1. 1. Human muscle spindles : complex morphology and structural organisation

   Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
   Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

   Sammanfattning : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. LÄS MER

3. 2. 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.

4. 3. Autonomic reactivity in muscle pain : clinical and experimental assessment

   Författare :Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. The impact of visually demanding near work on neck/shoulder discomfort and trapezius muscle activity : Laboratory studies

   Författare :Camilla Zetterberg; Hans O Richter; Mikael Forsman; Malin Josephson; Hanne Mari Schiøtz Thorud; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Neck function in rhythmic jaw activities

   Författare :Birgitta Häggman-Henrikson; Antoon DeLaat; Umeå universitet; []
   Nyckelord :chewing; head; human; jaw; mandible; motor control; movement; neck; temporomandibular disorders; whiplash injury; odontologi; Odontology;

   Sammanfattning : Previous studies in animals and humans show anatomic and physiological connections between the trigeminal and cervical regions. This investigation tested the hypothesis of a functional integration between the human jaw and neck motor systems in rhythmic jaw activities. LÄS MER
