In this study finger tapping ability was used as one of the parameters to quantify recovery following stroke. Biometrics Ltd finger Goniometers were used to measure the range of active flexion-extension movement of the MCP joint of the index finger.
The ability to perform 20 or more one-leg heel-rises is considered a 'normal' grade for muscle strength of the ankle plantar flexors, regardless of age and strength. Because muscle strength is closely related to age and sex, the 'normal' test criterion was re-evaluated in different groups categorized by age and sex. Biometrics Ltd electrogoniometers and instrumentation was used to measure the angle of ankle plantar flexion.

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.
