This study aimed to investigate trunk position sense, postural stability, and spine posture in women with fibromyalgia syndrome (FMS). Fifteen (15) women with FMS and age- and gender-matched fifteen (15) healthy controls were included. Trunk position sense as indicated by trunk reposition errors (TRE) and spine posture (thoracic and lumbar curvature) was measured with a digital inclinometer. Postural stability [eyes open (EO) and eyes closed (EC) on bipedal stance (BS), EO on monopedal stance (MS), and limits of stability (LOS)] was assessed with a computerized stabilometer (Prokin, TecnoBody S.R.L., Dalmine, 24044 Bergamo, Italy). TRE (p = 0.002) and the angle of thoracic curvature (p = 0.009) were found higher in women with FMS compared to healthy controls; however, the angle of lumbar curvature was similar (p = 0.467). It was seen that women with FMS had higher anterior-posterior sway in EO-BS (p = 0.009) and EC-BS (p = 0.001), ellipse area in EC-BS (p = 0.015), EO-MS of the dominant side (p = 0.021), and EO-MS of the non-dominant side (p = 0.007), and medial-lateral sway in EO-MS of the dominant (DM) side (p = 0.004) and the non-dominant (NDM) side (p = 0.002). Ellipse area in EO-BS (p = 0.054), medial-lateral sway in EO-BS (p = 0.983) and EC-BS (p = 0.290), anterior-posterior sway in EO-MS of the DM (p = 0.059) and the NDM side (p = 0.065), and LOS did not differ between groups (p = 0.274). Women with FMS had poor trunk position sense and postural instability, and alterations in spine posture. Therefore, the training of trunk position sense, postural stability, and posture might be beneficial and, thus, should be considered while planning an optimal treatment.

纤维肌痛的躯干位置感，姿势稳定性和脊柱姿势。

这项研究旨在调查患有纤维肌痛综合征（FMS）的女性的躯干位置感，姿势稳定性和脊柱姿势。包括十五（15）名具有FMS且年龄和性别相匹配的女性十五（15）名健康对照者。用数字测斜仪测量躯干位置感（如躯干重定位误差（TRE）和脊柱姿势（胸廓和腰椎弯曲））。用计算机稳定仪（Prokin，TecnoBody SRL，Dalmine）评估姿势稳定性[双足姿势（BS）的睁眼（EO）和闭眼（EC），单脚姿势（MS）和EO（极限）] ，24044贝加莫，意大利）。与健康对照组相比，FMS妇女的TRE（p = 0.002）和胸曲率角度（p = 0.009）高。但是，腰部弯曲的角度相似（p = 0.467）。可以看出，患有FMS的女性在EO-BS（p = 0.009）和EC-BS（p = 0.001），EC-BS的椭圆面积（p = 0.015），优势型EO-MS的前后摆动较高。侧（p = 0.021）和非主导侧的EO-MS（p = 0.007），以及主导（DM）侧（p = 0.004）和非主导（ NDM）一侧（p = 0.002）。DM的EO-BS的椭圆面积（p = 0.054），EO-BS的内侧-外侧摇摆（p = 0.983）和EC-BS的椭圆面积（p = 0.290），DM的EO-MS的前-后摇摆（p = 0.059） ）和NDM一侧（p = 0.065），两组之间的LOS没有差异（p = 0.274）。患有FMS的女性的躯干位置感和姿势不稳以及脊柱姿势发生改变。因此，锻炼躯干的位置感，姿势稳定性和姿势可能是有益的，因此在计划最佳治疗方案时应予以考虑。
