  1. 1. Towards the Inclusion of Pelvis Population Variance in Human Body Models

    Författare :Erik Brynskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Human Body Model; Sparse Principal Component Analysis; Global Sensitivity Analysis; Pelvis; Population Variance;

    Sammanfattning : With a future large-scale introduction of autonomous vehicles, the proportion of intersection crashes on the total number of motor vehicle crashes is expected to increase. The pelvis is frequently exposed to high loads in several of these impacts. LÄS MER

  3. 2. Methods for analysis of 3D movement of the trunk during treadmill locomotion

    Författare :Virgil P Stokes; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :human. trunk. Iocomotion. kinematics. 3D. treadmill Stockhtolm 1997;

    Sammanfattning : Human locomotion is a common activity and although much progress has been made in the analysis and modeling of movement, we still have a rather limited understanding of the basic mechanisms of normal locomotion. A full understanding requires the integration of the underlying neural mechanisms with the 3D dynamics (kinetics + kinematics) of locomotion. LÄS MER

  4. 3. The movement pattern of horse and rider in different degrees of collection

    Författare :Anna Byström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : While some degree of collection is considered as basic schooling work for the riding horse, learning to perform the most collected movements, such as piaffe and passage, can be a performance limiting factor for dressage horses. The aim of this thesis was to study biomechanics of horse-rider interaction in varying degrees of collection. LÄS MER

  5. 4. Assessment of acetabular cup position with computed tomography

    Författare :Henrik Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Revision of Total Hip Arthroplasty (THA) due to loosening is necessary in many patients. Diagnosis is usually late with significant bone and soft tissue destruction. Available diagnostic techniques are either not sensitive enough or too complicated and expensive for routine use. LÄS MER

  7. 5. EMG and strength in trunk and hip muscles

    Författare :Eva A Andersson; Alf Thorstensson; Margareta Nordin; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Neurofysiologi; abdominal muscles; biomechanics; electromyography; erector spinae; iliacus; iliopsoas; hip flexor muscles; locomotion; motor control; normalization; posture; psoas; quadratus lumborum; rehabilitation; running; sit-ups; strength; training exercises; u;

    Sammanfattning : The overall aim of this thesis was to study the myouelectric activity of all major muscles involved in the movements and stabilization of the trunk, pelvis and hips during training exercises, postures, motor tasks, maximal strength performance and locomotion. By use of ultra-sound, EMG electrodes could be guided safely and accurately into muscles situated even close to the spinal column, such as psoas, quadratus lumborum and deep parts of erector spinae.
