PEMF stimulation of the vagus nerve with NeoRhythm: A product description and study analysis

PEMF therapy is a non-invasive technology that uses electromagnetic fields to support the body's natural processes.

The NeoRhythm device, developed by Omnipemf, is designed to stimulate the vagus nerve via the neck, a nerve that plays a central role in the autonomic nervous system and regulates functions such as heart rhythm and relaxation. The study, conducted between 25 March 2023 and 10 January 2024, examined the effect of three frequencies – 6 Hz, 16 Hz and 32 Hz – compared to a placebo group, using the NeoRhythm U-band. The results showed that the 16 Hz frequency produced significant improvements in sleep quality and general well-being, while 32 Hz was most effective for stress reduction. The report describes the device's technical details, uses and potential benefits based on these findings, and provides a balanced presentation without implying treatment of specific diseases. Additional details from Omnipemf include a 60-day risk-free trial, user satisfaction surveys, and an active Facebook group with over 10,500 members.

Benefits and effects
NeoRhythm can help reduce stress and anxiety through stimulation of the vagus nerve, which is known to influence the parasympathetic nervous system and promote calmness. The study showed that the 32 Hz group achieved an average stress reduction of 23 points on the VAS scale after one month, while both 16 Hz and 32 Hz reduced worry by 15 points. Omnipemf confirms that 32 Hz is most effective for stress reduction, while both frequencies are equally effective against anxiety, with positive effects still visible a week after use. These effects can support daily well-being and help users manage busy lifestyles.

Users have also reported increased energy and focus. One customer in a review dated February 19, 2025 mentioned that NeoRhythm helped to focus and relax after work, while another (February 2, 2025) experienced faster falling asleep and better sleep quality, eliminating the need for supplements such as melatonin. Emphasizing that regular use can improve vagal tone, which is linked to better overall well-being, Omnipemf offers "Quick Start Programs" for vagus nerve stimulation that integrate seamlessly into daily life.

The device is non-invasive and easy to use, making it accessible to people who want to integrate technology into their daily routine without complicated procedures. It requires no surgical intervention, unlike traditional vagus nerve stimulation methods, and has a favorable safety profile with few reported side effects. Omnipemf also offers a 60-day risk-free trial with easy returns, giving users peace of mind to test the device. This, combined with positive feedback from a Facebook group of over 10,500 members and weekly Q&A sessions with Dr. Igor Jerman, make NeoRhythm an attractive option for those seeking non-pharmacological solutions to support their overall health.

Technical specifications
The NeoRhythm device offers several potential benefits for overall health and well-being, based on study results, user reports and Omnipemf's descriptions. The device can help improve sleep quality by supporting the body's natural relaxation processes. In the study, the 16 Hz group reported an average increase in sleep quality of up to 15 points on the Visual Analogue Scale (VAS) after 30 days of use, indicating a very good effect on rest and recovery. This is supported by Omnipemf's website, which highlights that 16 Hz achieved the highest score in sleep improvement, especially on day 6, where most participants reported positive changes. This can be particularly useful for people who experience sleep disturbances or want deeper sleep without the use of drugs.

The NeoRhythm U-band is a portable device designed to deliver PEMF stimulation directly to the neck, targeting the vagus nerve. Here is a detailed overview of its technical characteristics, based on the study and Omnipemf's resources:

• Frequency selection: The device offers three main frequencies – 6 Hz, 16 Hz and 32 Hz – which were tested in the study. 16 Hz is recommended for sleep and general well-being, while 32 Hz is most effective for stress reduction, as confirmed by Omnipemf.

• Magnetic Intensity: Peak intensity of 2.5 millitesla (mT), which is within safe limits for PEMF therapy and sufficient to affect nerve tissue without direct contact with the skin.

• Power source: Rechargeable battery via USB-micro (some users, as in the review from 3 January 2025, have wanted USB-C for easier charging), with a battery life that supports several sessions per charge. Users report that it lasts for several days, as mentioned on January 4, 2025.

• Design: An ergonomic U-shaped band that fits comfortably around the neck. It is light and suitable for daily use, with a weight that users describe as ideal for neck positioning (January 5, 2025). The NeoRhythm Pad is a smaller variant for use on other body parts.

• Control: Controlled via a mobile app, which allows users to select frequencies and customize programmes. The app includes preset modes for sleep, relaxation and focus, as well as an advanced mode for custom sequences, which was praised in a review from January 6, 2025.

• Usage time: The study recommended 30 minutes daily, but the guidelines suggest use once or twice per day depending on need. The Omnipemf FAQ suggests flexible use with no specific upper limit, but recommends hydration before and after sessions.

• Materials: Made from durable, skin-friendly materials, although exact specifications have not been released. The package includes a charging cable, reset tool and a magnetic tube for testing.

Uno Vita AS offers three design variants by NeoRhythm with the same technical functions, but adapted to different lifestyles: the U-band for neck use, the pad for targeted use, and a third variant (not specified in detail). 

Comprehensive and detailed description

PEMF therapy has a long history stretching back to the 19th century, when early researchers such as James L. Corning experimented with electromagnetic fields to affect the nervous system. Modern research has shown that PEMF can support cell functions, blood flow and nerve activity, making it a promising field in wellness and biohacking. NeoRhythm builds on this legacy by targeting the vagus nerve, which connects the brain to many internal organs and influences parasympathetic responses such as relaxation and recovery. Omnipemf describes how the device sends targeted pulses that affect the vagus nerve's electrical signals, which can enhance its regulation of mood, digestion and immune response.

The study, which began on 25 March 2023 and ended on 10 January 2024, is one of the largest of its kind with an initial group of 485 volunteers, although the analyzes were based on 446 respondents who completed at least one follow-up survey. The participants were varied in age (19.8% between 21-40 years, 50.9% between 41-60 years, 29.5% over 60 years) and employment status (44.5% employees, 23.9% self-employed, 19.3% pensioners). About half reported existing health challenges, and two-thirds used medications or supplements, providing a broad basis for assessing the device's effects. Prof. Dr. Igor Jerman, director of the Bion Institute, emphasizes that this is the largest global investigation of PEMF on the vagus nerve, with significant improvements in sleep, relaxation and anxiety symptoms.

NeoRhythm was used in a double-blind, placebo-controlled study in which participants did not know whether they were receiving active stimulation (6 Hz, 16 Hz, 32 Hz) or placebo (0 Hz). Measurements were taken via questionnaires over five weeks, including an introductory survey, ongoing surveys (days 3, 6, 11, 16, 23, 30) and a follow-up seven days after completion. The VAS scale (0-100) was used to assess parameters such as sleep quality, general well-being, stress and worry.

The results showed clear differences between the frequencies. 16 Hz produced the greatest improvement in general well-being (9 point mean increase after 30 days) and sleep quality (15 points), especially in those with initially low well-being (VAS ≤ 50), where the increase was up to 15 points. Omnipemf confirms that 16 Hz had the highest effect on day 6 for sleep improvement. 32 Hz was most effective for stress reduction (23 points) and also reduced worry (15 points), while 6 Hz showed minimal effects and were combined with the placebo group in the analysis. The placebo group experienced moderate improvements (5 points in sleep, 11 points in worry), attributable to daily relaxation alone. Long-term effects were observed seven days after termination, with the 16 Hz group maintaining well-being levels from day 30, while stress and anxiety reductions began to decline in all groups, although relative differences to placebo persisted. This is supported by Omnipemf, which claims that positive effects can last a week after use, indicating a persistent impact on the nervous system.
Users have reported similar experiences. A review from 14 January 2025 mentioned better sleep patterns as measured by Fitbit and Withings, while another (13 January 2025) noted pain relief from bursitis and muscle problems using the NeoRhythm Pad. One customer (January 3, 2025) found that the device eliminated the need for sleeping pills after several months of use, indicating a potential "retraining" of the brain to relax naturally. Omnipemf's monthly customer satisfaction surveys (1-10 scale) provide additional insight into user experiences, and their Facebook group of over 10,500 members provides a community for discussion and support, including weekly Q&A sessions with Dr. Jerman.

NeoRhythm can be used in several ways:

• Sleep Improvement: Place the U-band around the neck or use the pad under the pillow at 16 Hz for 30 minutes before bed, as recommended in the study and Omnipemf's guidelines.

• Stress reduction: Use 32 Hz in 30-minute sessions, once or twice daily, as shown to be most effective in the study and confirmed by Omnipemf.

• Focus and energy: Choose preset modes via the app to support mental states in work or meditation, as reported by an experienced meditator (Jan 12, 2025).

• Pain Relief: Place the pad on specific areas such as the hips or back, as shown in reviews from January 4 and 7, 2025, where users experienced relief from rib pain and neck arthritis.

To maximize the effect, regular use over at least two weeks is recommended. If the effect diminishes, the guidelines suggest a break of 3-4 days before continuing. The device requires minimal maintenance - keep it dry and clean, and charge the battery when necessary.
