  1. 1. Autonomic nervous system regulation in chronic neck-shoulder pain : Relations to physical activity and perceived stress

    Författare :David Hallman; Eugene Lyskov; Bengt Arnetz; Ewa Wigaeus Tornqvist; Allan Toomingas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autonomic imbalance; Daily physical activity; Trapezius myalgia; Treatment; Parasympathetic; Sympathetic;

    Sammanfattning : Neck-shoulder pain (NSP) is a highly prevalent musculoskeletal disorder with unclear causes, and effective prevention and treatment require a further understanding of the underlying mechanisms. Aberrant autonomic nervous system (ANS) regulation is a hypothesized causal element in the development and maintenance of chronic muscle pain. LÄS MER

  3. 2. 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

  4. 3. Psychophysiological reactions to experimental stress : relations to pain sensitivity, position sense and stress perception

    Författare :Marina Heiden; Eugene Lyskov; Tohr Nilsson; Ulf Lundberg; Umeå universitet; []
    Nyckelord :public health; autonomic activity; cognitive-behavioral training; muscle oxygenation; physical activity; position sense; pressure-pain thresholds; sick leave; stress; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Stress and monotonous work contribute substantially to the development of chronic musculoskeletal disorders. Yet, the pathophysiological mechanisms underlying the process, particularly the involvement of autonomic regulation, remain unclear. LÄS MER

  5. 4. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Författare :Karin Rylander; Göteborgs universitet; []
    Nyckelord :CT afferent; thin fibre; autonomic; insula; fMRI;

    Sammanfattning : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. LÄS MER

  7. 5. Autonomic function and myocardial repolarisation. Studies in renal diseases and in spinal cord injury

    Författare :Sinsia Gao; Göteborgs universitet; []
    Nyckelord :vagus; sympathetic nervous system; repolarisation; baroreflex; reproducibility; agreement; hypertension; spinal cord injury; autonomic dysreflexia; renal failure.;

    Sammanfattning : Both experimental and clinical evidence indicates that cardiac parasympathetic markers such as baroreflex sensitivity (BRS) and heart rate variability (HRV) have significant prognostic value. Furthermore, increased myocardial repolarisation lability reflected by increased QT variability index (QTVI) has been identified as a predictor for sudden cardiac death. LÄS MER
