OBJECTIVE
Craniocervical (CC) muscles control posture of the CC area. Muscle imbalance at this area induces musculoskeletal disorders. The purpose of this study was to develop a device for measuring isometric force of CC flexor and extensor muscles and to evaluate its intra-rater reliability.
METHOD
Isometric force of CC flexor and extensor muscles was measured in 20 women by one examiner on two days with a custom-made device. The intra-class correlation coefficient (ICC), standard error of measurements (SEM), smallest detectable difference (SDD), and Pearson correlation coefficient were computed.
RESULTS
The results of this study revealed that this device had excellent reliability (ICC: 0.98, SEM: 2.29 N, SDD: 6.36 N, Pearson correlation coefficient: 0.97 for CC flexor muscles and ICC: 0.97, SEM: 2.13 N, SDD: 5.91 N, Pearson correlation coefficient: 0.94 for CC extensor muscles).
DISCUSSION
This new device can improve knowledge about the CC muscle and efficacy of treatments in patients with poor posture.
目的
颅颈（CC）肌肉控制着CC区域的姿势。该区域的肌肉失衡会引发肌肉骨骼疾病。本研究的目的是开发一种用于测量CC屈肌和伸肌等长肌力的装置，并评估其在同一评估者内的可靠性。
方法
由一名检查者使用定制装置，在两天内对20名女性的CC屈肌和伸肌等长肌力进行测量。计算组内相关系数（ICC）、测量标准误差（SEM）、最小可检测差异（SDD）和皮尔逊相关系数。
结果
本研究结果表明，该装置具有出色的可靠性（CC屈肌：ICC为0.98，SEM为2.29 N，SDD为6.36 N，皮尔逊相关系数为0.97；CC伸肌：ICC为0.97，SEM为2.13 N，SDD为5.91 N，皮尔逊相关系数为0.94）。
讨论
这种新装置可以增进对CC肌肉的了解以及对姿势不良患者的治疗效果。
