Walking up and down stairs is a common and important activity of daily living. Women with fibromyalgia often show a reduced ability to perform this task.The objective of this study was to evaluate the test-retest reliability of stair negotiation tasks and to assess the impact of fibromyalgia symptoms on the ability to negotiate stairs.Forty-two women with fibromyalgia participated in this descriptive correlational study. The relevance of the stair negotiation (both walking up and down) was evaluated by assessing its association with the revised version of the fibromyalgia impact questionnaire (FIQ-R) and other health-related variables. Test-retest reliability was also analyzed. The main outcome measures were time spent walking up and down stairs and impact of fibromyalgia, quality of life, number of falls, weight, and lower limb strength and endurance.The intraclass correlation coefficient (ICC) for stair descent was 0.929 whereas that for ascent was 0.972. The score in these tests correlated significantly with the total score for the FIQ-R and the score for many of dimensions and symptoms: that is, physical function, overall impact of fibromyalgia, pain, energy, stiffness, restorative sleep, tenderness, self-perceived balance problems, and sensitivity.Given the importance of the stair negotiation as activity of daily living and the high reliability, both stair ascent and descent tasks may be useful as outcome measures in studies on patients with fibromyalgia.
上下楼梯是日常生活中一项常见且重要的活动。纤维肌痛女性患者通常在执行这项任务时能力有所下降。本研究的目的是评估上下楼梯任务的重测信度，并评估纤维肌痛症状对上下楼梯能力的影响。42名纤维肌痛女性参与了这项描述性相关性研究。通过评估上下楼梯（上下行）与纤维肌痛影响问卷修订版（FIQ-R）及其他健康相关变量的关联，来评价其相关性。同时也分析了重测信度。主要结局指标为上下楼梯所花费的时间以及纤维肌痛的影响、生活质量、跌倒次数、体重、下肢力量和耐力。下楼梯的组内相关系数（ICC）为0.929，而上楼梯的为0.972。这些测试中的得分与FIQ-R总分以及许多维度和症状的得分显著相关，即身体功能、纤维肌痛的总体影响、疼痛、精力、僵硬、恢复性睡眠、压痛、自我感知的平衡问题和敏感性。鉴于上下楼梯作为日常生活活动的重要性以及高信度，上楼梯和下楼梯任务均可作为纤维肌痛患者研究中的结局指标。
