This study aims to determine if there is a significant difference in muscle activity between younger and older subjects and therefore if age is a contributing factor to knee joint functionality. Biometrics EMG sensors are used to record muscle activity of subjects and this data is presented, compared and discussed.

Biometrics Ltd Goniometers are fundamental in this study to ensure that a determined angle was reached and maintained throughout data collection. Data from other measured parameters is collected, compared and discussed; the Goniometers were used to control the knee joint angle to ensure a reliable and repeatable evaluation.

Biometrics Ltd Goniometers are used to support this investigation into commercially releasing a new gait rehabilitation device developed for Stroke patients. Subjects are instructed to walk using the gait rehabilitation device and a 'real' sloped surface, Ankle Goniometer data is recorded to confirm that the new device allows for healthy motion.

This study aims to analyse the physical characteristics of subjects carrying out a lifting activity in order to contribute to information regarding the mechanism and development of low back pain. Two Biometrics Ltd Goniometers were applied at specific points along the backbone of each subject for the duration of the experiment. The effects of lifting with and without load are discussed and verified using Goniometer and muscle activity data.

The subject population was evaluated at determined time intervals post TKA surgery. Biometrics Ltd Goniometers were used to measure hip ROM during active movement. Goniometer data is presented alongside other measured parameters to determine how significantly neglect-like symptoms contributed to pain.

Finger angle was measured using a Biometrics Ltd Goniometer throughout the duration of this finger-tapping study. Subjects were instructed to tap their finger (right hand side or left hand side) while a lower limb assistive robot perturbed the leg. Observations from the initial comparison are discussed to determine the effect on finger tapping when the leg is perturbed.

Biometrics Ltd EMG sensors were placed over the Vastus Lateralis muscle of each subject performing cycling sprints, raw EMG data is converted into RMS data for inclusion in a statistical analysis along with other measured parameters. Cycling sprints were performed under temperature controlled environments in order to identify the relationship between environmental temperature and neuromuscular efficiency.

This study aims to determine the requirements of a welding simulator in order to reduce the risks involved with training inexperienced individuals. Subjects, including welding professionals and beginners, are instructed to perform several welding-based tasks while a Biometrics Ltd Goniometer, attached to the wrist, and Biometrics Ltd EMG sensors recorded valuable movement data. The data collected is presented along with the outcome of the welding tasks to confirm the significant differences between the two subject groups.

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.
