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.
