Abstract(s)
A Hipertensão Arterial apresenta-se como uma doença crónica e multifatorial altamente instalada na sociedade e, mesmo apesar da disponibilidade de terapêutica anti-hipertensiva e aconselhamento dos profissionais de saúde, mostra-se ainda relutantemente prevalente. É especificamente neste contexto que pode vir a inserir-se a terapia musical que, para além da vasta panóplia de benefícios comprovados que patenteia, revela também um elevado potencial para reduzir a Pressão Arterial.
O principal objetivo deste trabalho de investigação é aferir se o impacto do mesmo trecho musical, apresentado por meio de gravação e na forma de música “ao vivo”, revela diferenças a curto prazo nos parâmetros fisiológicos estudados: Pressão Arterial e Frequência Cardíaca.
Para o efeito, selecionou-se uma amostra de 40 indivíduos, repartida em dois grupos, que foram sujeitos a duas abordagens musicais: a primeira exposição musical, gravada, foi comum a ambos os grupos; a segunda exposição foi dividida em música gravada e música “ao vivo”, conforme o grupo de estudo. Recorreu-se a um sistema de monitorização contínua da Pressão Arterial digital, bem como ao esfigmomanómetro (digital) para efeitos comparativos.
Os resultados evidenciam o facto de a música sedativa/relaxante produzir uma diminuição significativa a níveis estatísticos, a curto prazo, nos parâmetros fisiológicos estudados. Por outro lado, as diferenças médias dessa influência não se mostraram estatisticamente significativas ao comparar uma exposição de música gravada com outra de música “ao vivo”. Apesar disso, observou-se que a probabilidade de ocorrer uma descida dos parâmetros fisiológicos em análise após a segunda abordagem musical foi superior à probabilidade dessa redução não ocorrer. No mesmo sentido, embora o número de pessoas que experienciou uma descida da Pressão Arterial Sistólica entre o início do primeiro e o fim do segundo trecho musicais fosse semelhante em cada um dos grupos de estudo, verificou-se que, após a primeira abordagem de música gravada, o grupo que foi sujeito a música “ao vivo” revelou um menor número de reduções desta medida comparativamente ao grupo que foi novamente sujeito a música gravada.
Arterial Hypertension presents itself as a highly installed chronic and multifactorial disease in society and, despite the acessibility of antihypertensive therapy or the advice of health professionals, still persists reluctantly prevalent. It’s in this context that music therapy may step into the scene as a potential resource to reduce Blood Pressure, among it’s wide range of proven benefits. The main objective of this research is to determine the impact, on a short-term basis, of the same music excerpt, presented as a recording or as “live” music, in the variation of the physiological parameters regarded in this study: Blood Pressure and Heart Rate. For this purpose, we selected a sample of 40 individuals, which were distributed into two equal-sized groups, and exposed them to two musical approaches. The first recorded musical exposure was the same for both groups. As for the second exposure, it was divided into recorded music and "live" music depending on the group. We used a continuous monitoring system of digital Blood Pressure, having also used, for comparative purposes, the measures of a digital sphygmomanometer. The results show that sedative/relaxing music produces a statistically significant decrease, on a short term basis, of the physiological parameters taken into analysis. On the other hand, the mean diferences of that decrease were not statistically significant when we compare the exhibition of recorded music with "live" music. Nevertheless, it was observed that, after the second musical approach, the physiological parameters have a higher probability of decreasing than increasing. Similarly, although the number of people who experienced a decline in sistolic blood pressure between the beginning of the first and the end of the second musical excerpt was similar in each of the study groups, it was found that after the first excerpt of recorded music, the group which listened to "live" music revealed fewer reductions of this measure compared to the group which listened again to recorded music.
