Galileo (vibration training)
Galileo (in the US also available as ''Vibraflex'') is a brand of vibration training platforms used as exercise equipment as well as for therapeutic use. It consists of a vibration platform which vibrates sinusoidal side alternating like a see-saw. Depending on the device size it oscillates with an amplitude of up to 6 mm (equivalent to a peak to peak distance of 12 mm) and a frequency of 5 Hz to 30 Hz (5 to 30 repetitions per second). Due to its high amplitudes and vibration frequencies above 12 Hz it is able to utilize stretch reflexes. Galileo is manufactured in Germany by the German company Novotec Medical GmbH. Since 2004 Galileo is also available as a medical device.
==Basic Function==
The base plate of Galileo vibration training devices is moving like a see-saw. This side alternating motion is supposed to mimic human gait in order to utilize nearly physiological motion patterns close to the side alternating human gait. The side alternation causes the hip to tilt which requires the contra lateral muscles of the back to be activated – while one leg is lifted the other drops. Compared to vertically vibrating devices the side alternating motion results in very low acceleration acting on the centre of gravity of the upper body and the head.
