Background: Rhythmical massage therapy (RMT) is a massage technique used in anthroposophic medicine.

Objective: The authors aimed to investigate the physiological action of RMT on the cardiovascular system by analysing heart rate variability (HRV).

Design, Setting, Participants And Intervention: This study was a randomised, controlled and single-blinded trial, involving 44 healthy women (mean age: (26.

The most commonly used drug testing methods are based on the analysis of hair and urine using gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry or immunoassay screening. These methods are time-consuming and partly expensive. One alternative method could be the application of an "electronic nose" (eNose).

Background. Impairment of circadian rhythm is associated with various clinical problems. It not only has a negative impact on quality of life but can also be associated with a significantly poorer prognosis.

Previous studies have proposed varying causes for idiopathic sudden sensorineural hearing loss (SSNHL), including vascular occlusion, ruptured inner ear membrane, acoustic tumours and circulatory disturbances in the inner ear. The objective of this study was to characterise the autonomic regulation in 19 SSNHL patients in comparison to 19 healthy age-gender matched normal-hearing control subjects (CON) in order to improve the diagnostics of vascular caused hearing loss in SSNHL patients. A high-resolution short-term electrocardiogram (ECG) and the continuous noninvasive blood pressure signal were simultaneously recorded under resting conditions (30min).

The objective of this study was to prove the general applicability of an electronic nose for analyzing exhaled breath considering the dependency on smoking. At first, odor compounds from spices (n=6) were detected via the electronic nose and further characterized and classified with gas chromatography/ mass spectrometry to demonstrate the principle ability of the electronic nose. Then, the exhaled breath from smokers and non-smokers were analyzed to prove the influence of smoking on breath analyses with the electronic nose.

Background: Eurythmy therapy (EYT) is a mind-body therapy used in anthroposophic medicine. Recently, the authors were able to show that at comparable workloads, EYT stimulated heart rate variability (HRV) whereas conventional ergometer training attenuated HRV. Furthermore, a long-term improvement of quality of life (QoL) and stress coping strategies by EYT could be shown.
