LivMD - Low - Intensity Vibration

LivMD - the Real and Safe option in vibration treatment.

What is LivMD?

When a person stands on LivMD for 10 minutes, they experience 30 accelerations, or vibrations, per second at a low magnitude of 0.4g (gravitational force). That’s 1800 per minute. 

The body responds to these incredibly fast, compact, but gentle vertical vibrations by sending a mechanical signal to the cells in the body that can sense and respond to the stimulus (Woff’s law).

The involuntary muscle contractions that LivMD causes – at 30 per second — have been shown to promote muscular health.

Using LivMD for 10 minutes a day has been shown to have many health and wellness benefits for various age groups.

The low-intensity vibration signal (0.4g at 30 Hz) is considered safe* by the ISO 2631 and OSHA for use of up to 4 hours per day.

By contrast, Whole Body Vibration (WBV) machines, often advertised to have exercise, sports performance and fitness benefits, deliver a magnitude of vibration that goes well beyond the limits recommended for human tolerance by ISO 2631 and OSHA standards.

LivMD encourages muscle health

Low-intensity vibrations are a type of low-magnitude mechanical signal, delivered to the person standing on LivMD at a frequency of 30 cycles per second (Hz) and a magnitude of .4g (gravitational force).

To visualize this signal, consider that to maintain postural stability, the various muscles in your legs, back, and stomach are all undergoing the same approximate 30 small contractions per second.

These extremely small, high frequency contractions generate correspondingly small forces on the cells, including bone, fat, cartilage, and adult stem cells in the surrounding tissue. This has been shown to have a positive effect upon muscle and mobility.

LivMD is largely silent, and relaxing too. A user can talk on the phone, read or watch TV while using it. The user of LivMD feels a soothing buzzing sensation during a session.

Benefits of LivMD

LivMD is a safe* scientific-based solution for improving health and wellness:

A solution based on science
Several decades of research shows that low-intensity vibration offers a low-impact exercise that stimulates muscles and relieves minor muscle aches and pains throughout the body.

Promotes muscular health
Scientific evidence suggests that low-intensity vibration promotes redevelopment of muscle mass.

Improves blood circulation

LivMD’s patented vibration signal helps to provide oxygenated blood to muscle and tissue in areas of the body helping to reduce inflammation.

Restoration of joint mobility
LivMD has been shown to help restore motion to joints which is an important factor for anyone recovering from a joint injury or from surgery.

Adjunct treatment for obesity
LivMD is a non-pharmacological adjunct treatment for obesity which uses low-intensity vibration to stimulate muscles throughout the body.


How does it work?

Mechanical signals effect growth and renewal of tissues

The human body is designed to withstand many forces in daily life, and can adapt to differing loads generated during normal activity. These loads can be large, such as those generated while running, or they can be quite small, such as the continual tiny and high frequency signals between bones and muscles that we never have to think about. These all have a direct effect upon the growth and renewal of musculoskeletal tissues. This is very complex and involves networks of cells that are sensitive to chemical, biological and mechanical signals.

Tissues decline with age

When functional loading is removed from a human, for example with increasing age and more sedentary lifestyle, the bone and muscle tissues start to decline. We believe part of the reason for the decline is the reduction of mechanical signaling across the full range of size and frequency. The LIV signal is similar to fast firing muscle contractions and we know that these fast muscle contractions decline with age. The LIV signal directly targets cells that would normally respond to high frequency signals, that have now been lost.

25 Years of Research

Our understanding on the role of mechanical signals and their effect on tissues has been acquired over 25 years and through vibration research funded by government and other agencies. Over 110 peer-reviewed publications describe the basic science and the clinical efficacy of low-intensity vibration.

Definitions of Vibration Types


Low-intensity Vibrations are a type of low-magnitude mechanical signal, delivered by an oscillating platform at a frequency of 30-90 cycles per second (Hz). The low-intensity vibration signal Marodyne provides is designed to mimic the contractile spectrum of healthy muscle and deliver a biologically relevant signal to the cells in the body that can sense and respond to the stimulus.


Safe*, gentle and repetitive vertical vibrations promote circulation, healing and maintaining tissue.
No harmful side effects have been noted
Transmits gentle, dynamic, specific and repetitive 1D vertical displacements (vibrations) applied to the soles of the feet.
Vibration considered safe* for use and exposure of up to 4 hours per day.
Utilizes a linear actuator comprised of a magnet and voice coil (similar to stereo speaker equipment) that provides a pure acoustical signal creating only vertical movement.
Uses no electrical motors, cams, or eccentric weights.


High-intensity vibrations deliver a g-force of greater than 1-g, regardless of the frequency. Levels of vibration are typically considered as a function of magnitude (g-force), frequency (Hz) and duration of exposure (time). One “g” is equal to earth’s gravitational field, or an acceleration of 9.8 meters per second per second. Frequency corresponds to the number of cycles delivered per second. High-intensity vibration can be exceedingly dangerous, and is an etiologic factor in several pathologic conditions including low back pain1, neurovestibular disorders2, Raynaud’s syndrome3. Industries such as transportation and construction4, as well as the military5, are working towards minimizing occupational exposure to these potentially hazardous mechanical stimuli.


By contrast, Whole Body Vibration (WBV) devices are well beyond the limits recommended for human tolerance by ISO 2631 and OSHA standards.

WBV may be dangerous to use, especially for the injured or elderly.

Unsafe and aggressive vibrations are a risk to healing & frail tissue and bones, and elderly.

WBV machines list a dozen or more contraindications.

3D Vibrations are 10 times those of low-intensity vibration.

OSHA standards state that WBV devices should be considered dangerous to use, especially for the elderly.
