Reliability and Validity of an Electronic Dynamometer for Measuring Grip Strength
D Allen, F Barnett; International Journal of Therapy and Rehabilitation 18(5)258-265 (May 2011)
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."

Spasticity and contractures at the wrist after stroke: time course of development and their association with functional recovery of the upper limb
S Malhotra, AD Pandyan, S Rosewilliam, C Roffe, H Hermens; Clinical Rehabilitation 2011; 25: 184-191
Biometrics Ltd equipment is used to identify a relationship between upper limb functional recovery and the development of spasticity in stroke patients over a quantified time. 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.

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.
