Reliability and Validity of an Electronic Dynamometer for Measuring Grip Strength; D Allen, F Barnett; International Journal of Therapy and Rehabilitation 18(5)258-265 (May 2011); The purpose of this study was to establish the concurrent validity and test-retest reliability of the Biometrics electronic dynamometer, and compare it with the criterion standard hydraulic Jamar dynamometer for measurement of grip strength among healthy participants. Conclusions in the results discussion include: "The concurrent validity between the Biometrics and Jamar dynamometers was found to be excellent for both the right (0.986) and left hands (0.983),and indicates that both the Jamar and Biometrics dynamometers maesure the same construct of grip strength. Results also indicate that the Biometrics dynamometer is a valid tool for measuring grip strength." and "Electronic dynamometers also have increased sensitivity to applied force, which therefore enables electronic dynamometers, such as the Biometrics to record low grip strength that may not have registered on the Jamar." The Practical implications state: "This study has established that the Biometrics E-LINK evaluation system is a valid and reliable measurement tool to use by rehabilitation professionals."

The Reliability of One vs. Three Trials of Pain-free Grip Strength in Subjects with Rheumatoid Arthritis; D Kennedy, C Jerosch-Herold, M Hickson; Journal of Hand Therapy Oct-Dec 2010; 23:384-391; A Biometrics Ltd Dynamometer was used to measure the test-retest reliability of one vs. three trials. The Implications for Practice included: "The results of this study demonstrate levels of test-retest reliability (ICC ≥0.91) for the evaluation of one and the mean of three trials of pain-free grip strength tested using the Biometrics E-LINK evaluation system in participants with RA....A change in grip strength as small as 1.6 kg may be indicative of meaningful clinical change in RA patients; therefore, grip should be evaluated with an instrument with adequate sensitivity to detect this magnitude of change."
