Repeated measures of grip strength obtained bilaterally with a Jamar and a MicroFET 4 dynamometer were compared. Measurements obtained with the MicroFET 4 tended to be slightly (2.2-3.1 lb.) higher but were highly correlated (r > or = .96) with those obtained with the Jamar. Parallel reliability for the two devices was excellent (intraclass correlation coefficient > or = .96). Although clinicians should be cautious about using the devices interchangeably, the MicroFET 4 appears to be a legitimate alternative to the Jamar dynamometer.
对使用Jamar和MicroFET 4握力计双侧重复测量获得的握力进行了比较。使用MicroFET 4获得的测量值往往略高（2.2 - 3.1磅），但与使用Jamar获得的测量值高度相关（r≥0.96）。两种设备的平行可靠性极佳（组内相关系数≥0.96）。尽管临床医生在互换使用这些设备时应谨慎，但MicroFET 4似乎是Jamar握力计的合理替代产品。
