2. 1. Muscular activity in light manual work - with reference to the development of muscle pain among computer users

   Author : Stefan Thorn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cinderella hypothesis; myalgia; muscle rest; doublets; extensor digitorum communis muscle; motor units; computer work; intramuscular electromyography; trapezius muscle;

   Abstract : Work related musculoskeletal disorders (WMSDs) in the neck/shoulder area and the upper extremities are common among computer users, despite the relatively low muscle load levels involved. Muscle pain (myalgia), primarily experienced in the neck/shoulder area, is a frequent type of WMSD. READ MORE

4. 2. Repetitive and monotonous work among women : Psychophysiological and subjective stress reactions, muscle activity and neck and shoulder pain

   Author : Dag Rissén; Bo Melin; Ulf Lundberg; Anders Kjellberg; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Repetitive and monotonous work; women; psychophysiological stress reactions; subjective stress reactions; muscle activity; trapezius muscle; neck and shoulder pain; job rotation; Psychology; Psykologi;

   Abstract : Repetitive and monotonous work is frequently associated with neck and shoulder pain and negative psychosocial factors inducing stress reactions. The present thesis concerns the relations between psychophysiological and subjective stress reactions, muscle activity measured by surface electromyography (SEMG) in the trapezius muscle, and neck and shoulder pain in women performing repetitive and monotonous work.

5. 3. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

   Author : Qiuxia Zhang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

   Abstract : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. READ MORE

6. 4. Lateral epicondylitis : intramuscular blood flow, pressure and metabolism in the ECRB muscle

   Author : Eva Oskarsson; Karin Piehl Aulin; Eva Nylander; Örebro universitet; []
   Keywords : Lateral epicondylitis; ECRB; intramuscular microcirculation; intramuscular pressure; botulinum toxin; muscle metabolism; pain; MEDICINE; MEDICIN; Idrottsvetenskap; Sports Science;

   Abstract : Lateral epicondylitis is classified as an overuse injury and the main symptom is pain from the lateral side of the elbow. There is general agreement that the extensor carpi radialis brevis (ECRB) muscle and its proximal tendon play a central role in the development of lateral epicondylitis. However, the pathophysiology is to a large extent unclear. READ MORE

7. 5. Autonomic reactivity in muscle pain : clinical and experimental assessment

   Author : Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomic reactivity; stress; chronic pain; experimental pain; back; shoulder; neck; Physiology; Fysiologi; Physiology;

   Abstract : There are numerous indications of possible involvement of the autonomic nervous system in the genesis of chronic pain. The possibility exists that sympathetic activation is related to motor dysfunction and changes in sensory processing, which have otherwise been implicated in musculoskeletal disorders. READ MORE
