Primary Dysmenorrhea
Heart Rate Variability as an Indicator Associated With the Improvement of Dysmenorrhea After the Warm-water Footbath
The effect of warm-water footbath in improving primary dysmenorrhea (PD) was rarely investigated previously. We aimed to exam the hypothesis that warm-water footbath is effective to reduce the pain of PD, and the effect is…

Autonomic Nervous System Disease, Healthy
Study of Norepinephrine Levels and Sympathetic Nervous System Activity
Brain and nerve cells communicate with each other by releasing and picking up chemicals called neurotransmitters. Norepinephrine is a neurotransmitter used by part of the nervous system activated during stress called the…

Chronic Pain Requiring Stellate, Thoracic, and Lumbar Sympathetic Ganglia Blockade
Measurement of the Skin Sympathetic Nerve Activity During Stellate, Thoracic, and Lumbar Sympathetic Ganglia Block
Sympathetic nerve activity can be measured transcutaneously in awake patients by computer-based filtering of raw signal obtained via skin leads attached on the chest and the right arm.

Nervous System
Assessment of Sympathetic Nervous System Activity by Microneurography Recording Technique
Obesity is the consequence of an imbalance between energy intake and energy expenditure. Recent studies have suggested that the sympathetic nervous system (SNS) may be an important determinant of the rate of energy expenditure in…
