To determine, with respect to measurement of maximal isometric torque (MIT) using a specific hand-held dynamometer (HHD) protocol, (1) protocol feasibility over a wide age range, (2) intra- and interrater reliability, (3) standard error of measurement, and (4) concurrent validity.
The MIT of selected upper and lower limb muscle groups was assessed (n = 74; age = 4-17.5 years) using a standardized, HHD protocol. Testing was repeated in 20 adolescents (n = 10 for each muscle group), who were also assessed with a Cybex dynamometer.
The protocol was feasible for all participants. Mean intra- and interrater reliability [intraclass correlation coefficient (ICC)] varied from 0.75 to 0.98, except for ankle dorsiflexor interrater reliability (mean ICC = 0.67). The standard error of measurement varied from 0.5 to 4.9 Nm and was highest for hip extensors. Mean concurrent validity (ICC) varied from 0.78 to 0.93, except for ankle plantar flexors (mean ICC = 0.48).
Our HHD protocol was feasible over a wide age range and most MIT values were valid and reliable.
关于使用特定手持式测力计（HHD）方案测量最大等长扭矩（MIT），确定（1）该方案在较宽年龄范围内的可行性，（2）评估者内和评估者间的可靠性，（3）测量标准误差，以及（4）同时效度。
使用标准化的HHD方案评估选定的上肢和下肢肌肉群的MIT（n = 74；年龄 = 4至17.5岁）。对20名青少年进行重复测试（每个肌肉群n = 10），这些青少年还使用Cybex测力计进行了评估。
该方案对所有参与者均可行。评估者内和评估者间的平均可靠性[组内相关系数（ICC）]在0.75至0.98之间变化，但踝关节背屈肌评估者间可靠性除外（平均ICC = 0.67）。测量标准误差在0.5至4.9 Nm之间变化，髋部伸肌的测量标准误差最高。平均同时效度（ICC）在0.78至0.93之间变化，但踝关节跖屈肌除外（平均ICC = 0.48）。
我们的HHD方案在较宽年龄范围内可行，且大多数MIT值有效且可靠。
