- Muscle loading and psychophysical effects of obesity during vertical handling tasksPublication . Colim, Ana; Arezes, Pedro; Flores, Paulo; Monteiro, Pedro; Mesquita, InêsIt has been recognized by many researchers that the prevalence of obesity is a serious public health problem. Several physical problems are associated with obesity, which can negatively affect the individuals’ work performance. In occupational contexts, vertical handling tasks, including lifting and/or lowering loads, are common and produce significant muscle loading. For these reasons, Surface electromyography (EMG) data were collected bilaterally from muscles recruited during these tasks. Additionally, the participants reported physical loading by using the Rated Perceived Exertion scale (RPE). These techniques sought to analyze the physical loading during vertical handling tasks. The obtained results indicate that obesity seem to increase the muscle loading during vertical handling tasks. However, obesity level does not seem to influence the RPE values.
- Effects of low doses of external radiation from 137Cs on Lactuca sativa seedling and Daphnia magna reproductionPublication . Teles, Luís; Henriques, Marta; Santos, Rubim; Barros, PiedadeNaturally occurring cesium exists as a stable isotope 133Cs in the earth crust in granites and in sedimentary rocks. Cesium has very low mobility in soil surfaces.
- Efeitos do tratamento osteopático em indivíduos com Doença Pulmonar Obstrutiva Crónica (DPOC): revisão sistemáticaPublication . Pinheiro, Ana Rita; Paiva, Beatriz; Silva, Bruna; Monteiro, Joana; Sousa, Helena; Campelo, NatáliaA Doença Pulmonar Obstrutiva Crónica (DPOC) é uma doença pulmonar inflamatória crónica, multifatorial, com elevada incidência e prevalência em Portugal e no mundo. A osteopatia tem sido proposta como uma abordagem complementar e segura no tratamento das demais doenças inflamatórias crónicas, inclusive a DPOC. Avaliar os efeitos da intervenção osteopática na sintomatologia, bem-estar e qualidade de vida de indivíduos com DPOC. A pesquisa científica foi realizada no dia 23 de abril de 2022 nas bases de dados Pubmed e Web of Science Core Collection. Foram incluídos somente RCT’s publicados desde 2008. Estes estudos incluíram indivíduos de idade superior a 18 anos com diagnóstico de DPOC, que foram submetidos a intervenção osteopática. A análise dos artigos quanto aos critérios de inclusão e elegibilidade, a extração de dados e a avaliação da qualidade metodológica foi realizada por dois revisores independentes, com intervenção de um terceiro revisor em caso de discordância. A qualidade metodológica foi avaliada recorrendo ao Cochrane Risk of Bias Tool. Nesta revisão, dos 213 resultados obtidos, foram incluídos 4 estudos. Estes apresentaram uma baixa qualidade metodológica com alto risco ou incerto de viés. Num primeiro estudo, em comparação com o grupo controlo, o grupo experimental apresentou um aumento mais significativo da capacidade de exercício (p=0,04) e uma diminuição substancialmente maior do volume residual (p=0,001). Num segundo estudo, o grupo experimental apresentou diminuição significativa (p≤0,05) do fluxo expiratório forçado, do volume de reserva expiratório e da resistência das vias aéreas, e um aumento significativo (p≤0,05) no volume residual, capacidade pulmonar total e na razão desses valores, em comparação com o grupo controlo. Num terceiro estudo, o grupo experimental obteve melhorias significativos nos testes “CAT Questionnaire” (p<0,0005) e “6MWT” (p<0,0038) avaliados no mesmo dia da 4ª sessão de TMO, comparativamente com o grupo controlo. Num último estudo, verificou-se uma melhoria significativa da perceção de dispneia com intervenção osteopática (p=0,04). A presente revisão sistemática demonstrou evidência frágil quanto à eficácia do tratamento osteopático na melhoria da função pulmonar, porém com relatos de melhorias ao nível da sintomatologia, bem-estar e qualidade de vida dos indivíduos com DPOC.
- EEG evidence for mirror neuron system integrity in Down syndromePublication . Ferreira, Laís; Simões-Silva, Vitor; Tavares, Diana; Santos, Rubim; Rocha, NunoUnderstanding and imitating other people’s actions is crucial for social cognition. These skills appear to be supported by the human mirror neuron system. There is contradictory evidence regarding social skills in people with Down Syndrome (DS) and in consequence, regarding the integrity of the mirror neuron system. Although having good social and imitation skills, there is evidence for impairments in interpreting social situations and recognizing emotions. To determine whether there are impairments in the mirroring activity of adults with DS when compared to individuals without DS, by calculating the variation of the suppression of the EEG mu activity.
- Muscle Energy Technique versus PNF: effectiveness on hamstring muscle stretchingPublication . Silva, Paula; Santos, Rubim; Macedo, RuiAlthough PNF´s Contract-Relax with Antagonist Contraction (CRAC) and Muscle Energy Techniques (MET) increase muscle flexibility and Range of Motion (ROM), few studies compared their effectiveness. They share several features but one major difference, the intensity of muscle contraction prior to stretch, perceived maximum in CRAC, and a percentage of the perceived maximum in the MET. Confirm if CRAC and MET are effective in stretching the hamstring muscle in the short term, if both are determine the most effective.
- Differences in Mismatch Negativity (MMN) response to Pure-tone and Speech sounds in normal subjects: an additional explanationPublication . Tomé, David; Barbosa, Fernando; Marques-Teixeira, JoãoThe relation of automatic auditory discrimination, measured with MMN, with the type of stimuli has not been well established in the literature, despite its importance as an electrophysiological measure of central sound representation. In this study, MMN response was elicited by pure-tone and speech binaurally passive auditory oddball paradigm in a group of 8 normal young adult subjects at the same intensity level (75 dB SPL). The frequency difference in pure-tone oddball was 100 Hz (standard = 1 000 Hz; deviant = 1 100 Hz; same duration = 100 ms), in speech oddball (standard /ba/; deviant /pa/; same duration = 175 ms) the Portuguese phonemes are both plosive bi-labial in order to maintain a narrow frequency band. Differences were found across electrode location between speech and pure-tone stimuli. Larger MMN amplitude, duration and higher latency to speech were verified compared to pure-tone in Cz and Fz as well as significance differences in latency and amplitude between mastoids. Results suggest that speech may be processed differently than non-speech; also it may occur in a later stage due to overlapping processes since more neural resources are required to speech processing.
