  1. 1. Traumatic high-load injuries in the adolescent spine. Clinical, radiological and experimental studies

    Författare :Adad Baranto; Göteborgs universitet; []
    Nyckelord :Adolescence; athletes; spinal loading; back pain; disc degeneration; growth zone; intervertebral disc; MRI; nucleus pulposus; porcine spine; radiography; spine; vertebral endplate;

    Sammanfattning : Background: Disc degeneration and other radiological abnormalities are highly frequent among young athletes in sports with great demands on the back. It has also been reported that athletes with these abnormalities have more back pain than other athletes and non-athletes. LÄS MER

  3. 2. On the effect of repetitive loading on the spine of young elite athletes. Clinical and experimental studies

    Författare :Olof Thoreson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spine; intervertebral disc; athlete; young adult; low back pain; magnetic resonance imaging; porcine; repetitive loading; failure; fatigue;

    Sammanfattning : Introduction: The human spine is exposed to many different loads during daily activities and especially during sporting activities. The spine has different biomechanical properties during the lifetime and thereby responds differently to repetitive and sudden loads. LÄS MER

  4. 3. Asymmetric lateral loading of the human trunk

    Författare :Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Eccentric; concentric; isokinetic; electromyography; co-activation; trunk; spinal biomechanics; contraction patterns; lateral bending; lifting and lowering; balance; kinematics; postural control; IAP; support translation.;

    Sammanfattning : The overall aim of this thesis was to characterize the biomechanics and neuromuscular control of the human trunk in response to asymmetric lateral loading. The pulling force and strength capacities as well as muscle activation patterns, trunk kinematics and postural balance in relation to lateral trunk flexion and loading were given special consideration.

  5. 4. Static and Dynamic Load Response of the Lumbar Spine in Flexion

    Författare :Anna-Lisa Osvalder; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanical response; flexion-distraction injuries; injury; ; experimental methods; spinal segments;

    Sammanfattning : The aims of this study were to develop experimental methods for static and dynamic loading of spinal segments in vitro that would simulate flexion-distraction injuries (lap seat-belt injuries) and increase knowledge about the biomechanical response and the mechanisms of injury of the lumbar spine under static and dynamic (transient) loads in flexion. The experiments were carried out on the lumbar functional spinal unit (FSU) consisting of two adjacent vertebrae, the intervertebral disc and all intervening ligaments. LÄS MER

  7. 5. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    Författare :Johan Thorfinn; Disa Lidman; Folke Sjöberg; Henry Svensson; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Blood supply; Buttocks; Hyperemia; Ischemia; Laser-Doppler flowmetry; Microcirculation; Posture physiology; Pressure; Skin blood supply; Medicine; Medicin;

    Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER
