THU0714-HPR RELATIONSHIP BETWEEN TRUNK POSITION SENSE, TRUNK MUSCLE ENDURANCE AND BALANCE IN WOMEN WITH FIBROMYALGIA SYNDROME

Abstract

Background Position sense plays a fundamental role in human movement which is crucial for daily activities, exercise and sports [1]. Trunk endurance and balance were also integrated part of normal functional movements. Decreased balance and trunk muscle endurance were reported in women with fibromyalgia syndrome (FMS) [2]. However, to our knowledge, the relationship between trunk position sense, trunk muscle endurance and balance has not been studied in women with FMS. Objectives This study aimed to determine the relationship between trunk position sense, trunk muscle endurance and balance in women with FMS. Methods Women with FMS (n: 25, age: 42.88±11,66 years, body mass index: 25.69±3.48 kg/m²) were recruited. Trunk position sense was assessed with digital inclinometer by trunk reposition errors in which higher scores indicates poor trunk position sense [3]. Trunk flexor, extensor, dominant and non-dominant lateral side muscle endurance with McGill’s trunk muscle endurance tests [4] in seconds and balance with the Mini-Balance Evaluation Systems Test (Mini BEStest) [5] were assessed. Spearman’s rank correlation test was used for analysis. Results There were significant negative correlations between trunk position sense and trunk flexor, extensor, dominant and non-dominant lateral side muscle endurance (r=-0.61, p=0.001; r=-049, p=0.011; r=-0.048, p=0.014; r=-0,048, p=0.014, respectively). There were also high significant negative correlations between trunk position sense and Mini BEStest score (r=-0.73, p Conclusion It was found that there were moderate to high correlations between trunk position sense, trunk muscle endurance and balance. Therefore, addition of trunk position sense training to the rehabilitation programs might be effective in improving trunk muscle endurance and balance in women with FMS.
