Abstract

Background

Low back pain (LBP) is one of the most common conditions in the United States. Dysfunctional patterns of the erector spinae (ES) and gluteus medius (GM) muscles often accompany episodes of LBP.

Objectives

To evaluate the intra-rater reliability of rehabilitative ultrasound imaging (RUSI) in obtaining thickness measurements of the ES and GM muscles at rest and during submaximal contraction.

Design

Single-group repeated-measures reliability study.

Methods

A volunteer sample of 30 adults with current LBP was examined. Thickness measurements of the ES and GM at rest and during contraction were obtained by using RUSI during a single session. Intraclass correlation coefficients (ICC) were used to estimate reliability. Reliability was further assessed by calculating standard error of measurement (SEM) and minimal detectable change (MDC).

Results

By using a mean of 3 measures, intra-rater reliability estimates ranged from 0.999 to 0.999 for ES, and 0.998 to 0.999 for GM. Reliability estimates for single thickness measures ranged from 0.997 to 0.998 for ES, and 0.995 to 0.997 for GM. Reliability estimates were lower for percent thickness change measures than the corresponding single thickness measures for all conditions.

Conclusions

RUSI thickness measurements of the ES and GM muscles in patients with LBP, when based on the mean of 3 measures, are highly reliable when taken by a single examiner in a single session.

腰背痛患者竖脊肌和臀中肌康复超声成像的评分者内部可靠性

背景腰背痛（LBP）是美国最常见的疾病之一。目标评估康复超声成像（RUSI）在获取静息和亚最大收缩时 ES 和 GM 肌肉厚度测量值的评分者内部可靠性。方法对 30 名患有腰背痛的成人志愿者样本进行了研究。在单次治疗中使用 RUSI 测量静息和收缩时 ES 和 GM 肌肉的厚度。类内相关系数（ICC）用于估计可靠性。通过计算测量标准误差 (SEM) 和最小可检测变化 (MDC) 进一步评估可靠性。结果通过使用 3 次测量的平均值，ES 的评分者内部可靠性估计值为 0.999 至 0.999，GM 为 0.998 至 0.999。ES 单项厚度测量的可靠性估计值为 0.997 至 0.998，GM 为 0.995 至 0.997。在所有情况下，厚度变化百分比测量值的可靠性估计值均低于相应的单一厚度测量值。结论RUSI 对腰椎间盘突出症患者的 ES 和 GM 肌肉进行的厚度测量以 3 项测量值的平均值为基础，由一名检查员在单次治疗中进行测量时，可靠性非常高。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
