PURPOSE/AIM: Postural control, proprioception and lower extremity muscle strength are affected in individuals with low back pain (LBP). However, it is yet unknown whether these variables differentiate between acute, subacute and chronic stages of LBP. The aim was to investigate if there were any differences in postural control, proprioception, lower extremity muscle strength, pain intensity and disability between individuals in the different stages of LBP.
In this cross-sectional study, 124 individuals with LBP were grouped as acute LBP (ALBP) ( = 38), subacute LBP (SLBP) ( = 30) and chronic LBP (CLBP) ( = 56) groups. Postural control was assessed computerised technology. Lumbar proprioception, lower extremity muscle strength, pain intensity and disability were assessed using Joint Repositioning Error Test, hand-held dynamometer, Numeric Rating Scale and Oswestry Disability Index (ODI), respectively. Kruskal-Wallis Tests, ANCOVA and Mann-Whitney U-Test with Bonferroni correction were performed.
While there were no significant differences in terms of postural control, proprioception and pain intensity ( > 0.05), significant differences were found in terms of lower extremity muscle strength and ODI scores between groups when adjusted for age ( < 0.05). Individuals with CLBP demonstrated poorer lower extremity muscle strength than those with ALBP and SLBP, and higher disability than those with ALBP ( < 0.017).
Although postural control, proprioception and pain intensity were similar between individuals with acute, subacute and chronic LBP, muscle strength and disability seem to worsen stepwise as the pain becomes chronic. Muscle strength and disability should be taken into account while evaluating and/or managing individuals with acute and subacute stages of LBP.
目的/目的：腰痛（LBP）患者的姿势控制、本体感觉和下肢肌肉力量受到影响。然而，目前尚不清楚这些变量是否可以区分 LBP 的急性、亚急性和慢性阶段。本研究旨在探讨不同阶段 LBP 患者的姿势控制、本体感觉、下肢肌肉力量、疼痛强度和残疾是否存在差异。
在这项横断面研究中，124 名 LBP 患者被分为急性 LBP（ALBP）（n=38）、亚急性 LBP（SLBP）（n=30）和慢性 LBP（CLBP）（n=56）组。姿势控制使用计算机技术评估。腰椎本体感觉、下肢肌肉力量、疼痛强度和残疾分别使用关节重定位误差测试、手持测力计、数字评分量表和 Oswestry 残疾指数（ODI）评估。进行 Kruskal-Wallis 检验、协方差分析和 Mann-Whitney U 检验，并用 Bonferroni 校正。
虽然在姿势控制、本体感觉和疼痛强度方面没有显著差异（>0.05），但在调整年龄后，各组之间下肢肌肉力量和 ODI 评分存在显著差异（<0.05）。CLBP 患者的下肢肌肉力量比 ALBP 和 SLBP 患者差，残疾程度比 ALBP 患者高（<0.017）。
尽管急性、亚急性和慢性 LBP 患者的姿势控制、本体感觉和疼痛强度相似，但随着疼痛变为慢性，肌肉力量和残疾似乎会逐渐恶化。在评估和/或管理急性和亚急性 LBP 患者时，应考虑肌肉力量和残疾。
