  1. 1. Physical Modeling of Brain and Head Kinematics

    Författare :Johan Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

  2. 2. Knee function, knee proprioception and related brain activity following anterior cruciate ligament injury

    Författare :Andrew Strong; Charlotte Häger; Eva Tengman; Divya Srinivasan; Eleni Kapreli; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; knee; proprioception; joint position sense; kinematics; injury prevention; sports; functional magnetic resonance imaging; brain; reliability; validity; sjukgymnastik; Physiotherapy; Sports Medicine; idrottsmedicin; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : Background: Injury of the anterior cruciate ligament (ACL) may have negative effects on the short- and long-term function and proprioception of the knee joint. However, existing tests of knee function are often sports-related and less relevant for assessment in the very long term and there remains no ‘gold standard’ test of knee proprioception. LÄS MER

  3. 3. 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.

  4. 4. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

    Författare :Marius Sommer; Louise Rönnqvist; Charlotte Häger; Nicola Hodges; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motor timing; rhythmicity; timing training; golf shot; golf swing; kinematics; precision; variability; coordination; movement dynamics; soccer; fMRI; mirror neurons; action observation; cerebellum; perception - action.; Psychology; psykologi;

    Sammanfattning : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.
