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 measure 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."

In this study, blind resistance to passive movement measurements are taken using the Biometrics Ltd Goniometer along with a force transducer; data is then graded using the Ashworth Scale and Modified Ashworth Scale, all subjects are stroke patient volunteers. An investigation comparing the non-impaired arm with the impaired arm is presented as a sub analysis. Results are discussed following a statistical analysis to confirm the validity of the Ashworth scale with respect to biomechanical data.

Biometrics Ltd Goniometers are used simultaneously with a force transducer to verify resistance to passive motion. In order to quantify spasticity, blind data from the resistance to passive motion test is used together with the Modified Ashworth Scale to identify the 'catch' phenomenon. Findings regarding the relationship between the Modified Ashworth Scale and patient resistance to passive motion are presented. A statistical analysis is documented comparing the impaired arm with the non-impaired arm of participants in this study.

To determine the position of the wrist that results in the lowest carpal tunnel pressure, twenty control subjects and four patients who had carpal tunnel syndrome were evaluated with use of a new, dynamic method that continuously measures carpal tunnel pressure throughout the range of motion of the wrist. A Biometrics Ltd two-axis electrogoniometer was used to measure continuously the flexion or extension angle as well as the radial or ulnar deviation of the wrist.

Wrist angles of the dominant hand were measured for 32 randomly selected women during a total of 40 representative 20 minute work periods. A Biometrics Ltd twin axis electrogoniometer and a Datalogger were used for recording the flexion and extension, and the deviation angles of the wrist. The angular distributions, the angular velocity distributions, and the power spectra, were calculated to characterize the wrist movements during work.

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.

This paper shows the reliability and validity of Biometrics Ltd biaxial electrogoniometric analysis in the quantification of wrist circumduction. The reliability tests demonstrated sufficient accuracy of the device. Also, validity of the measurement was recognized because the tests simulating wrist circumduction and cineradiography revealed that it could accurately detect the angle between the long axis of the forearm and the third metacarpal bone.
