Vagus nerve stimulation is one of the best-studied fields of modern neuromodulation — with results from over 60 clinical trials. Amelle works exactly here: with the 3-in-1 combination of TENS, EMS and 108°F deep heat directly at the upper neck (C0–C2), where the vagus nerve is easiest to reach.
Get yours nowResearch on vagus nerve stimulation consistently shows measurable effects across three major areas. These are exactly the mechanisms Amelle targets at the neck.
Cognitive performance, emotional balance and mental health — the nerve helps the brain restore healthy messenger patterns.
More energy, physical performance, immunity and relief from post-viral symptoms through dampened inflammatory signals.
Heart, gut and lung function plus recovery capacity — through a balanced autonomic nervous system.
Vagus nerve stimulation influences signaling pathways connecting the brainstem with regions involved in attention, mood and emotional processing. Researchers examine changes in neural activity and neuroplasticity over time.
The vagus nerve participates in neuroimmune communication. Research has investigated how stimulation may influence inflammatory pathways and signaling molecules such as IL-6.
Heart rate variability is used to examine autonomic activity. Vagus nerve stimulation studies evaluate how stimulation affects sympathetic and parasympathetic responses.
"The vagus nerve is the most important lever of our rest system. What convinces me about the research is the independent, placebo-controlled data on heart rate variability — this is exactly where a device like Amelle comes in: precisely, at the right spot."Dr. Karen Mitchell, MD · Specialist in the autonomic nervous system
The vagus nerve is the body's communication axis: it connects the brain with vital organs and controls heartbeat, digestion and the inflammatory response. Amelle modulates it where it runs closest to the surface — at the upper neck (C0–C2) — with three methods at once: TENS (gentle impulses signal "all is safe"), EMS (releases the deep muscles that pinch the nerve) and 108°F deep heat (activates the rest system and boosts circulation).
A selection of documented effects from placebo-controlled trials on vagus nerve stimulation — the mechanism Amelle is built on.
Results from clinical trials on vagus nerve stimulation in specific study populations. Individual results may vary.
The parasympathetic nervous system is the body's own rest mechanism, and HRV is its indicator. In a clinical trial, a one-hour vagus nerve session changed all HRV parameters positively compared to placebo: high-frequency HRV rose significantly while low-frequency HRV dropped — a clear sign of a balanced nervous system.

Vagus nerve stimulation activates the nerve, raises vagal tone and inhibits inflammatory cytokines — both important mechanisms against anxiety. The improvement persisted even one month after the end of treatment.

In the trial, participants reported lasting improvements a full week after treatment ended (Pichot fatigue scale, about −48%).

Vagus nerve stimulation raises the parasympathetic branch, reduces inner restlessness and improves sleep scores — measured at several time points over four weeks.

The most robust trials on vagus nerve stimulation follow the gold standard: double-blind, placebo-controlled, under ethically approved, real-world conditions — with objective biomarkers instead of self-report alone.
Vagus nerve stimulation is studied at renowned universities and hospitals worldwide — across a wide range of clinical populations.
Evidence of improvements in attention, processing speed, memory, mood and sleep — by activating brainstem centers (noradrenaline, acetylcholine) and dampening neuroinflammatory pathways.
