Summary of a blind study with 20 experimentees
In 2012, a study was conducted with 20 test subjects to analyze the effect of the RHO ROD MINI on the autonomic nervous system when exposed to electrosmog. Heart rate variability (HRV) was used as the measurement method, which measures the variation in heart rate depending on various physical stresses.
The study followed a double-blind design, in which neither the participants nor the investigators knew whether a real or a placebo device was being used.
Objective of the study
Six key questions were pursued:
Baseline measurement: First, the HRV of the test subjects was recorded in a normal state in order to create a basis for comparison for later measurements under the influence of electrosmog.
Mobile phone without protection: The HRV of the test subjects was then measured during unprotected exposure to a switched-on mobile phone in order to document possible stress caused by electromagnetic fields.
Mobile phone with placebo device: In a further step, the HRV of the test subjects was examined during cell phone exposure in the presence of an uninformed (placebo) RHO ROD MINI in order to rule out possible psychological or placebo effects.
Mobile phone with real RHO ROD MINI: The measurement was then performed during mobile phone exposure of the test subjects in the presence of an informed RHO ROD MINI.
The tests were conducted at the Holistic Center®, Prien (Germany), and at the Integral Medicine Practice in Herisau (Switzerland).

Key findings
In this scientific, randomized, placebo-controlled double-blind study, significant results were obtained with regard to cell phone calls on the one hand and the use of the RHO ROD MINI on the other hand on heart rate variability (HRV) and thus the autonomic nervous system (ANS):
- Mobile phone radiation affects the nervous system: Both phone calls without protection and those with placebo protection led to measurable stress in the autonomic nervous system. This is reflected in a deterioration in HRV values.
- Positive effect of the RHO ROD MINI: When the informed RHO ROD MINI is used, the medical parameters associated with stress improve. The autonomic nervous system reacts in a more stable and balanced manner.
- Regulatory capacity is strengthened: Phone calls with a cell phone held to the ear normally reduce the body's ability to react flexibly to stress – a so-called tendency to freeze up. With the RHO ROD MINI, however, these negative effects are not only eliminated, but even transformed into positive reactions.
