  1. 11. On spinal mechanisms for reflex control in man : modulation of Ia-afferent excitation with changes in muscle length, activation level and fatigue

    Författare :Maria M. Nordlund; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle; Medicin Teknik; Medicine Technology; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle;

    Sammanfattning : To control muscle force, neural activation has to take alterations in muscle mechanics into account. This thesis assesses modulations in excitatory efficacy of Ia-afferents during muscle length changes at different levels of voluntary activation and during fatigue. LÄS MER

  3. 12. MUSCLE STRENGTH, GROSS MOTOR FUNCTION AND GAIT PATTERN IN CHILDREN WITH CEREBRAL PALSY

    Författare :Meta Nyström Eek; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; child; muscle strength; reference values; cerebral palsy; motor skills; gait; resistance training;

    Sammanfattning : Aim The main purpose was to explore the relationship between muscle strength and walking ability in children with bilateral spastic cerebral palsy (CP), and to analyse whether muscle strength training can improve walking ability. Another aim was to establish normative values for muscle strength in terms of torque in typically developing children and adolescents, and in relation to sex, age and body weight. LÄS MER

  4. 13. Estrogen receptors in skeletal muscle : expression and activation

    Författare :Anna Wiik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : There are two estrogen receptors (ERs), ERalpha and ERbeta, which are ligand activated transcription factors. Estrogen, which exerts its effect via ERs, is not only a female reproductive hormone, but acts almost ubiquitously in the human body and is involved in physiological and pathological states in both males and females.

  5. 14. Polymyositis and dermatomyositis : inflammation, muscle structure and immunosuppressive treatment

    Författare :Ingela Loell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Polymyositis and dermatomyositis are chronic, inflammatory disorders characterized by muscle weakness, low muscle endurance and by inflammation in skeletal muscle tissues. The pathogenesis is not completely understood and several mechanisms are believed to be involved. LÄS MER

  7. 15. Charcot-Marie-tooth disease : muscle morphological and neurophysiological aspects

    Författare :UllaBritt Ericson-Gripenstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Charcot-Marie-Tooth disease (CMT) is a common inherited disorder of the peripheral nervous system characterised by distal weakness and muscular atrophy, sensory disturbance of the distal limbs, diminished or absent deep tendon reflexes and often pes cavus. CMT is divided into two major groups based on clinical and electrophysiological findings. LÄS MER
