This study compared the Jamar and Rolyan hydraulic dynamometers to determine their concurrent validity with known weights as well as their inter-instrument reliability and concurrent validity for measuring grip strength in a clinical setting. Thirty females and 30 males were tested on these two grip strength measurement devices using a repeated measure design. Results showed that the Jamar and Rolyan dynamometers have acceptable concurrent validity with known weights (that is, correlation coefficients were r > or = 0.9994), excellent inter-instrument reliability (that is, intraclass correlation coefficients ranged from 0.90 to 0.97) and strong concurrent validity (that is, no significant differences between dynamometers' scores). Data indicate that Jamar and Rolyan dynamometers measure grip strength equivalently and can be used interchangeably. Thus, therapists using the Rolyan dynamometer are justified in using published normative data, which were collected with the Jamar dynamometer.
本研究对Jamar握力计和Rolyan液压握力计进行了比较，以确定它们与已知重量的同时效度，以及在临床环境中测量握力时的仪器间可靠性和同时效度。采用重复测量设计，对30名女性和30名男性在这两种握力测量设备上进行了测试。结果表明，Jamar握力计和Rolyan握力计与已知重量具有可接受的同时效度（即相关系数r≥0.9994），具有出色的仪器间可靠性（即组内相关系数范围为0.90至0.97）和较强的同时效度（即握力计得分之间无显著差异）。数据表明，Jamar握力计和Rolyan握力计在测量握力方面等效，可互换使用。因此，使用Rolyan握力计的治疗师有理由使用用Jamar握力计收集的已发表的标准数据。
