Our objective was to compare grip strength measurement in two body positions (sitting and standing) with the K-Force® Grip dynamometer and the Jamar® Plus Digital hand dynamometer, and to conduct a test-retest study of the K-Force Grip device. The study was conducted on 50 healthy young adults aged 18-25 years. Maximal grip strength was tested in sitting and standing positions with both devices. After 2 days, a re-test was conducted with the K-Force Grip. The correlation coefficient was high for grip strength measurements in sitting and standing positions with the K-Force Grip and Jamar Plus dynamometers (r > 0.9 for all). K-Force Grip values were similar in sitting and standing positions (p > 0.05). Despite this similarity, K-Force Grip measured significantly lower values than Jamar Plus (p < 0.05). Thus, the K-Force Grip device can be used as an alternative to the Jamar Plus dynamometer, regarded as the gold standard in evaluating grip strength. We believe that the same devices should be used in clinical studies, research, and patient follow-up.
我们的目的是比较两种体位（坐姿和站姿）下使用 K-Force®握力计和 Jamar®Plus 数字握力计测量握力的情况，并对 K-Force 握力计进行测试-再测试研究。该研究纳入了 50 名年龄在 18-25 岁的健康年轻成年人。使用两种设备分别测试坐姿和站姿时的最大握力。2 天后，使用 K-Force 握力计进行了再测试。K-Force 握力计在坐姿和站姿时与 Jamar Plus 测力计的测量值之间的相关系数很高（r>0.9，所有位置均如此）。K-Force 握力计在坐姿和站姿时的数值相似（p>0.05）。尽管如此，K-Force 握力计的测量值明显低于 Jamar Plus（p<0.05）。因此，K-Force 握力计可以替代被视为评估握力的金标准的 Jamar Plus 测力计。我们认为，在临床研究、研究和患者随访中，应使用相同的设备。
