Fibromyalgia is a condition characterized by chronic widespread muscle pain and fatigue and associated with significant impairment in perceived function and reduced physical performance.
Chronic pain is
associated with fibromyalgia. Several factors influence pain intensity
experienced with fibromyalgia including the number of body pain areas,
psychological constructs, and response to peripherally applied stimuli. Thus,
in this study the impact of pain and fatigue intensities is a persuasive
consideration in the assessment and treatment of fibromyalgia patients.
Fibromyalgia is a
condition characterized by chronic widespread muscle pain and fatigue and
associated with significant impairment in perceived function and reduced
physical performance. The purpose of this study was to determine the degree to
which pain and fatigue are associated with perceived function and physical
performance in women with fibromyalgia.
Hierarchical
linear regression determined the contribution of pain and fatigue (Numeric
Rating Scale (NRS) for resting, movement and combined) to perceived function
(Fibromyalgia Impact Questionnaire Revised - Function Subscale, FIQR-Function),
Multidimensional Assessment of Fatigue - Activities of Daily Living (MAF-ADL)
and SF-36 Physical Function Subscale (SF-36-PF) and physical performance
(6-Minute Walk Test, 6MWT and Five Time Sit To Stand, 5TSTS) while controlling
for age, body mass index, pain catastrophizing, fear of movement, anxiety, and
depression in women with fibromyalgia (N = 94).
For perceived
function, movement pain and movement fatigue together better predicted
FIQR-function (adjusted R2 = 0.42, p ≤ 0.001); MAF-ADL (adjusted R2 = 0.41,
p ≤ 0.001); and SF-36-PF function (adjusted R2 = 0.34, p ≤ 0.001). For physical
performance measures, movement pain and fatigue together predicted 6MWT
distance (adjusted R2 = 0.42, p ≤ 0.001) and movement fatigue alone predicted
performance time on the 5TSTS (adjusted R2 = 0.20, p ≤ 0.001).
Pain and fatigue
are significantly associated with and explain more than one-third of the
variance in perceived function and physical performance in women with
fibromyalgia.
