  1. 1. Sagittal plane knee translation in healthy and ACL deficient subjects : a methodological study in vivo with clinical implications

    Författare :Anil Vergis; Jon Karlsson; Linköpings universitet; []
    Nyckelord :anterior cruciate ligament; electrogoniometer system; gait; knee; kinematics; motion analysis; step ascent; step descent; translation; MEDICINE; MEDICIN;

    Sammanfattning : This study on human subjects, comprises of four cross sectional and one prospective cohort study. The general purpose of this work was to develop a technique for measuring in vivo, sagittal anterior-posterior translatory motions in the knee joint using a computerized electrogoniometer (CA-4000, OS Inc., Hayward CA, USA).

  3. 2. Velocity controlled dynamometry and gait analysis : development of methods and applications

    Författare :Lennart Gransberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dynamometry; torque; measurement error; overshoot; isokinetic; concentric; eccentric; gait analysis; three-dimensional; electrogoniometer; electromagnetic tracking;

    Sammanfattning : The isokinetic systems developed in the present study can measure torque in maximal voluntary and passive movements. The torque recordings may be combined with surface EMG recordings from pairs of antagonistic muscles involved in the movement. Healthy subjects and patients with spastic paresis have been examined.

  4. 3. Wrist and thumb joint postures and motions: Measurements using electrogoniometry and EMG

    Författare :Per Jonsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER
