This study aims to discover the effects of keyboard usage and how different keyboard styles can influence these. Biometrics Ltd Goniometers are used to quantify wrist and elbow joint angle of each subject throughout the study. Participants follow strict instructions which involve using different styles of keyboards in different seating/resting positions. Goniometer data along with other measured parameters from each test situation is compared and results are discussed.

Biometrics Ltd EMG sensors and an Accelerometer are used in this study to determine Muscle Reflex Contraction Latency. Study participants included developing children and children suffering from a developmental coordination disorder, the study aims to quantify the differences in muscular response between these two groups. Results are presented and discussed.

This study explores the effect that developmental coordination disorder has on children specifically in regard to lower limb muscle reflexes and postural control. Biometrics EMG sensors are applied to the leg of each subject along with an Accelerometer to record trunk perturbation, both sensor types are connected to the DataLOG unit. The experimental protocol is completed for each subject and results are presented and discussed.

Biometrics Ltd surface EMG sensors are applied over the core muscles of subjects from two groups (individuals with and without an expert Kinesiology tape application); sensors are connected to the DataLOG unit which is subject worn via a belt around the waist. A variety of TRX exercises are performed and results are discussed to present a comparison between EMG RMS values from both subject groups (RMS data is calculated using the Biometrics DataLOG Analysis Software).

This study utilises data recorded from four Biometrics Ltd Goniometers placed bilaterally on the knee and ankle of study participants to quantify the joint angles of a turning movement. Goniometer data is presented along with other measured parameters to identify whether or not there is a pattern in patients post-stroke performing a turning movement and if there is a relationship between the turning direction and falls.

Biometrics Ltd EMG used to monitor activities of extensor digitorum communis (EDC) and flexor digitorium superficialis (FDS) during various hand activities while the Biometrics Ltd Goniometer simultaneously measured the wrist movement and number of repetitions.

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.
