fibromyalgia only vs fibromyalgia patients with co-occuring ME and CFS
as do Dr. Natelson and Drs. Light. This variable may account for
differing results in fibromyalgia studies. As well, this study used
self-report instruments rather than objective measures. This may be in
part because it is difficult to measure pain objectively for example.

Abstract
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=B177.84 m vs. CG: 541.75=B185.62
m; p=3D0.02). In the fibromyalgia group, there was a negative
correlation between distance in 6MWT and FIQ (r=3D-0.46; p=3D0.05), HAQ
(r=3D-0.49; p=3D0.03) and oxygen consumption (r=3D0.78; p<0.01). There was
also a correlation between HAQ and oxygen consumption (r=3D0.52;
p=3D0.02). 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.
