Vibration Plate Buying Guide [2023 Update]
You may get confused by so many vibration plate models in the market and feel difficult to choose one, or you don't even know what product aspects to look at. If so, this vibration plate buying guide is for you.
First of all, choosing a vibration plate is about choosing vibration frequency, amplitude and the motion pattern.
You should know how frequency and amplitude relate to vibration intensity and how they interact with your body.
Vibration is about frequency and amplitude.
The motion pattern tells the direction that vibration moves the user's body.
It is not difficult to understand these parameters when you know the type of vibration plate.
Based on their mechanics, vibration plates can be categorized into 4 types:
- Pivotal Oscillation Plate
- Linear Vibration Plate
- Complex Motion Plate
- Solenoid Oscillation Plate (rare)
Each type has its own distinctive motion pattern and frequency range.
The slow-motion animations below visualize the motion patterns of these 4 types of vibration plate.
Pivotal Oscillation
Linear Vibration
Complex Motion
Solenoid Oscillation
Above animations run at 3Hz or 4Hz frequency.
In reality, a pivotal oscillation plate runs from 5Hz to 15Hz; and a linear vibration plate 15Hz to 50Hz.
Vibration plates of the same type have similar characteristics, tech specs, functions and influences to user's body.
This buying guide provides you with the essential knowledge and insights of vibration plate models available in the market. For each type of vibration plate, its mechanics, movement patterns, parameters, and usabilities are explained in detail.

Most vibration plates in the market are redundant white-label generic OEM models. Sellers purchase existing models designed by OEM factories in China, put on their own labels, and sell in their own countries. Some sellers make minor changes to the cosmetic appearance, others just simply put on their logos.
Sellers often come up with their own terminologies in reference to their vibration plate models, such as 3D, 4D, tri-planar, vertical, wave, pulse, and turbo, etc. These terminologies are created for marketing hype. They do not provide clear information about the motion patterns of the vibration plates. Some are even misused or misleading.
Although it may sound complicated, the motion patterns of various vibration plates are actually easy to understand once you know what kind of mechanical device is used to generate the vibration.
In general, there are ONLY TWO main types of core mechanical devices adopted by manufacturers to make various models of vibration plates.
1) Planar 4-bar linkage device, which generates pivotal oscillation.
2) Eccentric wheel + spring device, which generates linear vibration.
Most vibration plate models employ one of these two devices. Some vibration plate models employ both type of devices to generate complex motion.
The 4-bar device and the eccentric wheel device are distinctively different from each other. When selecting a vibration plate, you should know which device is in the machine.
Other types of vibration devices are rarely used to make whole body vibration plates.
If you want to use a vibration plate in your home, you should be aware of the potential negative impact that vibration may have on you house structure. You should use a vibration plate on a solid floor.
- Vibration plates can shake your house!
-
Vibration plates should be used on a solid floor that resists vibration, like a concrete floor, or a wood floor that is tightly attached to a concrete substrate.
If you live in a house with a wood frame structure, you should put your vibration plate in the basement or the garage. If used on a wood frame floor, your vibration plate will vibrate your floor. The floor joist will further transmit the vibration to the connecting stud walls, shaking your house. Over time, vibration can loosen your house structure.
Don't use a vibration plate in a mobile home.
In some apartment buildings, using a vibration plate may bother your neighbors.
If needed, you can put an anti-vibration cushion, such as a thick EVA foam exercise mat beneath your vibration plate to absorb the vibration transmitted to the floor.
A large size exercise mat, like 4'x4 with thickness between 1/2" and 1" may be a good idea.
While anti-vibration cushion absorbs some vibration transmitted to the floor, it also reduces a some vibration intensity.
If necessary, consult a housing structure expert about using a vibration plate in your house.
Vibration Mechanics & Motion Patterns
Pivotal Oscillation
Pivotal oscillation plate moves like a sea-saw. Its upper platform oscillates around a fixed center pivot axis, so literally, pivotal oscillation.
The mechanical device that generates pivotal oscillation is a planar 4-bar linkage device. This type of machine is usually designed to oscillate at low frequency and high amplitude.
Pivotal oscillation plates are the mostly sold type of whole body vibration plate in the market.
A pivotal oscillation plate resemble an oil pumpjack, which is also a 4-bar device. Only the pivotal oscillation plate moves much faster.
Pivotal oscillation is actually not vibration. It lacks the characteristics of vibration, except for its reciprocating movement. Unlike vibration, pivotal oscillation plate does not have damping effect.
Manufacturers and sellers usually name this type of machine as a vibration plate. Nevertheless, the market has adopted pivotal oscillation plate as a type of vibration plate.
When you stand on a pivotal oscillation plate, the effect of up-and-down movement is mainly on your feet and legs. Less vertical movement is transmitted above your waist.
Above the waist, your body moves mostly in horizontal direction. You feel your upper body swinging left and right.
Since most of its vertical movement does not transfer over to your upper body, pivotal oscillation plate usually don't upset your stomach and brain.
Most pivotal oscillation plates are designed to oscillate at low frequency (less than 14Hz) and high amplitude (between 8mm and 10mm)
A 4-bar device can also be designed to produce left-right lateral oscillation.
Some manufacturers make vibration plates with two 4-bar devices built in: one that produces pivotal oscillation, the other lateral oscillation. These are complex motion type vibration plates.
Lateral oscillation may harm your knee joints. More details will be discussed later.
Linear Vibration
Linear vibration plate moves mainly in the vertical direction, with modest horizontal movement. This type of machine is usually designed to vibrate at high frequency and low amplitude.
The mechanical device that generates linear vibration is an eccentric wheel + spring device.
The rotation of the eccentric wheel creates unbalanced centrifugal force that moves the upper platform on a cycle path. The springs support the upper platform and regulate the movement to vertical direction. The spring force is proportional to its length change. In other words, the force and length change have a linear relationship. Therefore, this type of movement is called linear vibration.
Linear vibration plates can transmit vibrations to your upper body and head. Some people may feel nauseous and dizzy when their stomach and brain are vibrated.
To effectively reduce or prevent the vibrations from transmitting to your upper body, you can bend your knees or lift your heel on the vibration plate. Knee bending is the best pose to exercise your lower limb muscles.
Linear vibration plates can be designed to achieve higher vibration frequencies, but lower amplitudes. Most linear vibration plates in the market are designed with a frequency range between 15Hz and 50Hz, and a maximum amplitude from 2 to 3mm.
Confusing Terminologies
What is a vertical vibration plate?
Some manufacturers call their linear vibration plate model as vertical vibration plate.
Vertical movement is what we need for a whole body vibration plate, because it works against gravity and maximize the influence that vibration acceleration puts on our body. Vertical movement acceleration is safe because our musculoskeletal structure is designed to overcome gravity.
(exaggerated animation)Linear vibration actually moves in both vertical and horizontal directions, as demonstrated here in an exaggerated animation. The movement technically takes a vertical oval path. The springs regulate the movement more on the vertical direction and restrict the movement on the horizontal direction.
What is a 3D vibration plate?
Some manufacturers call their linear vibration plates (eccentric wheel type) 3D vibration plates, probably to make them sound different from a pivotal oscillation plate models. The term "3D" does not refer to any type of technical movement or function of a vibration plate. In the world we live, everything is 3D.
Additionally, you may see some sellers use the term tri-planar to refer to their linear vibration plates.
You may get further confused because pivotal oscillation plates with 2 or 3 motors (complex motion) are also called 3D or 4D vibration plate models by their manufacturers.
Therefore, terminologies like 3D, 4D, vertical vibration do not tell if a vibration plate is a linear vibration type or a pivotal oscillation type.
Some sellers call left-right lateral oscillation "linear vibration", probably because such a movement sounds linear, compared to pivotal oscillation. This can cause a confusion.
Complex Motion
Complex motion model combines planar 4-bar device(s) and eccentric wheel device to generate a complex motion pattern.
There are three kinds of combinations:
- Combination of two 4-bar devices. One creates pivotal oscillation, the other lateral oscillation. Two motors are used, one for each device.
- Combination of a 4-bar device and an eccentric wheel device, creating a complex pivotal oscillation and linear vibration. In the design of this mix, the intensity of linear vibration is usually compromised to make it to work. Two motors are used, one for each device.
- Combination of two 4-bar devices PLUS an eccentric wheel device, creating a complex pivotal oscillation, lateral oscillation and linear vibration. In the design of this mix, the intensity of linear vibration is usually compromised to make it to work. Three motors are used, one for each device.
The above drawing demonstrate a complex motion OEM model developed by JTME. The 4-bar device on the left creates a pivotal oscillation, while the 4-bar device (with a long coupler-bar) on the right creates a left-right lateral oscillation.
Lateral oscillation can be harmful to knee joint. It can cause the wear and tear between the patella (kneecap) and femur trochlear groove, damaging the cartilage. It also improperly stresses the knee ligaments (LCL, MCL, ACL and PCL) that connecting the femur and tibia.
The musculoskeletal structure of our knee joint is designed for making up-and-down and forth-and-back movements. Forceful left-and-right lateral movement at our knee joint is against its designed purpose and mechanics. This kind of posture should be avoided in our daily physical activities, let alone doing it on a vibration plate that moves in a rapidly repetitive pattern.
LifePro Rumblex 4D vibration plate, for example, comes with lateral oscillation. The seller call their lateral oscillation as "linear'. Probably because the horizontal movement sounds like linear, but it is misleading.
Lateral oscillation induces very little skeletal muscle contraction.
An issue with a complex motion vibration plate is that each motion device employs a separate motor, so the motions are not synchronized. Such a complex motion vibration plate does not have a consistent rhythm and direction pattern. Our neuromuscular system may not get trained and enhanced from this type of random motion pattern. Also, without a consistent movement direction, you can not design a proper pose to utilize the vibration movement.
To create a complex motion with a rhythm pattern, all motions need to originate from a single motor. Just like a 3-axis CNC machine, the rotations of all axes originate from a single motor. It would be costly to make such a single motor synchronized vibration plate to generate a complex motion. There is probably no valuable to create such a complex motion, because there is no evidence that complex motion is better than simple motions like pivotal oscillation and linear vibration, for health improvement purpose.
On a simple linear vibration plate or a simple pivotal oscillation plate, with a consistent movement pattern, you can design your exercise poses to target certain muscle groups, for instance performing L-squat to enhance muscles around the hip joint. However, on a complex motion vibration plate, you cannot develop an exercise pose with a clear objective.
Manufacturers tend to call their complex motion vibration plates 3D or 4D models.
We do not recommend complex motion types of vibration plate because their motions are not synchronized.
Due to its random motion pattern and movement direction, it is not possible to develop good exercise poses on this type of vibration plate. Improper pose can hurt your muscles, bones and the connecting tissues.
We are strongly against using lateral oscillation motion.
Lateral oscillation can hurt your knees.
Our recommendation is either a simple pivotal oscillation plate or a linear vibration plate. These models are reliable and have abundant ratings and feedback from a large population of users.
Solenoid Oscillation
Solenoid oscillation device is an actuator suitable for generating reciprocating movement for a vibration plate.
Compared with eccentric wheel device, solenoid device can achieve higher frequencies but much lower amplitudes. Due to its low amplitude, a vibration plate of this type is called low intensity vibration plate.
Because of its low amplitude, solenoid vibration plate does not induce much muscle contraction.
There are not many vibration plate models adopt solenoid oscillation device, probably only two.
Juvent vibration plate is probably one. Although not disclosed in its product literature, from a patent document found in Juvent's website, we can guess that Juvent vibration plate employes solenoid device to generate its oscillation.
Another vibration plate model that may adopt solenoid oscillation device is Marodyne. There is not much product information provided in its website. However, Marodyne is somehow related to Juvent. It looks like Marodyne is a newer version of Juvent. The two models looks very similar.
Unlike pivotal oscillation plates and linear vibration plates that have been approved for their safety and effectiveness by a large user population, solenoid oscillation plate lacks real life testimonials for their effectiveness. However, due to their extremely low intensity nature, this type of vibration plate should not have much safety concern.
4-bar devices and eccentric devices are the most practical mechanical devices for whole body vibration plates.
Besides 4-bar device, eccentric wheel device and solenoid device, there are other mechanical devices that can produce reciprocating movements, but most are not necessarily suitable or practical to be adopted to make whole-body vibration plates. Mechanical actuators, such as gear rack, piston and cam devices are commonly used to make reciprocating movements, but if used in fast moving vibration plate, they can wear out in a short period of time. They were used in some early versions of low frequency vibration plates, and later discontinued.
Vibration Parameters & Tech Specs
Now that we have reviewed all types of vibration plates, our next step is to examine the vibration parameters of different models.
Vibration frequency and amplitude are the most important parameters for a vibration plate.
Vibration Frequency
Vibration frequency indicates how fast the vibration moves - in other words, how many reciprocating movements occur per second.
[Example] A linear vibration plate running at 30Hz frequency means that it moves up-and-down 30 times in one second.
Frequency of Pivotal Oscillation
Pivotal oscillation plates are usually designed to run at a lower frequency range, from 5Hz to 15Hz.
The animations below demonstrate a pivotal oscillation plate running at 3Hz is faster than one running at 1Hz.
 |
|
| Frequency = 1Hz Upper plate moves up-and-down 1 time in a second. |
Frequency = 3Hz Upper plate moves up-and-down 3 time in a second. |
Frequency of Linear Vibration plate
Linear vibration plates are usually designed to run at a higher frequency range, from 15Hz to 40Hz.
The animations below demonstrate a linear vibration plate running at 4Hz is faster than one running at 1Hz.
 |
|
| Frequency = 1Hz Upper plate moves up-and-down 1 time in a second. |
Frequency = 4Hz Upper plate moves up-and-down 4 time in a second. |
Some vibration plate models are designed to run at a fixed frequency. Some vibration plate models are designed to offer adjustable frequency.
For a home use linear vibration plate, we would recommend adjustable frequency models. Adjustable frequency allows new users to start with a lower frequency setting and ease into higher frequency settings. It also allows users to choose different frequency for different exercises. People with certain medical conditions are not able to endure high frequencies. An adjustable frequency vibration plate can give them the chance to discover their personal preference.
Vibration plate with adjustable frequency are usually designed with built-in programs.
The frequency range of a linear vibration plate is usually designed to match the natural frequency of human soft tissues to achieve resonance effect.
Speed level is not comparable from model to model
Some vibration plate models use speed level to indicate the vibration speed. Speed level is not a standard unit. It is defined by each manufacturer. You cannot compare speed level from model to model. A model with 99 speed level does not mean it is fast than another model with 20 speed level.
[Example] A vibration plate has its speed level designed as ranging from 1 to 99 to control the adjustable frequency range from 5Hz to 10Hz. At speed 99, the vibration runs at 10Hz.
Another vibration plate has its speed level designed as ranging from 1 to 20 to control the adjustable frequency range from 5Hz to 14Hz. At speed 20, the vibration plate runs at 14Hz.
This example demonstrates a machine with 99 speed level is actually slower than a machine with 20 speed level.
Some manufacturers configure their low frequency vibration plate to have higher speed level. This actually make the machine awkward to use. It is only for a marketing hype.
Vibration Amplitude
Vibration amplitude is the maximum vertical travel distance of the upper platform of a vibration plate.
For example, a pivotal oscillation plate has an amplitude of 10mm. This means the distance between the highest position and the lowest position of is upper platform is 10mm.
Amplitude of Pivotal Oscillation Plates
Pivotal oscillation plates can be designed to achieve higher amplitudes, usually in a range between 8mm and 10mm.
Amplitude of Pivotal Oscillation Plate
Due to its see-saw motion pattern, the amplitude at the center pivotal axis is zero, and towards the edges of the platform, the amplitude reaches its maximum.
Pivotal oscillation plates do not have an adjustable amplitude setting.
Amplitude of Linear Vibration Plate
Linear vibration plates are usually designed with a lower amplitude, mostly less than 3mm.
Amplitude of Linear Vibration Plate
For a linear vibration plate, the amplitude is evenly distributed on the entire exercise board.
Some linear vibration plate models are designed to have two amplitude settings, e.g. model VT003F and VT007 by Vibration Therapeutic.
®G-force
G-force is an important indicator of vibration intensity. Some manufacturers don't provide the G-force value of their vibration plates, but if you know the frequency and the amplitude, you can calculate the G-force of your machine.
So called G-force, it is actually not a force, but an acceleration rate expressed in the unit of G, the acceleration rate of gravity.
G-force provides a good way to compare the intensity of different vibration plates.
Motor Power
For a pivotal oscillation plate, a 200W - 300W motor is sufficient for up to a 300 LB user's body weight.
For a linear vibration plate, a 80W - 120W motor is sufficient for up to a 300LB user's body weight.
The user's body weight recommendation also relates to the structure and the build of the machine.
You don't necessarily need to choose a vibration plate with a large motor. Motor capacity is meant to suit the designed frequency, amplitude, structure, user's body weight, and the anticipated potential load surge. Manufacturers should all know to properly select a suitable motor.
Commercial grade linear vibration plates are usually designed with bigger motors (up to 300W), because they are designed with bigger eccentric wheels and springs with higher stiffness, in order to achieve better stability and less amplitude yield to heavier body weight.
[Example] Power Plate Model Pro7, a large commercial grade vibration plate, has a nominal operation power in the range between 160W and 265W.
[Example] VT007 linear vibration plate has a 80W motor (rated capacity). Its operation power consumption is between 50W and 60W.
Linear vibration plates employ smaller motors than pivotal oscillation plate because of their flexible link system. For a linear vibration plate, the load change does not affect the power consumption.
Pivotal oscillation plates are usually designed with larger motors to provide the needed buffer for load surge.
Usability & Purpose
Exercise Board Size
A large and flat exercise board is preferable for a whole body vibration plate. Large and flat board can accommodate many exercise postures.
Obviously you will also need to decide if a large and heavy machine is a good fit for your house.
Sea-saw Motion vs Vertical Motion
Pivotal oscillation plates have a sea-saw motion which limits many exercise poses.
Linear vibration plates have evenly distributed vertical vibration on the entire upper platform, which can accommodate more exercise postures.
Handrail
Handrail is a good feature for physically weak users.
Handrail limits the use of vibration plate for many poses. It also makes the machine heavy and bulky.
To avoid user tip-over, vibration plates with a small base and light weight may not be suitable for installing a handrail.
With out a handrail installed on a vibration plate, you can hold on to a heavy table or wall-mounted bar if needed. You can also free up your hands so you can hold a pair of dumbbells.
Floor Shaking Issue
You need to be aware about floor shaking issue when using a vibration plate in your home.
Vibration plates should be used on a solid floor, like a concrete floor or a wood floor that is tightly installed on a concrete substrate.
If using a vibration plate on a frame structure wood floor, the machine can vibrate the floor and the connecting structure. Overtime, vibration will loose the house structure.
A high frequency linear vibration plate creates more impact on a house than a low frequency pivotal oscillation plate.
Basements and garages are the best places to use a vibration plate.
If necessary, you can use a thick exercise mat beneath your vibration plate to absorb some downwards vibration.
Machine Jump or Drift
Home-use vibration plates are light weight, and not attached to the floor. If your body weight is not on the machine, the vibration force can overcome the machine weight and cause the machine to jump or drift on the floor.
It is not an issue as long as you keep your body on the machine when it is running on vibration.
It is recommended to use your vibration plate on a carpeted floor. The carpet provides some buffer and friction that can prevent the machine from jumping or drifting.
The video below demonstrates how a pivotal oscillation plate starts to jump when the frequency reaches a certain value when there is no user standing on it.
pivotal oscillation plate jumping on the floor
Always keep your body on the machine when it is running. Your body weight will prevent your vibration plate from jumping or drifting.
Vibration Noise
Although vibration always generates noise, good quality vibration plates produce less mechanical noise. Excessive mechanical noise most likely indicates a quality problem.
Pivotal oscillation plates usually generate less noise because they vibrate at lower frequency (below 15Hz). You can watch TV while using a pivotal oscillation plate.
Linear vibration plates generate significantly more noise when running above 30Hz, but usually not louder than a vacuum cleaner at the highest level. Should be acceptable for home-use.
At the same noise level (dBA), human ears perceive higher frequency noise as louder and more annoying.
Floor vibration induced by vibration plate can also generate noise. Use your vibration plate on a solid floor to avoid floor vibration.
EMF
Vibration plates produce electric and magnetic fields (EMF), just like other common household electric appliances.
The type of EMF generated by a vibration plate is called extremely low frequency EMF. Scientists have not found this type of EMF posing any safety concern to humans.
EPA advises that there is no clear scientific evidence that EMF affects health. EPA does not define a safe or hazardous level of EMF exposure.
Vibration Plate Design Styles
Vibration plates have many design styles. Of the hundreds of models available in the market, most design styles are just redundant. Pay attention to the size of the exercise board when choosing a design. If you have a balance issue, choose one with a handrail.

Common Misconceptions about Vibration Plate
- Vibration plates are complicated machines.
- Vibration plates are high tech products.
- The parameters of vibration plate are proprietary information.
- The efficacy of vibration therapy has been scientifically approved.
- Vibration motion pattern, the more complex the better.
- Vibration plates with 180 speed levels runs faster than vibration plates with 60 speed levels.
- A 10 minute vibration exercise equals a 60 minute jog.
What Vibration Plate to Choose?
We have discussed types of vibration plate, parameters and usability. These are the major aspects to check and confirm for making a choice.
Vibration frequency and amplitude are the most important factors. These two parameters are the key experimental conditions that scientists select to conduct clinical trials.
Linear vibration plates produce vibration in a frequency range that can more effectively stimulate muscle contraction.
You know your own health conditions the best. Now you also know all these major aspects of a vibration plate. Hopefully you can connect the dots and choose the right vibration plate for your objectives.
Out of the 4 types of vibration plate, we don't recommend complex motion models. There is not any scientific study conducted to test whether complex motion has any advantage over simple pivotal oscillation or linear vibration. Complex motions created by multiple motors are not synchronized, which poses another disadvantage.
Additionally, we strongly oppose using lateral oscillation, which we believe is harmful to the knee joint. Unfortunately manufacturers like to add this type of motion to their complex models, in order to make it "3D" or "4D" for a marketing hype.
Our general recommendation for anyone interested in exploring vibration therapy is either using a simple pivotal oscillation plate or a linear vibration plate. The shared user experiences of these two types of machines are abundant on the internet. They have been proved safe to use.
We consider linear vibration deserve a close look. Scientists usually select linear vibration plates for their research trials. Be aware on a linear vibration plate, vibration can be transmitted to your upper body and upset your stomach and brain, causing nausea and dizziness. You can bent your knee and tiptoe to avoid vibration being transmitted to your upper body. People with serious motion sickness should not use linear vibration plates.
Most sellers offer free 30 day return policy. You can certainly take the advantage of this favorable policy and give a vibration plate a try.
Just please keep the machine and the packaging in good condition in case you need to return. This is a nice way to show your appreciation to the sellers. It costs them round-trip shipping and handling for a return. Even for orders fulfilled by Amazon, all shipping costs are actually charged to the sellers.
Introducing VT Vibration Plates
Vibration Therapeutic® make both pivotal oscillation and linear vibration models. We only focus on a few models with optimized structures and refine materials, and bring in new concepts, innovations and proprietary design to make these models better.
We strongly and confidently recommend our pivotal oscillation plate model VT027 and linear vibration plate model VT007.
Pivotal Oscillation Plate VT027
VT027 is our ultimate design for a pivotal oscillation plate after many years of experience making other pivotal oscillation plates of similar parameters.
The biggest difference for VT027 when compared with other pivotal oscillation plate models in the market is its patented aluminum alloy twin-coupler design.
Other pivotal oscillation plates use regular single coupler made of nylon and sheet metal which will reach material fatigue and break much sooner.
With the same frequency, amplitude and exercise board size, VT027 is the shortest in height among all pivotal oscillation plates you can find. This is also because of its patented twin-coupler design.
Linear Vibration Plate VT007
VT007 is re-engineered from our popular model VT003F, which has been widely accepted by thousands of users for its quality and effectiveness. VT007 comes with further improved quality, performance and usability, and produces much less mechanical noise.
The major re-engineering initiatives of VT007 are 1) reduction of number of parts and 2) separation of the control box from the vibrating machine body.
The separated control box is made entirely by our specialty EMS factory for more reliable testing and quality control processes.
VT007 has an industrial style design. It is robust, durable, and reliable. Its open style makes service easier if needed.
VT007 is probably the best home-use linear vibration plate ever made.
