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.

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.

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.

A combination of Biometrics sensors including Goniometers and EMG probes were used along with a force transducer to evaluate range of motion muscle activity and force simultaneously during exercise. With this data, clinicians are capable of studying the development of spasticity and wrist contractures over time in addition to confirming the relationship between spasticity, function and contracture development.

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."
