  1. 26. Neck-Injuries in Rear-End Car Collisions: Sites and Biomechanical Causes of the Injuries, Test Methods and Preventive Measures

    Författare :Mats Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The present work addresses the problem of neck injuries following rear-end car collisions. Biomechanics and sites of the injuries have been investigated. A new dummy neck has been developed and used to study the influence of different seat properties on occupant kinematics. LÄS MER

  3. 27. Advanced technology in the evaluation of chronic neck impairment

    Författare :Martin Ålund; Gunnar Németh; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : An electrogoniometrical method was modified for clinical motion analysis of the head and neck. Simultaneous measurements of neck motion range and motion pattern in the three planes could be obtained, and a graphical illustration of the movements was possible. The equipment showed high reliability and validity. LÄS MER

  4. 28. Neck function in rhythmic jaw activities

    Författare :Birgitta Häggman-Henrikson; Antoon DeLaat; Umeå universitet; []
    Nyckelord :chewing; head; human; jaw; mandible; motor control; movement; neck; temporomandibular disorders; whiplash injury; odontologi; Odontology;

    Sammanfattning : Previous studies in animals and humans show anatomic and physiological connections between the trigeminal and cervical regions. This investigation tested the hypothesis of a functional integration between the human jaw and neck motor systems in rhythmic jaw activities. LÄS MER

  5. 29. Occupant Neck Muscle Modelling in Rear-End Crashes

    Författare :I Putu Alit Putra; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Neck Muscle Responses; Finite Element; Whiplash Associated Disorders; Female; Human Body Model;

    Sammanfattning : The ultimate goal of the present research is to incorporate active and passive neck muscle effects in a female Finite Element (FE) Human Body Model (HBM). The application of interest is Whiplash Associated Disorders (WAD), which can occur in a low-speed rear-end impact. LÄS MER

  7. 30. Prevention and prediction of head and neck injury in traffic accidents - using experimental and numerical methods

    Författare :Peter Halldin; KTH; []
    Nyckelord :Head injuries; neck injuries; prevention; roll-over; motorcycle; helmet;

    Sammanfattning : Injuries to the head and neck system are potentially amongthe most serious injuries in humans, since they may damage thespinal cord. It is therefore important to develop safetysystems that can prevent injuries to the neuro- system, therebyreducing human suffering and costs to society. LÄS MER
