Although there are several commercial-grade and consumer-grade models of Whole Body Vibration equipment on the market, they vary widely in their function and intended applications. Following is a guide to understanding the key variables.
Style for Life exclusively offers mid-frequency, variable-amplitude WBV based on the center fulcrum model. This combination is the safest, most comfortable and most effective vibration suitable for both fitness and geriatric/rehab applications.
In addition, our equipment features:

Variable Options Purpose Comments Frequency(speed of vibration)
The greater the speed, the more force applied to the muscle fibers.

• High Frequency
  (30-60Hz) Intended for athletic training; too intense for geriatrics and spinal rehab Repeated exposure to high-frequency vibration has been shown to cause spine and joint damage
• Mid Frequency
  (15- 40 Hz.) Ideal range for both athletic training and geriatrics/spinal rehab Ideal range for both athletic training and geriatrics/spinal rehab

Amplitude
(high-low range of platform motion)
Lower amplitudes apply less force to the muscle fibers; greater amplitudes apply greater force (combined with frequency and body mass). Low Amplitude better for geriatrics and spinal rehab Better for geriatrics and spinal rehab; less effective for fitness/athletics. Variable amplitude delivers best of both worlds.

• High Amplitude
  Better for fitness/athletic purposes.
  Good for fitness/athletic training; too intense for geriatrics and spinal rehab.
• Vibration Style
  (direction of motion in the platform)
• Unidirectional
  Platform is based on a center fulcrum (like a see-saw), creating left/right up/down motion. This pattern allows for the stabilization of the spine and head, due to the left-right, natural tilting action of the pelvis, which resembles walking. Ability to vary amplitude simply by positioning feet closer to the center or the sides of the platform
• Tri-Planar
  (aka "Vertical") Platform moves in three directions: up/down (vertical), left/right and back/forth. Vertical motion applies another degree of force to the muscle fibers. Many researchers have expressed concerns about spinal compression with vertical vibration. Tri-planar motion creates a "shaking" sensation that causes dizziness and nausea in many users
