To evaluate Ultrasound Imaging (USI) reliability for measurement of lumbar multifidus (LMF) muscle thickness and cross sectional area (CSA) at rest and during contraction in patients with unilateral lumbar disc herniation.
Laboratory.
Reliability Study.
Thirty patients, aged 25-50 years (37.55 ± 9.55), with unilateral L4-L5 lumbar disc herniation participated in this study.
Thickness and CSA of LMF were measured using B-mode ultrasound by two raters in prone position.
Same day and multiple day inter-rater and same day intra-rater reliability showed good to excellent reliability (intraclass correlation coefficients ranged from 0.70 to 0.91). Also standard error of measurement and minimal detectable change for USI reliabilities ranged from 0.06 to 0.57 and 0.16 to 1.31, respectively.
Reliability of USI for measurements of LMF muscle thickness and CSA was high, and consistent with previous studies conducted on reliability of USI to measure LMF dimensions in other populations.
评估超声成像（USI）在测量单侧腰椎间盘突出症患者静息和收缩时腰多裂肌（LMF）厚度及横截面积（CSA）方面的可靠性。
实验室。
可靠性研究。
30例年龄在25 - 50岁（37.55 ± 9.55）的单侧L4 - L5腰椎间盘突出症患者参与本研究。
两名评估者在俯卧位使用B型超声测量LMF的厚度和CSA。
同一天及多天的评估者间和同一天评估者内的可靠性显示出良好至优秀的可靠性（组内相关系数范围为0.70至0.91）。此外，USI可靠性的测量标准误差和最小可检测变化分别为0.06至0.57和0.16至1.31。
USI测量LMF肌肉厚度和CSA的可靠性较高，与先前在其他人群中进行的关于USI测量LMF尺寸可靠性的研究结果一致。
