Data from: Balance deficiencies in women with fibromyalgia assessed using computerized dynamic posturography: a cross-sectional study in Spain

Objectives: Our aims were: 1) to compare the sensory organization of balance control and balance strategies between women with fibromialgia (FM) and healthy women; 2) to investigate which sensory component, i.e., vestibular, visual or somato-sensory, is the most affected in FM; and, 3), to determine the associations between the functional independence measure (FIM) and balance responses in FM. Design: Cross-sectional observational study. Setting: Urban regional hospital and university (Universidad Rey Juan Carlos, Madrid, Spain). Participants: Twenty women with FM and 20 matched healthy women. Primary/secondary outcome measures: The Sensory Organization Test (SOT) was used to determine postural sway and balance during six different conditions with subjects in a standing position. The Functional Independence Measure (FIM) was used to determine the level of functional independence in daily life activities. Between-group differences were analyzed with ANCOVA and the Spearman’s test was used for correlations. Results: Significant between-groups and between-conditions differences were found for all SOT conditions (all, P<0.001): women with FM showed lower scores being the vestibular score the most affected. Different correlations between SOT conditions and some specific daily life activities were observed in the FM group: bathing activity and balance condition 6 (rs=0.541; P<0.001), bed transfers activity and conditions 2 (rs=0.491; P<0.001) and 3 (rs=0.510; P<0.001), positioning strategy 6 and dressing the upper (rs=0.530; P<0.001) or lower (rs=0.562; P<0.001) body, and toileting (rs=0.521; P<0.001): the greater the loss of balance, the greater the interference on some daily life activities. Conclusions: Women with FM exhibited balance deficiencies and used different strategies for maintaining their balance in standing which was associated with a negative impact on functional independence.

研究目的：本研究旨在达成以下三项目标：1）对比纤维肌痛（fibromyalgia, FM）女性患者与健康女性的平衡控制感觉组织模式及平衡策略；2）探究纤维肌痛患者中受影响最为显著的感觉亚系统类型，即前庭、视觉或躯体感觉；3）明确纤维肌痛患者的功能独立性评定量表（Functional Independence Measure, FIM）评分与平衡反应之间的关联。
研究设计：横断面观察性研究。
研究地点：西班牙马德里胡安卡洛斯国王大学（Universidad Rey Juan Carlos）附属城市区域医院。
研究对象：20名纤维肌痛女性患者与20名匹配的健康女性对照。
主要/次要结局指标：采用感觉组织测试（Sensory Organization Test, SOT）评估受试者处于站立位时，6种不同工况下的姿势摆动与平衡能力；采用功能独立性评定量表（FIM）评估受试者日常生活活动的功能独立水平。组间差异采用协方差分析（ANCOVA）进行分析，相关性分析采用斯皮尔曼相关性检验。
研究结果：所有SOT工况均存在显著的组间与工况间差异（均P<0.001）：纤维肌痛女性患者的评分更低，其中前庭感觉评分受影响最为显著。纤维肌痛组中，SOT工况与部分特定日常生活活动存在相关性：沐浴活动与平衡工况6（rs=0.541；P<0.001）、床上转移活动与工况2（rs=0.491；P<0.001）及工况3（rs=0.510；P<0.001）、姿势策略6与上肢穿衣（rs=0.530；P<0.001）或下肢穿衣（rs=0.562；P<0.001）、如厕活动（rs=0.521；P<0.001）均存在相关性：平衡能力缺损程度越高，对部分日常生活活动的干扰就越强。
研究结论：纤维肌痛女性患者存在平衡功能缺损，且在站立位维持平衡时采用了与健康人群不同的平衡策略，该缺陷与患者的功能独立性受损存在负向关联。
