METHOD AND APPARATUS OF ASSESSING OR MONITORING SKIN SYMPATHETIC NERVE ACTIVITY IN A LIVING SUBJECT

摘要

A method of assessing or monitoring the normal skin sympathetic nerve activity in a living subject, the subject having a skin, comprises assessing or measuring electrodermal activity, wherein the electrodermal activity is skin conductance, galvanic skin response, electrodermal response, psychogalvanic reflex, skin conductance response, sympathetic skin response or skin conductance level. Skin conductance may be assessed by calculating skin conductance fluctuation peaks per time unit, and when the skin conductance fluctuations peaks are above a certain predefined value, the normal skin sympathetic nerve activity is defined in an analyzing window with a length of about 15 to 60 seconds, the normal skin sympathetic nerve activity is assessed as being obtained or successful. Alternatively, the skin conductance may be assessed by calculating rise time of the mean skin conductance level, the area under the skin conductance fluctuations or the size of the amplitude of the skin conductance fluctuation.
