1. 6. Ambulatory Monitoring and Analysis of Surface Electromyographic Signals in Ergonomic Field Studies - Methods and Applications

   Författare :Leif Sandsjö; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trapezius; ergonomic assessment tools; long-term recording; wearable systems; EMG; musculoskeletal disorders; work-related;

   Sammanfattning : Factors contributing to and the mechanisms behind the development of work-related musculoskeletal disorders (WMSDs) are still not fully known. Increased knowledge in this area is necessary in order to recommend appropriate actions to counteract the increasing costs to society and reduce the individual suffering related to these problems.

3. 7. Endocannabinoids and N-acylethanolamines in translational pain research : from monoacylglycerol lipase to muscle pain

   Författare :Nazdar Ghafouri; Christopher J Fowler; Andrew SC Rice; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Monoacylglycerol lipase; endocannabinoid; palmitoylethanolamide; N-acylethanolamines; microdialysis; chronic widespread pain; muscle pain; trapezius;

   Sammanfattning : In the early nineties cannabinoid receptors, the main target for Δ9-tetrahydrocannabinol (THC), the psychoactive component of marijuana were identified. Shortly after their endogenous ligands, N-arachidonoylethanolamine (anandamide, AEA) and 2-diacylglycerol (2-AG) were characterized. LÄS MER

4. 8. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

   Författare :Guilherme H. Elcadi; Albert G. Crenshaw; Mikael Forsman; Martin Fahlström; Svend Erik Mathiassen; Karen Sogaard; Högskolan i Gävle; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi;

   Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Dag Rissén; Bo Melin; Ulf Lundberg; Anders Kjellberg; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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.
