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."

This investigation compared the reliability and interchangeable use of three currently available Goniometers - a universal Goniometer, a fluid Goniometer, and a Biometrics Ltd electrogoniometer. Three consecutive readings of the active range of movement of the right elbow joint were taken from each of 23 healthy female volunteers; three experienced observers each used each type of Goniometer on two occasions. Significant intertester differences were found to exist for both the universal and fluid Goniometers. However, no significant differences were found between any of the testers with respect to the electrogoniometer. It therefore appears reasonable to suggest that, with respect to reducing intertester differences, the electrogoniometer is preferable.
