Impaired Trunk Posture in Women With Fibromyalgia

Study Design. A cross-sectional study. Objectives. The main goal of the study was to analyze posture of Fibromyalgia syndrome (FMS) in women compared with healthy subjects to establish if posture assessment could be useful to characterize the syndrome. Secondarily, we explored the impact of sedentary behavior on trunk posture. Summary of Background Data. Pain has been associated with poor static postures, however there is little information on the effect of FMS, which is characterized by widespread pain, on trunk posture. Methods. One hundred eighteen women with FMS and 110 healthy counterparts participated in this study, in which trunk posture was assessed. The thoracic kyphosis, forward head position, and shoulder position (basal and maximum protraction) were measured. Further, maximum shoulder protraction and the ability to maintain the cervical and thoracic angle were assessed. To compare the differences in posture depending on the grouping, an independent Student t test was conducted. To analyze the differences between groups in the ability to maintain the position over a period of time and the differences in posture depending on more or less active lifestyles, two multivariate analysis of variance were performed. Results. The results showed a significantly larger thoracic kyphosis, baseline shoulder protraction and lower craniovertebral angle and maximum protraction in FMG compared with CG (P  Conclusion. FMS female population present an altered trunk posture and an inability to maintain trunk position. Since this does not appear to be influenced by a more or less active lifestyle, specific treatment programs are needed to manage this clinical condition. Conclusion. Level of Evidence: 2
