AB0906 RELATIONSHIP BETWEEN FIBROMYALGIA AND TRUNK MUSCLE PERFORMANCE

Abstract

Background: Muscle performance is adversely affected by pain, fatigue and low aerobic capacity in fibromyalgia syndrome(FMS). Objectives: We compared trunk muscle performance of women with FMS and healthy individuals who have similar age and body mass index (BMI). Methods: A total of 37 women with FMS and 32 healthy women were included this study. The demographic and clinical characteristics of the participants such as age, height, weight, body mass index (BMI), occupations, exercise habits were recorded. In semi-standing position with isokinetic dynamometer (BIODEX) at 60 ° -90 ° -120 °/second (s) angular velocities, trunk flexor and extensor muscle performances were evaluated. Flexor (flex) peak torque (PT), extensor (ext) PT values and flex/ext PT ratio (%) were noted. Results: The mean age was 43.9 ± 8.1 years in FMS group and 43,7 ± 6,7 in control group. The mean BMI was 27.5 ± 4.19 in FMS group and 26.4 ± 4.08 in control group. There was no significant difference between the groups in terms of age and BMI (p> 0.05). As a result of isokinetic measurements of trunk muscles, extensor PT values were found significantly lower in women with FMS than C group at all three angular velocities (p <0.05). The flexor PT values also were lower in FMS group but no statistically significance in flexor PT values between the groups (p>0.05). When flexor/extensor PT ratio was compared, it was seen that this ratio increased in the FMS group. Conclusion: There are many studies in the literature assessing upper and lower extremity muscle performances in FMS (1-2). To our knowledge, we first evaluated trunk muscle performances of patients with FMS and we found that trunk muscles, especially extensors, were significantly weaker in FMS group. As a result, in treatment of FMS, there is a need for more comprehensive randomized controlled studies showing the importance of strengthening exercises to improve trunk muscle performance.
