2. 1. 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.

   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accommodation; Asthenopia; Computer work; Eye-neck head stabilization; Muscle activity; Neck pain; Visual Attention; Visual demand; Visual ergonomics; Medical Science; Medicinsk vetenskap;

   Abstract : Introduction: Musculoskeletal discomfort in the neck and shoulders is common among workers performing visually demanding near work, e.g., on a computer screen, and sustained low-level muscle activity during such work can lead to work-related pain. READ MORE

5. 3. Physical exposure, musculoskeletal symptoms and attitudes related to ICT use

   Author : Ewa Gustafsson; Göteborgs universitet; []
   Keywords : Input device; Wrist movements; Electrogoniometry; EMG; Muscle activity; Thumb movements; Working technique; Information and communication technology; Computer mouse; Mobile phone;

   Abstract : High prevalence of musculoskeletal symptoms/disorders in neck and upper extremities are reported among computer users. Considering the widespread use of information and communication technology (ICT) and mobile phones becoming more and more like computers with small keyboards it is of importance to identify the factors and conditions related to this use, that influence our health.

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

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

   Abstract : 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.

7. 5. Effects of vibration on muscles in the neck and upper limbs : with focus on occupational terrain vehicle drivers

   Author : Charlotte Åström; Gunnevi Sundelin; Lage Burström; Stefan Karlsson; Karin Harms-Ringdahl; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; Physiotherapy; Sjukgymnastik fysioterapi;

   Abstract : Introduction: Occupational drivers of terrain vehicles are exposed to several risk factors associated with musculoskeletal symptoms in the lower back as well as in the neck and upper limbs. Vibration has been suggested to be a main risk factor. These drivers are exposed to both whole-body vibration (WBV) and hand-arm vibration (HAV). READ MORE
