1. 1. Tendon transfer mechanics and donor muscle properties : implications in surgical correction of upper limb muscle imbalance

   Författare :Eva Pontén; Bertil Romanus; Umeå universitet; []
   Nyckelord :laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; hand surgery;

   Sammanfattning : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. LÄS MER

3. 2. MUSCLE TONE IMBALANCE IN HUMAN UPPER EXTREMITY An experimental study of muscle adaptation to altered tension

   Författare :Fredrik Einarsson; Göteborgs universitet; []
   Nyckelord :muscle biopsy; freeze storage; upper extremity; shoulder; human muscle; sarcomere; stress-strain relationship; stress relaxation; stiffness; elasticity; mechanical testing; morphology; spasticity; obstetric brachial plexus palsy; rotator cuff tear; tendon transfer;

   Sammanfattning : Aim: The aim of this thesis was to improve outcome after tendon transfer and rotator cuff surgery by investigating the impact on response to passive mechanical testing and change in structural characteristics associated with longstanding changes in the tension of skeletal muscle in the human upper extremities in vivo. Patients and methods: The investigational method was in vitro assessment of human upper extremity muscles. LÄS MER

4. 3. Muscle protein synthesis : effects of metabolic stress and feeding

   Författare :Inga Tjäder; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Surgical trauma and critical illness are pathophysiological conditions where the metabolic stress leads to an imbalance between protein synthesis and protein breakdown, resulting in a net loss of body proteins. A major part of the protein losses comes from skeletal muscle. Muscle depletion is associated with a high morbidity and mortality. LÄS MER

5. 4. The role of steroid hormones in skeletal muscle metabolism

   Författare :Firoozeh Salehzadeh; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Steroid hormones play important roles in the regulation of whole body metabolism. Skeletal muscle is an insulin-responsive organ with a key role in overall substrate metabolism. Disturbances in skeletal muscle metabolism, as a result of hormonal imbalance may be an underlying defect in metabolic disease. LÄS MER

7. 5. Autonomic nervous system regulation in chronic neck-shoulder pain : Relations to physical activity and perceived stress

   Författare :David Hallman; Eugene Lyskov; Bengt Arnetz; Ewa Wigaeus Tornqvist; Allan Toomingas; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autonomic imbalance; Daily physical activity; Trapezius myalgia; Treatment; Parasympathetic; Sympathetic;

   Sammanfattning : Neck-shoulder pain (NSP) is a highly prevalent musculoskeletal disorder with unclear causes, and effective prevention and treatment require a further understanding of the underlying mechanisms. Aberrant autonomic nervous system (ANS) regulation is a hypothesized causal element in the development and maintenance of chronic muscle pain. LÄS MER
