  1. 1. On the role of transversus abdominis in trunk motor control

    Författare :Martin Eriksson Crommert; Peter Engfeldt; Alf Thorstensson; Maria Ekblom; Birgitta Öberg; Martin Eriksson Crommert; Örebro universitet; []
    Nyckelord :transversus abdominis; trunk muscles; EMG; intramuscular; IAP; motor control; postural control; spine stability; postural demand; MEDICINE; MEDICIN; Medicin; Medicine;

    Sammanfattning : All trunk muscles are important contributors to spine stability. However, the deepest abdominal muscle, transversus abdominis (TrA), with its characteristically horizontal fibre orientation seems to serve a unique function in trunk motor control. LÄS MER

  2. 2. EMG and strength in trunk and hip muscles

    Författare :Eva A Andersson; Alf Thorstensson; Margareta Nordin; Eva A. Andersson; Gymnastik- och idrottshögskolan; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Neurofysiologi; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.

  3. 3. Asymmetric lateral loading of the human trunk

    Författare :Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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. 4. Hormones, muscles and oncological outcome in men with rectal cancer

    Författare :John Tapper; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Paper I. The aim was to elucidate if testosterone (T) dose-dependently increase muscle size in abdomen and pelvis, analogous to the known anabolic influence on appendicular muscles. Participants were young (age 18-50) healthy men participating in the 5a-reductase trail, a double blinded RCT. LÄS MER

  5. 5. Ventilatory aspects of sleep and activity in patients with neuromuscular disorders

    Författare :Brita Klefbeck Stridsman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; assisted ventilation; cervical cord injury; inspiratory muscle training; neuromuscular diseases; sleep; oximetry; trunk stability;

    Sammanfattning : Patients with cervical cord injuries (M) and slowly progressive neuromuscular diseases, such as prior polio and muscular dystrophy, often have decreased ventilatory capacity. This could affect both their daytime level of activity and sleep quality. LÄS MER
