    Sammanfattning : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linköping University is the development of an intelligent command and control system, containing vision sensors, which supports the operation of a unmanned air vehicle (UAV) in both semi- and full-autonomy modes. One of the UAV platforms of choice is the APID-MK3 unmanned helicopter, by Scandicraft Systems AB. LÄS MER

  5. 4. Sensorimotor function following anterior cruciate ligament injury : movement control, proprioception and neuropsychological perspectives

    Författare :Adam Grinberg; Charlotte Häger; Martin Björklund; Dario G. Liebermann; Clare Ardern; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ACL; knee injury; sensorimotor control; proprioception; functional test; fear; anxiety; kinematics; electromyography; EMG; electroencephalography; EEG; brain; neuroplasticity; injury prevention; Sports Medicine; idrottsmedicin;

    Sammanfattning : Background: The high incidence of anterior cruciate ligament (ACL) injuries in sports suggests an involvement of both biomechanical and neurocognitive risk factors. Athletes are constantly exposed to challenging sports scenarios, which are often characterised by high-intensity movements combined with a multi-stimuli environment and continuous psychological pressure.
