  • Oral Motricity in preschool children with speech sound disorders: preliminary study
    Publication . Pós de Mina, Sónia; Martins, Fernando; Guimarães, Isabel
    Introduction: Speech Sound Disorders (SSD) is a developmental disorder for which sensorimotor and cognitive-linguistic aspects contribute. These include perceptive capacity, phonological and articulatory representation of the language impairing the speech segments, and the phonotactic and prosodic elements, resulting in different degrees of intelligibility. Aim: Verify the existence of differences in oral motricity according to age and the diagnosis of SSD. Methods: Case-control study with 107 children with typical development and SSD matched for age (in months), between 4 and 5;11. The evaluation was carried out with the PAOF-2 (Protocolo de Avaliação OroFacial, versão 2) (Guimarães et al., 2021). The statistical analysis of the two domains of PAOF-2 (Structure and Mobility) was performed using the Mann- Whitney test. Results: There are no statistically significant differences between the groups in the structure domain at 4 (U=236.5, p=0.182) and 5 (U=344.5, p=0.578) years of age. In the mobility domain, children aged five years old with SSD have significantly lower performance than children without SSD in diadochokinetic oral movement (pá-tá-ká) (U=227.00 p=0.005). Preliminary data point to an evolution in the orofacial motricity of children with and without SSD, but children with SSD present a different evolution with a lower magnitude than children without SSD. All male children with SSD perform worse than female children. Conclusions: The performance of oral diadochokinesia in 5-year-old children with PSF is significantly lower than in 5-year- old children without PSF. The oromotor development pattern of children with PSF is different from that of children without PSF.

  • Sistema de aquisição e registo de sinais biomédicos baseado numa plataforma de desenvolvimento open-source de baixo custo
    Publication . Jardan, Daniel; Gil, João; Martins, Fernando; Ferreira, Lino; Fonseca-Pinto, Rui
    Este artigo apresenta um sistema de aquisição e registo de sinais biomédicos baseado na plataforma desenvolvimento open-source Arduino. O sistema tem associado um cartão de memória para registo de dados, bem como um acelerómetro que indica a atividade/postura do paciente. É utilizado um módulo de comunicação Blue- tooth para ligação a um dispositivo móvel (smartphone e tablet) de forma a permitir a parametrização, o comando do sistema de aquisição e a monitorização em tempo real dos dados adquiridos. Estes dados foram usados para calcular o balanço vago-simpático associado a tarefas específicas do dia-a-dia.
