Neck pain ranks among the most prevalent musculoskeletal conditions and is commonly accompanied by altered physical function. With 10.8% of sports-related injuries affecting the head and neck, evaluating neck strength is vital for detecting muscle weakness and monitoring rehabilitation progress. The purpose of this study was to determine the intrasession and intersession reliability of a strain gauge for measuring neck retraction strength in healthy adult men. Ten male participants (age, 22.7 [2.6] y; body mass, 90.8 [13.3] kg; height, 184.2 [7.1] cm) completed a neck retraction isometric test across 3 testing occasions separated by 7 days. Contraction duration, peak and mean force, impulse, and peak rate of force development were quantified within and between sessions. Contraction duration, peak force, and impulse demonstrated moderate to excellent intra- (intraclass correlation coefficient [ICC] [3,1] = .72-.98, coefficient of variation [CV] = 2.7%-2.1%) and intersession reliability (ICC [3,k] = .66-.89, CV = 4.8%-7.1%); however, only acceptable intrasession reliability was found for peak rate of force development and mean force (ICC = .71-.99, CV = 3.4%-22.7%). It appears that a portable fixed strain gauge can be used to reliably measure neck retraction strength in a healthy male population.
颈部疼痛是最常见的肌肉骨骼疾病之一，通常伴有身体功能改变。在与运动相关的损伤中，有10.8%影响头部和颈部，因此评估颈部力量对于检测肌肉无力和监测康复进展至关重要。本研究的目的是确定一种应变仪在测量健康成年男性颈部后缩力量时的组内和组间可靠性。10名男性参与者（年龄22.7[2.6]岁；体重90.8[13.3]千克；身高184.2[7.1]厘米）在相隔7天的3个测试场合完成了颈部后缩等长测试。对收缩持续时间、峰值和平均力量、冲量以及力量发展的峰值速率在组内和组间进行了量化。收缩持续时间、峰值力量和冲量显示出中等至极好的组内可靠性（组内相关系数[ICC][3,1]=0.72 - 0.98，变异系数[CV]=2.7% - 2.1%）和组间可靠性（ICC[3,k]=0.66 - 0.89，CV = 4.8% - 7.1%）；然而，仅发现力量发展的峰值速率和平均力量具有可接受的组内可靠性（ICC = 0.71 - 0.99，CV = 3.4% - 22.7%）。看来便携式固定应变仪可用于可靠地测量健康男性群体的颈部后缩力量。
