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.

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.

Participants of this study had all suffered neurological deficits caused by stroke; subgroups were determined by the time period elapsed since the stroke (less than and more than six months). A variety of Biometrics Ltd Goniometers were used with the DataLOG unit in order to quantify joint movement during a walking exercise. Goniometers were placed on both hips and knees of subjects, the paretic and nonparetic leg was documented and used as the primary analysis, a secondary analysis is presented as a comparison between data collected from the sub-populations.

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.
