腰椎旁肌 (LPM) 对于慢性腰痛 (CLBP) 患者的脊柱稳定非常重要。然而，CLBP 患者 LPM 的电特性仍不清楚。电阻抗肌电图 (EIM) 是一种新颖的非侵入性技术，可对 LPM 的电特性进行简单的定量评估。本研究旨在应用 EIM 评估 CLBP 患者和健康对照 (HC) 患者之间 LPM 的电特性。 30 名参与者（15 名 CLBP 参与者；15 名健康对照）参加了该研究。 CLBP组的参与者被要求完成视觉模拟量表（VAS）、Oswestry残疾指数（ODI）和罗兰-莫里斯残疾问卷（RDQ）以评估日常生活中的疼痛强度和残疾。采用独立样本t检验分析两组的基本特征。在 5、50、100 和 200 kHz 电流频率下，测量了 LPM 每侧的电气特性。以年龄为协变量，通过单向方差分析（ANOVA）对电阻（R）、电抗（X）、相位角（PA）和Z值的EIM参数进行分析。应用 Spearman 等级相关系数分析探讨问卷与 EIM 参数之间的关系。 CLBP组双侧LPM的R、Z值显着大于HC组；在这四个测试的电流频率下，PA 下降，X 没有变化。在 5 kHz 时，右侧的 Z 和 R 在患者和 HC 之间没有显着差异。相关分析显示，在 50 kHz 时，ODI 和 RDQ 评分与双侧 LPM 的 R 呈负相关（分别为 r = 0.523、r = 0.581；p < 0.05）。 RDQ 分数与右侧 LPM 的 PA 呈正相关（r = 0.521，p < 0.05）。无论使用不同的频率，CLBP 参与者和健康个体的双侧 LPM 电特性都不同。 CLBP 患者 LPM 电特性的改变在一定程度上与日常生活中的残疾相关。
Lumbar paraspinal muscle (LPM) is important in spinal stabilization in patients with chronic low back pain (CLBP). However, the electrical properties of LPM in patients with CLBP remain unclear. Electrical impedance myography (EIM) is a novel and non-invasive technique that provides a simple quantitative evaluation of electrical properties of the LPM. This study aimed to apply EIM to assess the electrical properties of the LPM between patients with CLBP and healthy control (HC). Thirty participants (15 CLBP participants; 15 healthy controls) were enrolled in the study. Participants in the CLBP group were asked to complete the visual analog scale (VAS), Oswestry Disability Index (ODI), and Roland–Morris Disability Questionnaire (RDQ) to assess the pain intensity and disability in daily life. Independent sample t-tests were adopted to analyze the basic characteristics between the two groups. At 5, 50, 100, and 200 kHz current frequencies, the electrical properties were measured on each side of the LPM. The EIM parameters of resistance (R), reactance (X), phase angle (PA), and Z value were analyzed by one-way analysis of variance (ANOVA), with age as covariate. Spearman's rank correlation coefficient analysis was applied to explore the relationships between the questionnaires and the EIM parameters. The R and Z values of bilateral LPM in the CLBP group were significantly larger than those in the HC group; the PA decreased and the X did not change at these four tested current frequencies. At 5 kHz, Z and R on the right side were non-significantly different between patients and HCs. Correlation analysis showed that at 50 kHz, ODI and RDQ scores correlated negatively with the R of the bilateral LPM (r = 0.523, r = 0.581, respectively; p < 0.05). RDQ scores correlated positively with the PA of the right LPM (r = 0.521, p < 0.05). The electrical properties of the bilateral LPM differed between CLBP participants and healthy individuals, regardless of the different frequencies used. These altered electrical properties of the LPM in the patients with CLBP correlated to some extent with disability in daily life.
