Clinical Measurement.
Grip strength has been administered for many years with a wide variety of instruments and for very different purposes.
To examine the reliability and validity of a new grip measurement device, the multiaxis profile (MAP) dynamometer, compared with the Baseline dynamometer (Fabrication Enterprises Inc., White Plains, NY) and vigorimeter.
Twenty-eight participants (<30 yr, n=14; and >65 yr, n=14) completed grip strength testing using all three devices. Measurements were obtained at baseline and one to two weeks later.
Intraclass correlation coefficients (ICCs) for the MAP ranged from 0.94 to 0.99. The other two devices had ICCs of 0.95-0.98. Correlations among the MAP dynamometer, the Baseline dynamometer, and the vigorimeter were 0.78-0.90. The results indicate high concurrent validity among all the three devices and that all devices are reliable instruments to measure the grip strength of both younger and older adults.
In addition to measuring grip strength, the MAP dynamometer measures other grip-related information, such as grip force vectors, rate of force buildup, and force variability. This additional grip information may improve our understanding of hand function and changes because of aging.

临床测量。
多年来，人们使用各种仪器针对非常不同的目的进行握力测试。
研究一种新的握力测量设备——多轴轮廓（MAP）测力计与基线测力计（纽约白原市 Fabrication Enterprises Inc.）和握力计的可靠性和有效性。
28 名参与者（<30 岁，n=14；>65 岁，n=14）使用所有三种设备完成握力测试。在基线和一到两周后进行测量。
MAP 的组内相关系数（ICC）范围为 0.94 至 0.99。其他两种设备的 ICC 为 0.95-0.98。MAP 测力计、基线测力计和握力计之间的相关性为 0.78-0.90。结果表明，所有三种设备均具有高度的同时有效性，并且所有设备都是可靠的仪器，可测量年轻和老年成年人的握力。
除了测量握力外，MAP 测力计还可测量其他与握力相关的信息，如握力矢量、力量建立率和力量可变性。这些额外的握力信息可能会增进我们对手部功能及其因老化而发生变化的理解。
