This study aimed to determine the interrater and intrarater reliability of EasyForce dynamometer for assessing shoulder, knee, and hip muscle strength in healthy young adults. Shoulder, knee, and hip maximal isometric strength were measured using the EasyForce in healthy adults (11 women and 12 men). Three repetitions of shoulder internal rotation, abduction, knee flexion, extension, and hip abduction and adduction were performed. The tests were performed by three raters on the same day. The results showed good to high inter- and intrarater reliability (intraclass correlation coefficient range: 0.63-0.91). Moreover, the absolute reliability of the EasyForce was slightly higher than acceptable for all tests (CV > 10%) except for hip abduction on the right leg (CV = 7.2%). The EasyForce dynamometer can be considered a reliable tool for assessing shoulder internal rotation and abduction, knee extension and flexion, as well as hip abduction and adduction strength. The EasyForce dynamometer showed no differences between the raters' measurements, which could be of great importance for professionals who want to perform the tests regardless of their strength on the values.
本研究旨在确定EasyForce测力计在评估健康年轻成年人肩部、膝部和髋部肌肉力量时的评分者间信度和评分者内信度。在健康成年人（11名女性和12名男性）中使用EasyForce测量肩部、膝部和髋部的最大等长肌力。进行了三次肩部内旋、外展、膝部屈曲、伸展以及髋部外展和内收动作。测试由三名评分者在同一天进行。结果显示评分者间和评分者内信度良好至高（组内相关系数范围：0.63 - 0.91）。此外，除右腿髋部外展（CV = 7.2%）外，EasyForce在所有测试中的绝对信度略高于可接受水平（CV > 10%）。EasyForce测力计可被视为评估肩部内旋和外展、膝部伸展和屈曲以及髋部外展和内收力量的可靠工具。EasyForce测力计在评分者测量结果之间未显示差异，这对于想要进行测试而不论其力量值的专业人员可能非常重要。
