Abstract(s)
A investigação tem demonstrado a utilidade do mindfulness na dor crónica. A sua utilidade na dor aguda tem sido menos estudada. Estudá-lo pode ser relevante para o desenvolvimento de estratégias terapêuticas no contexto de cuidados de saúde primários e em situações de dor aguda. Este estudo teve como objetivo avaliar a eficácia do mindfulness na redução da intensidade da dor aguda induzida experimentalmente, o efeito da interação do sexo e se a intensidade da dor no pré-teste e a alocação à condição experimental são preditores da magnitude da mudança na intensidade da dor entre o pré e pós-teste. Este é um estudo experimental prospetivo com dois braços paralelos. Uma amostra de 67 indivíduos adultos saudáveis foi submetida a dois ciclos de Cold Pressor Arm Wrap. Os participantes na condição experimental escutaram uma gravação de 20 minutos de indução de mindfulness. Os participantes responderam a medidas de intensidade de dor no pré e pós-teste. Os resultados mostram que não houve um efeito da alocação à condição e do sexo na intensidade de dor. A intensidade da dor reportada no pré-teste foi um preditor significativo da magnitude da mudança na intensidade de dor. Estes resultados sugerem que deverão ser adotadas medidas de gestão eficaz da dor aguda em estádios iniciais, desenvolvendo estratégias analgésicas não medicamentosas e que a investigação futura deveria replicar este estudo em amostras maiores e mais equilibradas.
Research has shown the usefulness of mindfulness in chronic pain. Its usefulness in acute pain has been less studied. Studying it can be relevant for the development of therapeutic strategies in the context of primary health care and in situations of acute pain. This study aimed to evaluate the effectiveness of mindfulness in reducing the intensity of experimentally induced acute pain, the effect of the interaction of sex and whether pre-test pain intensity and allocation to the experimental condition are predictors of the magnitude of change in pain intensity between pre and post-test. This is a prospective experimental study with two parallel arms. A sample of 67 healthy adult individuals underwent two cycles of Cold Pressor Arm Wrap. Participants in the experimental condition listened to a 20-minute recording of mindfulness induction. Participants responded to pre and post-test pain intensity measurements. Results show that there was no effect of allocation to condition and sex on pain intensity. Pain intensity reported in the pre-test was a significant predictor of the magnitude of change in pain intensity. These results suggest that effective acute pain management measures should be adopted at early stages, developing non-drug analgesic strategies, and future research should replicate this study in larger and more balanced samples.
