背景：鉴于现有的手持式测功器种类繁多，而且它们的手柄形状不同，因此需要进行可靠性研究。目的：比较三种不同手持式测力仪的准确性和可靠性，分析手柄对握力的影响。方法：使用Jamar(R)测力仪、Takei(R)测力仪和改装手柄的肌电系统手动传感器进行测试。纳入18名健康志愿者，年龄20.0+/-1.3岁，无四肢肌肉骨骼疾病或创伤病史。数据的正态分布采用Shapiro-Wilk检验。为了验证测功器之间可能存在的差异，进行了重复测量的方差分析，然后进行了Tukey后检验。测量之间的可靠性使用组内相关系数(ICC)进行评估，一致性使用Bland和Altman曲线图进行检验。使用线性回归对测功机的校准过程进行了评估。结果：在女性组中，Jamar(R)和Takei(R)测力计之间的差异有统计学意义(女性P
Background: Given the variety of available hand-held dynamometers and their different handle shapes, reliability studies are needed. Objectives: To compare the accuracy and reliability between three different hand-held dynamometers and analyze the influence of their handles on grip strength. Methods: The tests were performed with the Jamar (R) dynamometer, the Takei (R) dynamometer and the EMG System Manual Transducer with modified handle. Eighteen healthy volunteers aged 20.0 +/- 1.3 years without history of musculoskeletal disorders or trauma in the evaluated limbs were included. Data normality was tested using the Shapiro-Wilk test. To verify possible differences between the dynamometers, repeated measures ANOVA was administered, followed by Tukey post-hoc tests. Reliability between measurements was evaluated using intraclass correlation coefficient (ICC) and agreement was tested using Bland and Altman plots. The dynamometers calibration process was evaluated using linear regressions. Results: We observed statistically significant differences on the female group between the Jamar (R) and the Takei (R) dynamometers (females p
