Introdução: A dor está presente em várias doenças e tem um impacto significativamente
negativo na qualidade de vida do sujeito. As dificuldades em definir o conceito, relatar
com precisão e avaliar a dor têm sido consideradas os principais motivos do fracasso dos
ensaios clínicos em avaliar a eficácia de novos analgésicos. Neste estudo é explicado o
conceito e a história da dor, a neuro modulação e as vias ascendentes e descendentes, os
diferentes tipos de classificação da dor, o impacto da memória no processamento da dor,
as medidas mais comuns utilizadas na avaliação da dor, a forma como as pessoas
percecionam de forma diferente a dor e os impactos que as variáveis individuais têm no
relato das habilidades de dor.
Objetivos: Este estudo baseia-se nos seguintes objetivos: comparar as diferenças na
variabilidade experimental do FAST (medido através do R², ICC, CoV) nos dois grupos
culturais (Portugal e Israel; estudar a relação entre as diferenças individuais (medidas
através de questionários) e as diferenças na variabilidade obtida através do FAST (medido
através do R², ICC, CoV); estudar a relação entre as diferenças demográficas (idade, sexo,
anos de escolaridade, estado civil e IMC) e as diferenças na variabilidade obtida através
do FAST (medido através do R², ICC, CoV); e, por último, correlacionar as relações entre
a capacidade de memória a curto prazo (medida através da tarefa Memória de Dígitos) e
a variabilidade experimental dos relatos de dor do FAST (medido através do R², ICC,
Cov).
Método: Este estudo retrospetivo envolveu a análise dos resultados de 452 indivíduos
saudáveis a quem foi aplicado, em dois laboratórios, o teste de seleção de analgesia focada
(FAST) que permite medir a variabilidade nos relatos de dor induzida por estímulos
experimentais. Foi obtida informação demográfica (idade, género, escolaridade, estado
civil e IMC) e de características individuais, através dos seguintes questionários: SCS-R;
PSQ; PCS; LOT; BAQ; HADS; MAIA. E, ainda, foi avaliada a memória de curto-prazo,
através do teste de Memória de Dígitos.
Resultados: Os dados recolhidos mostraram que há elevada dispersão nos resultados da
variabilidade nos relatos de dor. Há associações entre o género, o estado civil e a
catastrofização da dor comparativamente com os resultados no FAST e também foram
encontradas algumas correlações entre Digit Span e os dois locais do estudo e com os
resultados do FAST.Conclusão Final: Os resultados sugerem que o género, a cultura e as competências de
memória de curto-prazo podem ter impacto na variabilidade nos relatos de dor induzida
experimentalmente. Uma investigação mais aprofundada sobre estas relações revela-se
necessária para uma melhor compreensão dos processos envolvidos na avaliação de
intensidade de dor.
Introduction: Pain is present in several diseases and has a significant negative impact on the quality of life. The difficulties in defining the concept, accurately reporting, and assessing pain has been considered the main reasons for the failure of clinical trials to evaluate the effectiveness of new analgesic medications. In this study it is explained the concept and history of pain, the neuromodulation and the ascending as descending pathways, the different types of classification of pain, the impact of the memory while processing pain, the most common forms of pain assessment, the way people perceive differently the pain and the impacts that individual variables have in reporting pain skills. Objectives: This study is based on the following objectives: the differences in the experimental variability of FAST (measured through R², ICC, CoV) in the two cultural studies (Portugal and Israel; to study a relationship between individual differences (measured through the comparative groups) and how differences in the variability obtained through the FAST (measured through the R², ICC, CoV); to study a comparison between the demographic differences (age, sex, years of schooling, marital status, and BMI) and how differences in the accessible variability of the FAST ( Mean of the R², ICC, through CoV); and, using correlating the relationships between the last short-term memory capacity (measured through the Digit Memory task) and the experimental variability of FAST pain reports (measured from the R², ICC, Cov). Method: This retrospective study involved the analysis of the results of 452 healthy individuals to whom, in two laboratories, the focused analgesia selection test (FAST) was applied, which allows the measurement of variability in reports of pain induced by experimental stimuli. Demographic information (age, gender, education, civil status, BMI) and individual characteristics were obtained through the following questionnaires: SCS-R; PSQ; PCS; LOT; BAQ; HADS; MAIA. Furthermore, short-term memory was evaluated through the Digit Memory test. Results: The collected data showed that there is high dispersion in the results of variability in pain reports. There are associations between gender, civil status and pain catastrophizing compared to the FAST results and some correlations were also found between Digit Span and the two study sites and with the FAST results. Final Conclusion: The results suggest that gender, culture, and short-term memory skills may impact the variability in reports of experimentally induced pain. Further investigation of these relationships is necessary for a better understanding of the processes involved in pain intensity assessment.
