Contextualização: A fibromialgia (FM) parece limitar o desempenho fÃsico, e a realização de atividades da vida diária (AVDs)
pode exacerbar a dor e o esforço percebido nesses pacientes. Objetivos: Comparar o desempenho do teste de caminhada de
6 minutos (TC6) entre pacientes com FM e controles e verificar relações entre esse desempenho com o impacto na qualidade
de vida, na realização de tarefas da vida diária e no nÃvel de atividade fÃsica. Métodos: Participaram do estudo 19 mulheres
com FM e 20 mulheres saudáveis. Realizou-se o TC6 e, durante o teste, foram mensuradas a intensidade de dor e a percepção
subjetiva de esforço (PSE). Foram aplicados o Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ)
e o International Physical Activity Questionnaire (IPAQ). Resultados: O grupo de mulheres com FM percorreu menor distância no
TC6 (pacientes: 473,52±77,84 m versus controles: 541,75±85,62 m; p=0,02). Para o grupo de pacientes houve correlações entre a
distância caminhada e o questionário FIQ (r=-0,46; p=0,05), o HAQ (r=-0,49; p=0,03) e o consumo de oxigênio (r=0,78; p<0,01) e
entre o HAQ e o consumo de oxigênio (r=-0,52; p=0,02). Durante o teste, as mulheres com FM apresentaram aumento da intensidade
dolorosa e da PSE, o que não ocorreu no grupo controle. Conclusões: Mulheres com FM apresentaram comprometimento da
capacidade funcional e exacerbação da dor e esforço durante o TC6.
Background: Fibromyalgia has been association with physical performance limitations. Additionally, activities of daily living have been
reported to be directly associated with the exacerbation of pain and perceived exertion in this patient population. Objectives: To compare
the performance of a 6-minute walk (6MWT) test in patients with fibromyalgia and controls and to evaluate the relationship between test
performance and quality of life, limitations of activities of daily living and physical activity level. Methods: The study included 19 women
with fibromyalgia (FM) and 20 healthy controls (CG). A 6MWT was conducted and pain intensity and perceived effort (PE) were assessed
during the test. In addition, Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ) and International Physical
Activity Questionnaire (IPAQ) were applied. Results: The fibromyalgia group walked significantly shorter distances when compared to
the control group (FM: 473.52±77.84 m vs. CG: 541.75±85.62 m; p=0.02). In the fibromyalgia group, there was a negative correlation
between distance in 6MWT and FIQ (r=-0.46; p=0.05), HAQ (r=-0.49; p=0.03) and oxygen consumption (r=0.78; p<0.01). There was
also a correlation between HAQ and oxygen consumption (r=0.52; p=0.02). Participants with fibromyalgia had higher pain intensity and
perceived effort during the test when compared to the control group. Conclusions: Women with fibromyalgia had greater impaired of
functional capacity, exacerbation of pain and exertion during the 6MWT when compared to healthy women.
