1. Autonomic nervous system regulation in chronic neck-shoulder pain : Relations to physical activity and perceived stress
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
2. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function
Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER
3. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach
Sammanfattning : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. LÄS MER
4. Neuronal types and their specification dynamics in the autonomic nervous system
Sammanfattning : The autonomic nervous system is formed by a sympathetic and a parasympathetic division that have complementary roles in the maintenance of body homeostasis. Autonomic neurons, also known as visceral motor neurons, are tonically active and innervate virtually every organ in our body. LÄS MER
5. Autonomic function and myocardial repolarisation. Studies in renal diseases and in spinal cord injury
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
