Comparison of functional and isokinetic performance between healthy women and women with fibromyalgia.

BACKGROUND

Fibromyalgia is a condition that predominantly affects women and is characterized by chronic pain. As a consequence, it has been suggested that there is a decrease in muscle strength, a prime component of physical fitness, and thus a reduction in functional performance. Therefore, it is necessary to perform a complete and reliable physical evaluation of functional performance. The aim of this study was to compare the functional and isokinetic performance between women with fibromyalgia and healthy women.

METHODS

This is a cross-sectional study that evaluated 40 women divided into 2 groups: Healthy Group (HG) (n = 20); Fibromyalgia Group (FG) (n = 20), aged between 30 and 50 years. The individuals were submitted to an evaluation of functional performance through the following tests: Timed Up and Go (TUGT), Chair Stand Test, 6-Minute Walk test (6MWT), Sit and Reach Test, and Isokinetic performance of the knee extensor and flexor groups. Statistical analysis was performed by the statistical SPSS 22.0 software for Windows.

RESULTS

A lower index was observed in the 6-min Walk Test (p < 0.001), Chair Stand Test (p < 0.001), and VO Peak (p < 0.001) for FG. There were no significant differences in isokinetic performance (p > 0.05).

CONCLUSIONS

The results point to lower functional performance in individuals with fibromyalgia when compared to healthy individuals of the same age and physical activity level. Therefore, it is evident that performing therapeutic exercises of different modalities to improve the functional performance of patients with FM is important.
