Biometrics Ltd flexible electrogoniometers were used to record the motion of both hips and knees in total hip replacement patients. Four flexible electrogoniometers are used to measure the flexion-extension angles of both hips and both knees. The electrogoniometer system has proved capable of quantifying the functional status of hip replacement patients simply and economically within the clinical environment.

An integrated study on the performance of bandages which related pressures generated by the bandages to mechanical laboratory tests has highlighted the influence of posture on the interface pressures generated by these devices. The continuous ambulatory pressure monitoring system consisted of three elements, the pressure sensing device, a Biometrics Ltd Goniometer to determine the position of the leg, and the Biometrics Ltd Datalogger for recording the output of the measuring devices. The Goniometer allowed the stand/sit/lie sequence to be identified relatively easily. The effect of posture was also seen in the long-term measurements.

Biometrics Ltd electrogoniometers and footswitches were used in this study to evaluate the effect of electrical stimulation of the anterior tibial muscles of children with hemiplegic cerebral palsy on the gait pattern and the range of active and passive lower extremity movement. dorsiflexion of the ankle. Foot switches were placed under the sole and heel of the foot and simultaneously recorded the pattern of contact of the foot with the floor so that the temporal parameters of the gait cycle could be analyzed. The use of electrogoniometers for gait analysis proved successful, and could provide therapists and physicians with a relatively cheap and versatile means of quantitatively monitoring gait pattern and the effects of therapy.

This study focuses on assessing the precision of available knee-moment angle evaluation methods as well as determining the knee-moment angle characteristics in children suffering from spastic cerebral palsy. A Biometrics Ltd Goniometer is used to verify knee angles recorded throughout this study, Goniometer data along with other measured parameters is displayed and discussed to confirm if there are any significant findings in results taken from typically developing children and children with spastic cerebral palsy as well as the measurement error involved.

Biometrics Ltd EMG sensors (connected to the DataLlNK unit) are used to record muscle activity throughout this study. Each participant is subjected to a simulated ankle sprain followed by either a wet-ice or cold-water treatment, a group of the subject population received no treatment for the experimental control. Muscle reaction data is presented and discussed to confirm which treatment option is best.
