In this study, the reliability of the longus colli muscle (LCM) size was assessed in a relaxed state by a real time ultrasonography (US) device in a group of healthy subjects and a group of patients with chronic neck pain. Fifteen healthy subjects (19-41 years old) and 10 patients with chronic neck pain (27-44 years old) were recruited for the purpose of this study. LCM size was measured at the level of thyroid cartilage. Two images were taken on the same day with an hour interval to assess the within day reliability and the third image was taken 1 week later to determine between days reliability. Cross sectional area (CSA), anterior posterior dimension (APD), and lateral dimension (LD) were measured each time. The shape ratio was calculated as LD/APD. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were computed for data analysis. The ICC of left and right CSA for within day and between days reliability in healthy subjects were (0.90, 0.93) and (0.85, 0.82), respectively. The ICC of left and right CSA for within day and between days reliability in patients with neck pain were (0.86, 0.82) and (0.76, 0.81), respectively. The results indicated that US could be used as a reliable tool to measure the LCM dimensions in healthy subjects and patients with chronic neck pain.
在本研究中，通过实时超声（US）设备在一组健康受试者和一组慢性颈痛患者中评估了颈长肌（LCM）在松弛状态下大小的可靠性。招募了15名健康受试者（19 - 41岁）和10名慢性颈痛患者（27 - 44岁）用于本研究。在甲状腺软骨水平测量LCM大小。在同一天间隔一小时拍摄两张图像以评估日内可靠性，在1周后拍摄第三张图像以确定日间可靠性。每次测量横截面积（CSA）、前后径（APD）和左右径（LD）。计算形状比为LD/APD。计算组内相关系数（ICC）和测量标准误差（SEM）用于数据分析。健康受试者左右CSA日内和日间可靠性的ICC分别为（0.90，0.93）和（0.85，0.82）。颈痛患者左右CSA日内和日间可靠性的ICC分别为（0.86，0.82）和（0.76，0.81）。结果表明，超声可作为测量健康受试者和慢性颈痛患者LCM尺寸的可靠工具。
