: Cervical muscle strength, proposed as a modifiable risk factor in concussions, can be assessed using various methods. The purpose of this study was to compare the reliability and force outputs of 3 methods that use handheld dynamometry (HHD) for assessing cervical muscle strength.
: All 3 testing methods are reliable, and force outputs are significantly different between methods.
: Repeated-measures reliability.
: Level 5.
: The study used a convenience sample of 30 participants. HHD "make tests" for cervical extension, flexion, and right and left side bending were performed using lying push tests, sitting push tests, and sitting pull tests. A sole examiner performed all tests. Two testing sessions were conducted 1 week apart. Analysis included intraclass correlation coefficients (ICCs), repeated-measures analyses of variance (α = 0.05) with post hoc Bonferroni tests, and minimal detectable change (MDC) calculations.
: All testing methods were reliable; the lying push test had the greatest point estimate values (ICC, 0.89-0.95). Significant differences in force were found between the 3 testing methods. The MDC was most sensitive for the lying push method.
: Of the 3 cervical muscle testing methods investigated, the lying position with a push test had the largest ICC according to the point estimate and the most sensitive MDC. Force values between the 3 methods were significantly different, which suggests that consistent testing methods should be used.
: Results from this study support the clinical use of an HHD "make test" in a lying position for assessing cervical muscle strength. The test is reliable and more sensitive to change compared with tests in a seated position.
颈部肌肉力量被认为是脑震荡的一个可改变的危险因素，可以用各种方法进行评估。本研究的目的是比较 3 种使用手持测力计（HHD）评估颈部肌肉力量的方法的可靠性和力量输出。
所有 3 种测试方法均可靠，且方法之间的力量输出存在显著差异。
重复测量可靠性研究。
5 级。
本研究使用了便利样本 30 名参与者。使用仰卧推测试、坐姿推测试和坐姿拉测试进行 HHD 的颈椎伸展、屈曲以及右侧和左侧侧屈的“制作测试”。由一位单一的检查者进行所有测试。两次测试相隔 1 周进行。分析包括组内相关系数（ICC）、重复测量方差分析（α=0.05），以及事后 Bonferroni 检验和最小可检测变化（MDC）计算。
所有测试方法均可靠；仰卧推测试的点估计值（ICC，0.89-0.95）最大。3 种测试方法之间存在显著的力量差异。仰卧推法的 MDC 最敏感。
在所研究的 3 种颈椎肌肉测试方法中，推仰卧位的方法根据点估计具有最大的 ICC，且 MDC 最敏感。3 种方法之间的力量值存在显著差异，这表明应使用一致的测试方法。
本研究结果支持在仰卧位使用 HHD“制作测试”评估颈部肌肉力量的临床应用。与坐姿测试相比，该测试更可靠，对变化更敏感。
