  1. 1. Articular distension in arthroscopy : an experimental study on intra- and extra-articular effects of pressure

    Författare :Anders Sperber; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Arthroscopy; intra-articular pressure; in vivo measurements; knee joint capsule; tensile properties; stress-strain; multicompartmental pressures; lower leg venous blood flow; ultrasound; acromioplasty; intra-muscular pressure; fluid absorption; shoul;

    Sammanfattning : The purpose of this thesis was to analyse the effects of various intra-articular pressures (IAP) on soft tissues and to provide guidelines for the choice of safe infusion pressures during arthroscopy. The tensile properties of the knee-joint capsule were recorded from stress-strain-relaxation tests within 170 mmHg IAP. LÄS MER

  3. 2. 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.

  4. 3. Neuromechanical control of the spine

    Författare :Paul Hodges; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Control of the spine is complex. The spine is inherently unstable and dependent on the contribution of muscles. Yet there is considerable redundancy in the motor system with many muscles that act on the trunk. LÄS MER
