This study utilises Biometrics Ltd EMG sensors for gait analysis with biofeedback. Muscle activity is used to trigger an audible and vibrational alarm to both reward and help correct the subject under test conditions. Results are discussed and conclude that this setup could positively impact rehabilitation practice if used regularly in impaired populations.

Biometrics Ltd Goniometers were placed on the knees of study participants, this study aimed to collect knee extension data for a target population over a 6-10 hour period. The Biometrics Ltd DataLOG unit was used to allow for complete data acquisition (save to card mode) while the subjects carried out a typical 'work' day. Data was analysed post collection to quantify knee range of motion and knee extension changes when participating in different activities.

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.
