  1. 6. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man

    Författare :Wolfgang N Löscher; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :isometric; electromyography; tremor; H-reflex; twitch; motoneuron; recruitment; la-afferents; recurrent inhibition; central fatigue; excitatory drive; gastrocnemius; soleus; triceps surae; tendon vibration; ischemia; Renshaw cellStockholm 1995;

    Sammanfattning : During a sustained contraction, the force producing capacity of a muscle gradually decreases. In order to maintain a constant force output, the neuromuscular system has to adapt to the contractile fatigue process. LÄS MER

  3. 7. Juvenile idiopathic arthritis : disease consequences and treatment effects on muscle strength, gait and pain

    Författare :Eva Broström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gait; muscle strength; kinematics; kinetics; pain;

    Sammanfattning : Juvenile idiopathic arthritis (JIA) may have a profound effect on the life of a child. Rheumatic diseases in children manifest mainly as synovitis, pain, stiffness, deformity, growth disturbances and fatigue. It is not uncommon to have reduced activity, lower aerobic endurance, and decreased muscle strength. LÄS MER

  4. 8. On the treatment of Achilles tendon rupture. A prospective, randomised study of the results after surgical and non-surgical treatment

    Författare :Michael Möller; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; rupture; score; prospective; randomised controlled trial; isokinetic; muscular endurance; magnetic resonance imaging; ultrasonography;

    Sammanfattning : Only two prospective, randomised studies have been published on the outcome after treatment for Achilles tendon rupture. The controversy regarding the optimal treatment continues. In the present study, 112 patients with acute Achilles tendon rupture were randomised and all of them were followed up for two years.

  5. 9. Response of human skeletal muscle to chronic and acute exercise and ischemia : muscle dimensions, tissue water and blood flow as measured by magnetic resonance imaging and comparative methods

    Författare :Anders T Nygren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bloodflow; cross-sectional area; exercise; fiber area; Gd-DTPA; glycogen; human; hypotrophy; intermittent claudication; ischemia; magnetic resonance imaging; metabolism; perfusion; reflex sympathetic activity skeletal muscle; training; transverse relaxation; ultrasonography.;

    Sammanfattning : The aim of this study was to investigate the response of human skeletal muscle to exercise, training and ischemi and to evaluate if magnetic resonance imaging (MRI) could be used to measure regional muscle cross-sectional area, muscle perfusion and detect muscle ischemia in patients with intermittent claudication. For this purpose studies were performed on 29 healthy young volunteers and 7 patients with intermittent claudication. LÄS MER

  7. 10. Bilateral kinetic, kinematic, neuromechanical, and muscle-tendon properties of habitual runners

    Författare :Tiago Canal Jacques; Anton Arndt; Rodrigo Bini; John Rasmussen; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Sammanfattning : Achilles tendon overuse-related injuries are a frequent problem to habitual runners. Such injuries occur more often unilaterally and its etiology is associated to overloading of the tendon tissue. Inter-limb differences during running are a possible cause for overload due to eventual differences in the mechanical loading provided to each limb. LÄS MER
