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."

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.

This paper is about the development of the Biometrics Ltd electrogoniometer and its clinical applications: The device is very lightweight and the electrogoniometers can be worn beneath clothing, so the subject can move without inhibition. ...Tests using angular motion of the hip and knee joints...assessment of gait ...gait of amputees and patients cerebral palsy...assessing the postoperative performance of arthritic patients receiving the Souter-Strathclyde elbow prosthesis. It can be seen that electrogoniometers can provide information otherwise not available in a clinical environment.

Biometrics Ltd flexible electrogoniometers were used to record the motion of both hips and knees in total hip replacement patients. Four flexible electrogoniometers are used to measure the flexion-extension angles of both hips and both knees. The electrogoniometer system has proved capable of quantifying the functional status of hip replacement patients simply and economically within the clinical environment.

An integrated study on the performance of bandages which related pressures generated by the bandages to mechanical laboratory tests has highlighted the influence of posture on the interface pressures generated by these devices. The continuous ambulatory pressure monitoring system consisted of three elements, the pressure sensing device, a Biometrics Ltd Goniometer to determine the position of the leg, and the Biometrics Ltd Datalogger for recording the output of the measuring devices. The Goniometer allowed the stand/sit/lie sequence to be identified relatively easily. The effect of posture was also seen in the long-term measurements.
