Abstract/OtherAbstract:
STUDY DESIGN: Clinical Measurement.
INTRODUCTION: Grip strength has been administered for many years with a wide variety of instruments and for very different purposes.
PURPOSE OF THE STUDY: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
