1. 1. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

   Författare :Catharina Hagberg; []
   Nyckelord :Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

   Sammanfattning : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. LÄS MER

3. 2. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

   Författare :Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

   Sammanfattning : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

4. 3. 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

5. 4. Effects of low-load repetitive work and mental load on sensitising substances and metabolism in the trapezius muscle

   Författare :Gerd Flodgren; Gisela Sjøgaard; Umeå universitet; []
   Nyckelord :work-related muscle pain; microdialysis; near-infrared spectroscopy; electromyography; glutamate; lactate; pyruvate; prostaglandin E2; norepinephrine; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : Low-load repetitive work (LLRW) and mental load are important risk factors for the development of workrelated muscle pain. The link between these risk factors and the development of pain is still not understood, but stimulation of chemo-sensitive receptors in the muscle probably plays an important role. LÄS MER

7. 5. Leisure and muscular performance in health and disease : a study of 40-64-year-old northern Swedes

   Författare :Björn Gerdle; Kerstin Sjögren; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Leisure; health; skeletal muscle; isokinetics; electromyography; plantar flexion; muscular fatigue;

   Sammanfattning : Categories and frequencies of leisureactivities employed by 156 randomly selected males and females aged 40-44, 50-54, 60-64 were investigated by structured interviews and were related to leisuresatisfaction, to experienced health and socio-economic status. In equal numbers (15) of males and females from each group and in 24 males (60 +_6 years) with intermittent claudication (Cl) isokinetic plantar flexion performance was investigated with registrations of peak torque (PT), contractional work (CW), active range-of-motion (RoM) and integrated electromyograms from all threee triceps surae heads.
