Abstract(s)
A Fibromialgia é uma condição de dor cronica generalizada associada a alterações
no processamento central e periférico da dor, bem como a alterações no processamento
dos estados internos, ou seja, na interoceção. Alguns estudos referem a existência de
elevada variabilidade nos relatos de dor nesta condição, o que pode dificultar o
diagnóstico e tratamento da dor. Recentemente foi desenvolvido o Focused Analgesia
Selection Test (FAST) um procedimento experimental para avaliar a variabilidade nos
relatos de dor, ou seja, a relação entre as diferentes intensidades de estímulos aplicados e
os relatos de dor reportados pelos indivíduos.
O objetivo do presente estudo é estudar a relação entre a capacidade de ser
exato/preciso na avaliação da dor e a capacidade de ser preciso na avaliação de outras
sensações corporais na FM. Foram recrutados 30 participantes com FM, aos quais se
aplicou o protocolo experimental para avaliação da dor que consistiu na avaliação da
variabilidade da dor experimental (FAST), da sensibilidade à dor através da avaliação de
limiares e tolerância à dor em diferentes modalidades (elétrica, térmica, pressão), assim
como a capacidade interocetiva, avaliada através da tarefa do batimento cardíaco e o
MAIA, e avaliação de características clínicas com uso do FIQ, BPI e HADS. Os
resultados mostram que a capacidade de ser preciso a reportar a dor não se correlaciona
com a capacidade de ser preciso na avaliação dos batimentos cardíacos nem com a
sensibilidade interocetiva pelo individuo. Também não se encontram relações entre a
interocepção e a sensibilidade à dor. As caraterísticas clínicas e psicológicas dos
individuos podem estar associadas a um aumento da sensibilidade interocetiva, mais
especificamente em individuos com maior capacidade de confiar no corpo e de não se
distrair dos seus estados, revelam menos serevidade de dor e menor impacto no
funcionamento físico pela fibromialgia e menor ansiedade e depressão. Mais estudos
serão necessários para clarificar estas relações e melhorar a compreensão das
competências envolvidas nos relatos de estados do corpo, aspeto que é central na
avaliação e tratamento de doentes com dor crónica.
Fibromyalgia is a condition of generalized chronic pain associated with changes in the central and peripheral processing of pain, as well as changes in the processing of internal states, that is, in the interception. Some studies report the existence of high variability in pain reports in this condition, which may hinder the diagnosis and treatment of pain. Recently, the Focused Analgesia Selection Test (FAST) was developed, an experimental procedure to evaluate the variability in pain reports, that is, the relationship between the different intensities of stimuli applied and the reports of pain reported by the individuals. The aim of this study is to study the relationship between the ability to be accurate/accurate in pain assessment and the ability to be precise in the evaluation of other body sensations in FM. Thirty participants with FM were recruited, to whom the experimental protocol was applied to assess pain, which consisted of the evaluation of experimental pain variability (FAST), pain sensitivity through the evaluation of thresholds and pain tolerance in different modalities (electrical, thermal, pressure), as well as the interoceptive capacity, evaluated through the task of heartbeat and MAIA, and evaluation of clinical characteristics with the use of FIQ, BPI and HADS. The results show that the ability to be accurate in reporting pain does not correlate with the ability to be accurate in assessing heart rate or with the interoceptive sensitivity reported by the individual. There is also no relationship between interoception and sensitivity to pain. The clinical and psychological characteristics of individuals may be associated with an increase in interoceptive. More specifically with a greater ability to trust their bodies and not to be distracted from their states reveal less severe pain, less impact on physical functioning due to fibromyalgia and less anxiety and depression. Further studies are needed to clarify these relationships and improve understanding of the skills involved in reporting body states, which is central to the assessment and treatment of patients with chronic pain.
