Position of the Wrist Associated with the lowest Carpal Tunnel Pressure: Implications for Splint Design; N Weiss, L Gordon, T Bloom, Y So, D Rempel; Journal of Bone and Joint Surgery 1995 Vol 77-A, No. 11, pp 1695-1699 To determine the position of the wrist that results in the lowest carpal tunnel pressure, twenty control subjects and four patients who had carpal tunnel syndrome were evaluated with use of a new, dynamic method that continuously measures carpal tunnel pressure throughout the range of motion of the wrist. A Biometrics Ltd two-axis electrogoniometer was used to measure continuously the flexion or extension angle as well as the radial or ulnar deviation of the wrist.

The Use of Therapeutic Electrical Stimulation in the treatment of Hemiplegic Cerebral Palsy; M Hazelwood, J Brown, P Rowe, P Salter; Developmental Medicine and Child Neurology, 1994, 36:661-673; 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.

Single Case Experiment to Investigate a Short Term Stretching Programme for Ankle Equinus; K Rome, A Clark; British Journal of Podiatric Medicine 1994, 49(2): 19-23; Biometrics Ltd electrogoniometers were used in this study is to evaluate a short term stretching programme for ankle equinus, using a high load, brief stretch technique. The single case study has demonstrated the flexible electrogoniometer as a reliable instrument which is easy to use in the clinical setting.

Disorders of the Neck and Upper Limbs in Women in the Fish Processing Industry; K Ohlsson, GA Hansson, I Balough, U Stromberg, B Palsson, C Norander, L Rylander, S Skerfving; Occupational and Environmental Medicine 1994, 51: 826-832 Wrist angles of the dominant hand were measured for 32 randomly selected women during a total of 40 representative 20 minute work periods. A Biometrics Ltd twin axis electrogoniometer and a Datalogger were used for recording the flexion and extension, and the deviation angles of the wrist. The angular distributions, the angular velocity distributions, and the power spectra, were calculated to characterize the wrist movements during work.

Clinical Methods of Goniometry: a Comparative Study; J Goodwin, C Clark, J Deakes, D Burdon, C Lawrence; Disability and Rehabilitation 1992; Vol 14, No.1; pp 10-15 This investigation compared the reliability and interchangeable use of three currently available goniometers - a universal goniometer, a fluid goniometer, and a Biometrics Ltd electrogoniometer. Three consecutive readings of the active range of movement of the right elbow joint were taken from each of 23 healthy female volunteers; three experienced observers each used each type of goniometer on two occasions. Significant intertester differences were found to exist for both the universal and fluid goniometers. However, no significant differences were found between any of the testers with respect to the electrogoniometer. It therefore appears reasonable to suggest that, with respect to reducing intertester differences, the electrogoniometer is preferable.

Dynamic Analysis of Wrist Circumduction: a New Application of the Biaxial Flexible Electrogoniometer; H Ojima, S Miyake, M Kumashiro, H Togami, S Meng, K Suzuki; Clinical Biomechanics 1991; 6: no 4; 221-229 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.

Flexible Goniometer Computer System for the Assessment of Hip Function - The Clinical Biomechanics Award 1988; P Rowe, A Nicol, I Kelly; Clinical Biomechanics 1988, 4:68-72; 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.

Ambulatory Monitoring of the Pressures Beneath Compression Bandages; S Sockalingham, J Barbenel, D Queen; CARE Science and Practice, vol 8, no 2: 75-79; 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.
