integrated with common clinical operative procedures. The aim was to achieve more intensive treatments under specialized monitoring, improve clinical decision-making and increase access to healthcare. The first project (articles I – III) concerned the development and evaluation of a web-based cognitive training platform (COGWEB), suitable for intensive use, either at home or at institutions, and across a wide spectrum of ages and diseases that impair cognitive functioning. It was tested for usability in a memory clinic setting and implemented in a collaborative network, comprising 41 centers and 60 professionals. An adherence and intensity study revealed a compliance of 82.8% at six months and an average of six hours/week of continued online cognitive training activities. The second project (articles IV – VI) was designed to create and validate an intelligent rehabilitation device to administer proprioceptive stimuli on the hemiparetic side of stroke patients while performing ambulatory movement characterization (SWORD). Targeted vibratory stimulation was found to be well tolerated and an automatic motor characterization system retrieved results comparable to the first items of the Wolf Motor Function Test. The global system was tested in a randomized placebo controlled trial to assess its impact on a common motor rehabilitation task in a relevant clinical environment (early post-stroke). The number of correct movements on a hand-to-mouth task was increased by an average of 7.2/minute while the probability to perform an error decreased from 1:3 to 1:9. Neurorehabilitation and neuroplasticity are shifting to more neuroscience driven approaches. Simultaneously, their final utility for patients and society is largely dependent on the development of more effective technologies that facilitate the dissemination of knowledge produced during the process. The results attained through this work represent a step forward in that direction. Their impact on the quality of rehabilitation services and public health is discussed according to clinical, technological and organizational perspectives. Such a process of thinking and oriented speculation has led to the debate of subsequent hypotheses, already being explored in novel research paths.
