未经证实:腰椎多裂肌(LMM)功能障碍被认为与慢性下腰痛(CLBP)患者的疼痛和/或残疾有关。虽然心理社会因素在疼痛/残疾中起主要作用,在分析LMM和CLBP之间的关联时,它们很少被认为是混杂因素.
UNASSIGNED:本研究旨在确定:(1)心理因素的差异,失眠,有和没有CLBP的人之间的LMM特征;(2)心理因素之间的关联,失眠,或CLBP患者的LMM特征和下腰痛(LBP)强度或LBP相关残疾;(3)考虑混杂因素后,CLBP患者的LMM特征是否与LBP症状相关。
未经评估:78名患有CLBP的志愿者和73名没有CLBP的志愿者提供了社会人口统计信息,填写了11分数字疼痛评分量表和罗兰-莫里斯残疾问卷(RMDQ)。他们完成了医院焦虑和抑郁量表(HADS),疼痛突变量表(PCS),恐惧回避信念问卷(FAB),和失眠严重程度指数量表(ISI)。从亮度模式超声图像中测量L4-S1水平的LMM的静息和收缩厚度。计算收缩过程中L4-S1水平下LMM的厚度变化百分比。通过剪切波弹性成像测量L4-S1处的静息LMM刚度。LMM之间的关联,通过单变量和多变量分析对社会心理或失眠参数和临床结局进行分析.
未经证实:患有CLBP的人表现出明显更高的LBP强度,RMDQ,HADS,FAB,PCS,和ISI评分高于无症状对照组(p<0.05)。前者在收缩期间在L4/L5处也具有显著较小的LMM厚度变化百分比。LBP强度与PCS总分呈正相关,PCS-无助,FAB-总计,FAB-工作,CLBP患者的ISI(p<0.05)。RMDQ得分与HADS总分呈正相关,有抑郁症,PCS-总计,FAB-总计,FAB-身体活动,PCS-无助,CLBP患者的ISI(p<0.05)。FAB工作和ISI得分共同解释了24%的LBP强度。仅FAB总分就可以解释CLBP患者中与LBP相关的残疾的34%的方差。
UNASSIGNED:更多的恐惧回避信念或失眠与CLBP患者的LBP强度和/或LBP相关残疾有关。尽管CLBP患者被认为具有异常的LMM形态测量/功能,考虑其他混杂因素后,LMM特征与LBP强度或LBP相关残疾无关.
UNASSIGNED: Lumbar multifidus muscle (LMM) dysfunction is thought to be related to pain and/or disability in people with chronic low back pain (CLBP). Although psychosocial factors play a major role in pain/disability, they are seldom considered as confounders in analyzing the association between LMM and CLBP.
UNASSIGNED: This study aimed to determine: (1) differences in psychological factors, insomnia, and LMM characteristics between people with and without CLBP; (2) associations between psychological factors, insomnia, or LMM characteristics and low back pain (LBP) intensity or LBP-related disability in people with CLBP; and (3) whether LMM characteristics are related to LBP symptoms in people with CLBP after considering confounders.
UNASSIGNED: Seventy-eight volunteers with CLBP and 73 without CLBP provided sociodemographic information, filled the 11-point numeric pain rating scale and Roland-Morris disability questionnaire (RMDQ). They completed the Hospital Anxiety and Depression Scale (HADS), Pain Catastrophizing Scale (PCS), Fear Avoidance Belief Questionnaire (FAB), and Insomnia Severity Index Scale (ISI). Resting and contracted thickness of LMM at L4-S1 levels were measured from brightness-mode ultrasound images. Percent thickness changes of LMM at L4-S1 levels during contraction were calculated. Resting LMM stiffness at L4-S1 was measured by shear wave elastography. Associations among LMM, psychosocial or insomnia parameters and clinical outcomes were analyzed by univariate and multivariate analyses.
UNASSIGNED: People with CLBP demonstrated significantly higher LBP-intensity, RMDQ, HADS, FAB, PCS, and ISI scores than asymptomatic controls (p < 0.05). The former also had significantly smaller percent thickness changes of LMM at L4/L5 during contraction. LBP-intensity was positively related to scores of PCS-total, PCS-helplessness, FAB-total, FAB-work, and ISI in people with CLBP (p < 0.05). RMDQ scores were positively associated with the scores of HADS-total, HADS-depression, PCS-total, FAB-total, FAB-physical activity, PCS-helplessness, and ISI in people with CLBP (p < 0.05). FAB-work and ISI scores together explained 24% of LBP-intensity. FAB-total scores alone explained 34% of variance of LBP-related disability in people with CLBP.
UNASSIGNED: More fear-avoidance belief or insomnia is related to greater LBP-intensity and/or LBP-related disability in people with CLBP. Although people with CLBP were thought to have aberrant LMM morphometry/function, no LMM characteristics were related to LBP-intensity or LBP-related disability after considering other confounders.
