Biometrics Ltd Goniometers (SG150's) are used to collect knee flexion/extension data for this study assessing the effect of injury on movement, all subjects suffer from an anterior cruciate ligament injury on one side. Goniometer data is presented alongside other measured parameters to give a statistical analysis comparing the injured with the non-injured side.

Biometrics Ltd EMG sensors and Goniometers were used for this extensive ergonomic study. EMG data from the forearm extensors and goniometry data from the wrist were collected simultaneously using the DataLOG unit. A large subject population was used involving workers from a wide range of industries in order to determine the effects on the wrist and forearm in different job roles.

The aim of this study was to determine the accuracy and feasibility of using a Biometrics Ltd electrogoniometer for measuring simple thumb movements and concluded that electrogoniometers have utility for studying thumb movements during mobile phone use and may be used to evaluate other thumb-based input devices.

Wrist positions and movements were recorded bilaterally, for both the flexion/extension and the deviation angles using Biometrics Ltd electrogoniometers and datalogger.

Twelve right-handed female dentists (six with and six without a history of definite neck/shoulder disorders, pair-wise matched for age) were studied when performing authentic dental work. Biometrics Ltd electrogoniometers were used to measure the wrist movements.

This study to gain objective and quantitative information concerning both static and dynamic aspects of workload on the wrist in field studies of fish processing industry workers with highly repetitive work and risk of CTD used a Biometrics Ltd biaxial flexible electrogoniometer and datalogger for recording of flexion and deviation angles of the wrist of the dominant hand. In order to evaluate forearm rotation a Biometrics Ltd Torsiometer, sensitive only to rotation and not influenced by flexion or deviation, was attached to the wrist.

Wrist angles of the dominant hand were measured for 32 randomly selected women during a total of 40 representative 20 minute work periods. A Biometrics Ltd twin axis electrogoniometer and a Datalogger were used for recording the flexion and extension, and the deviation angles of the wrist. The angular distributions, the angular velocity distributions, and the power spectra, were calculated to characterize the wrist movements during work.
