To investigate the intrasession (test) and intersession (retest) reliability of rehabilitative ultrasound imaging (RUSI) in measuring the thickness of rectus capitis posterior major (RCPM) and oblique capitis superior (OCS) in patients with chronic non-specific neck pain (CNNP).
Thirty-three CNNP patients (age 35 12.82 years, 24 women and 9 men) participated in the study. One examiner measured the thickness of the right and left RCPM and OCS in their resting position. For intrasession reliability, two measurements were conducted with an interval of 15 min. As for the intersession reliability, measurements were repeated with an interval of 3 to 4 days after the first session. Intraclass correlation coefficients (ICC), standard error of measurement (SEM), minimal detectable change (MDC), coefficient of variation (CV), and Bland-Altman plots were used for data analysis.
The ICC results for intrasession and intersession reliability ranged from 0.89 to 0.95 and 0.84 to 0.91, respectively. The SEM ranged from 0.35 to 0.57, while the MDC ranged from 0.97 to 1.58. The Bland-Altman plots demonstrated good agreement and no bias.
The current study found RUSI to be a reliable instrument for measuring the thickness of RCPM and OCS in CNNP patients.
探讨康复超声成像（RUSI）在测量慢性非特异性颈部疼痛（CNNP）患者头后大直肌（RCPM）和头上斜肌（OCS）厚度时的组内（测试）和组间（重测）可靠性。
33例CNNP患者（年龄35±12.82岁，24名女性和9名男性）参与了本研究。一名检查者在静息位测量左右侧RCPM和OCS的厚度。对于组内可靠性，间隔15分钟进行两次测量。至于组间可靠性，在第一次测量后间隔3至4天重复测量。采用组内相关系数（ICC）、测量标准误差（SEM）、最小可检测变化（MDC）、变异系数（CV）和Bland-Altman图进行数据分析。
组内和组间可靠性的ICC结果分别为0.89至0.95和0.84至0.91。SEM范围为0.35至0.57，而MDC范围为0.97至1.58。Bland-Altman图显示一致性良好且无偏差。
本研究发现RUSI是测量CNNP患者RCPM和OCS厚度的可靠工具。
