Objective. To investigate balance functions in older women and evaluate the association of the fear-avoidance beliefs model (FABM) factors with balance and mobility performance. Participants. Fifteen older women with CLBP was compared with age-matched pain-free controls (n = 15). Main Outcome Measures. Pain intensity, falls-related self-efficacy and intrinsic constructs in the FABM were evaluated. Postural steadiness (centre of pressure (COP)) and mobility functions were assessed. Linear relationships of FABM variables with COP and mobility score were estimated. Results. CLBP showed lower mobility score compared to controls. CLBP presented lower falls-related self-efficacy and it was associated with reduced mobility scores. FABM variables and falls-related self-efficacy were correlated with postural steadiness. Physical activity was reduced in CLBP, but no between-group difference was evident for knee extensor strength. No systematic linkages were observed between FABM variables with mobility score or postural steadiness. Conclusions. Back pain status affects balance and mobility functions in older women. Falls-related self-efficacy is lower in CLBP and is associated with reduced mobility. Disuse syndrome in CLBP elderly is partly supported by the results of this preliminary study.
目的。探讨老年女性的平衡功能，并评估恐惧-回避信念模型（FABM）因素与平衡及运动能力表现之间的关联。参与者。将15名患有慢性下腰痛（CLBP）的老年女性与年龄匹配的无疼痛对照组（n = 15）进行比较。主要观察指标。评估疼痛强度、与跌倒相关的自我效能感以及FABM中的内在结构。评估姿势稳定性（压力中心（COP））和运动功能。估计FABM变量与COP和运动得分之间的线性关系。结果。与对照组相比，CLBP患者的运动得分较低。CLBP患者表现出较低的与跌倒相关的自我效能感，且这与运动得分降低有关。FABM变量和与跌倒相关的自我效能感与姿势稳定性相关。CLBP患者的身体活动减少，但两组之间的膝关节伸肌力量无明显差异。未观察到FABM变量与运动得分或姿势稳定性之间存在系统性联系。结论。背痛状况会影响老年女性的平衡和运动功能。CLBP患者中与跌倒相关的自我效能感较低，且与运动能力下降有关。这项初步研究的结果部分支持了CLBP老年患者的废用综合征。
