A Comparison of Physical Functional Performance and Strength in Women With Fibromyalgia, Age- and Weight-Matched Controls, and Older Women Who Are Healthy

Background and Purposes. The purpose of this study was to compare functionality and strength among women with fibromyalgia (FM), women without FM, and older women. Subjects. Twenty-nine women with FM (age [X̅±SD]=46±7 years), 12 age- and weight-matched women without FM (age=44±8 years), and 38 older women who were healthy (age=71±7 years) participated. Methods. The Continuous Scale–Physical Functional Performance Test (CS-PFP) was used to assess functionality. Isokinetic leg strength was measured at 60°/s, and handgrip strength was measured using a handgrip dynamometer. Results. The women without FM had significantly higher functionality scores compared with women with FM and older women. There were no differences in functionality between women with FM and older women. Strength measures for the leg were higher in women without FM compared with women with FM and older women, and both women with and without FM had higher grip strengths compared with older women. Discussion and Conclusion. This study demonstrated that women with FM and older women who are healthy have similar lower-body strength and functionality, potentially enhancing the risk for premature age-associated disability.
