“…These results support previous findings on the association between muscle strength (as assessed with either isometric [10], isokinetic [9,10], or functional fitness tests [7,8]) and pain. The association of flexibility with pain in FM patients has received limited attention.…”

“…By contrast, Hooten et al (10) reported that peak VO 2 was not associated with PPT in FM patients. Lower-body muscle strength seems to be associated with PPT (7,10) and inversely related to TPC (8) in FM patients. However, Henriksen et al (9) observed that the association between knee muscle strength and TPC in these patients was weak.…”

“…Soriano-Maldonado et al (11) revealed that peak oxygen uptake (peak VO 2 ) was inversely associated with PPT but not with clinical pain in women with FM (11). By contrast, Hooten et al (10) reported that peak VO 2 was not associated with PPT in FM patients. Lower-body muscle strength seems to be associated with PPT (7,10) and inversely related to TPC (8) in FM patients.…”

“…Several studies examined the association of different components of physical fitness with pain in FM patients, with mixed findings (7)(8)(9)(10)(11). Carbonell-Baeza et al (8) observed that aerobic fitness (the distance walked in the 6-minute walk test) was inversely related to pain (as measured by tender points count [TPC] and pressure-pain threshold [PPT]) in women with FM.…”

Objective. This population-based cross-sectional study aimed to characterize the association of different components of physical fitness with pain levels, pain-related catastrophizing, and chronic pain self-efficacy in women with fibromyalgia (FM). Methods. A total of 468 women with FM participated. The experience of pain was assessed with different tools (algometry, a numeric rating scale [revised FM impact questionnaire], a visual analog scale, and the bodily pain subscale on the Short Form 36 health survey). We also assessed pain-related catastrophizing and chronic pain self-efficacy. Physical fitness was assessed with performance-based tests (Senior Fitness Test battery and handgrip dynamometry). A standardized composite score was computed for each component of physical fitness (aerobic fitness, muscle strength, flexibility, and motor agility), and their average comprised a clustered global fitness profile. Results. Overall, higher physical fitness was consistently associated with lower levels of pain, lower pain-related catastrophizing, and higher chronic pain self-efficacy (regardless of the pain assessment method and the fitness test evaluated). Muscle strength and flexibility were independently associated with pain (P < 0.005 for both), and participants with high muscle strength plus high flexibility (combined effect) had the lowest levels of pain in this population. Aerobic fitness and flexibility were independently associated with pain-related catastrophizing (P < 0.001 for both) and chronic pain self-efficacy (P < 0.001 for both), and participants with high flexibility plus high aerobic fitness (combined effect) had the best catastrophizing and self-efficacy profiles. Conclusion. Our results suggest that higher physical fitness is associated with lower levels of pain, lower pain-related catastrophizing, and higher chronic pain self-efficacy in women with FM. These results might have implications for future intervention studies in this population.

BackgroundThe associations between pain, lower extremity strength, and aerobic conditioning have not been widely investigated in adults with fibromyalgia (FM). The principle objective of this study was to investigate the relationship between pain severity and knee strength in patients seeking treatment for FM. A secondary objective was to investigate the relationship between pain scores and aerobic conditioning.MethodsThree measures of knee strength (isokinetic extensor, isokinetic flexor, isometric extensor) were quantified in the dominant leg of 69 adults with FM using a dynamometer at speeds of 60 degrees per second (60°/s) and 180°/s. Peak oxygen uptake (VO2) was assessed using a cycle ergometer, and pain was assessed using the pain severity subscale of the Multidimensional Pain Inventory.ResultsIn univariable linear regression analyses using pain severity as the dependent variable, lesser values of isokinetic knee extensor strength at 60°/s (P=0.041) and 180°/s (P=0.010), isokinetic knee flexor strength at 60°/s (P=0.028) and 180°/s (P=0.003), and peak VO2 uptake (P=0.031) were predictive of greater pain severity scores. In multiple variable linear regression models adjusted for age, sex, body mass index, and opioid use, the following associations retained statistical significance; isokinetic knee extensor strength at 60°/s (P=0.020) and 180°/s (P=0.003), isokinetic knee flexor strength at 60°/s (P=0.015) and 180°/s (P=0.001), and peak VO2 uptake (P=0.014). However, no significant associations were found between pain severity and isometric knee extensor strength.ConclusionThe main findings from this study were that lesser values of isokinetic knee strength and peak VO2 uptake were predictive of greater pain severity scores. These results build on the findings of previous investigations, but ongoing research is needed to further characterize the effects of strength and peak VO2 uptake on the pathophysiology of FM.
