Physical activity in its various forms are the most recommended prevention and treatment strategy for chronic low back pain (CLBP). Standing postural stability is a prerequisite for many types of physical activities. Systematic reviews have investigated the evidence for an association between CLBP and postural stability but results remain inconclusive.
Our primary objective was to compare postural stability between pain-free controls and subjects with CLBP with or without leg pain and single and multisite chronic musculoskeletal pain subjects. The secondary objectives were to evaluate the association between postural stability with CLBP intensity and duration, demographics, physical characteristics and validated health and pain-related patient-reported outcome measures (PROMs).
STUDY DESIGN/SETTING: Cross-sectional study in a private chiropractic clinic setting PATIENT SAMPLE: Subjects included 42 pain-free controls and 187 patients with chronic musculoskeletal pain divided into CLBP with or without leg pain and single and multisite pain groups.
Pain intensity was measured using the numerical pain rating scale, PROMs Central Sensitization Inventory, Tampa Scale of Kinesiophobia, The Depression Scale, EuroQol-5D, Roland-Morris Disability Questionnaire, and Pain and Sleep Questionnaire Three-Item Index disability. Group differences were measured using area and velocity of sway on the force plate.
Postural stability was assessed using a force plate on four 60-second bipedal quiet stance tests: eyes open on a stable surface, eyes closed on a stable surface, eyes open on an unstable foam surface, eyes closed on an unstable foam surface. Following the clinic visit, subjects completed an online web-based data entry detailing pain history, demographic data, physical characteristics, pain intensity via the numerical pain rating scale, and PROMS.
Postural sway parameters did not differ between pain-free controls and subjects with CLBP with or without leg pain and single and multisite chronic musculoskeletal pain subjects. Furthermore, severity and duration of CLBP pain in addition to central sensitization, kinesiophobia, depression, quality of life, disability, and effect of pain on sleep only had very weak associations with postural stability.
Chronic musculoskeletal pain appears not to influence bipedal postural stability.
各种形式的身体活动是预防和治疗慢性下腰痛（CLBP）的最推荐策略。站立姿势稳定性是许多身体活动的前提。系统评价已经研究了 CLBP 与姿势稳定性之间的关联证据，但结果仍不确定。
我们的主要目的是比较无疼痛对照组和有 CLBP 以及有或无腿部疼痛以及单部位和多部位慢性肌肉骨骼疼痛的受试者之间的姿势稳定性。次要目标是评估姿势稳定性与 CLBP 强度和持续时间、人口统计学、身体特征以及经过验证的健康和疼痛相关的患者报告结局测量（PROM）之间的关系。
研究设计/设置：私人脊骨疗法诊所的横断面研究
受试者包括 42 名无疼痛对照组和 187 名患有慢性肌肉骨骼疼痛的患者，分为有或无腿部疼痛以及单部位和多部位疼痛组。
疼痛强度使用数字疼痛评分量表测量，PROM 中心敏感化量表、坦帕运动恐惧量表、抑郁量表、EuroQol-5D、Roland-Morris 残疾问卷和疼痛和睡眠问卷三项指数残疾。使用力板上的摆动面积和速度来测量组间差异。
使用力板在四个 60 秒的双足静态站立测试中评估姿势稳定性：稳定表面睁眼、稳定表面闭眼、不稳定泡沫表面睁眼、不稳定泡沫表面闭眼。在诊所就诊后，受试者通过在线网络数据输入详细记录疼痛史、人口统计学数据、身体特征、数字疼痛评分量表的疼痛强度以及 PROM。
无疼痛对照组和有 CLBP 以及有或无腿部疼痛和单部位和多部位慢性肌肉骨骼疼痛的受试者之间的姿势摆动参数没有差异。此外，CLBP 疼痛的严重程度和持续时间以及中枢敏化、运动恐惧、抑郁、生活质量、残疾以及疼痛对睡眠的影响仅与姿势稳定性有非常弱的关联。
慢性肌肉骨骼疼痛似乎不会影响双足姿势稳定性。
