Clinical Methods of Goniometry: a Comparative Study; J Goodwin, C Clark, J Deakes, D Burdon, C Lawrence; Disability and Rehabilitation 1992; Vol 14, No.1; pp 10-15 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.
