There is no single, universally accepted method of measuring isometric neck strength to inform exercise prescription and injury risk prediction. This study aimed to establish the inter- and intra-rater reliability of a commercially available fixed frame dynamometer in measuring peak isometric neck strength. A convenience sample of male (n = 16) and female (n = 20) university students performed maximal isometric contractions for flexion (Flex), extension (Ext), left- (LSF) and right-side flexion (RSF) in a quadruped position over three sessions. The intra-rater reliability results were good-to-excellent for both males (ICC = 0.83−0.90) and females (ICC = 0.86−0.94) and acceptable (CV < 15%) across all directions for both males and females. The inter-rater reliability results were excellent (ICC = 0.96−0.97) and acceptable (CV < 11.1%) across all directions. Findings demonstrated a significant effect for sex (p ≤ 0.05): males were stronger in all four directions, and a significant effect for direction (p ≤ 0.05): Ext tested stronger (193 N) than Flex (176 N), LSF (130 N) and RSF (125 N). The findings show that the VALD fixed frame dynamometer can reliably assess isometric neck strength and can provides reference values for healthy males and females.
目前尚无一种单一的、被普遍接受的测量等长颈部力量的方法来指导运动处方和损伤风险预测。本研究旨在确定一种市售固定框架测力计在测量峰值等长颈部力量时的评分者间和评分者内信度。选取了方便样本，包括16名男性和20名女性大学生，在三个测试环节中以四足姿势进行屈曲（Flex）、伸展（Ext）、左侧屈曲（LSF）和右侧屈曲（RSF）的最大等长收缩。评分者内信度结果显示，男性（ICC = 0.83−0.90）和女性（ICC = 0.86−0.94）的结果均为良好至优秀，且男性和女性在所有方向上的结果均可接受（CV < 15%）。评分者间信度结果在所有方向上均为优秀（ICC = 0.96−0.97）且可接受（CV < 11.1%）。研究结果表明性别具有显著影响（p ≤ 0.05）：男性在所有四个方向上更强；方向也具有显著影响（p ≤ 0.05）：伸展测试结果（193 N）强于屈曲（176 N）、左侧屈曲（130 N）和右侧屈曲（125 N）。研究结果表明，VALD固定框架测力计能够可靠地评估等长颈部力量，并可为健康男性和女性提供参考值。
