The following is a written answer from Professor Clinton Rubin to a question asked by a prospective Marodyne LiV user:
“Thank you for your question regarding the safety of Low-intensity Vibration therapy. There are a few ways to answer that, all circling back to the same point – it is safe.”
“First, the ‘transmissibility’; this is the percentage of vibration delivered to the bottom of your foot versus the different regions of your body.”
“0.4g, the intensity of the Marodyne, at 30Hz delivers approximately 80% of signal to the hip and 75% is efficiently transmitted to the spine (about 0.3g). This is because the signal attenuates (or lessens) as it travels up your body, due to absorption from body tissues.”
“By the time the signal reaches your head, less than 0.1g can be measured with an accelerometer – a device that measures vibration.”
“These signals are far less than the vibration on your skull when you drive a car or even go on a walk. So the signal is very low, but can still be felt.”
“Secondly, in ALL clinical trials we have run, all of which have been reviewed and approved for safety by a university of hospital internal review board, and then follow up reports to the data safety monitoring board, we have NEVER had a serious adverse event reported, and no reports regarding the eye or irritation to it.”
“There have been reports of detached retinas, hearing loss and back pain from people standing on HIGH-intensity vibration devices with a magnitude of 7g and above, but this is way beyond the signal delivered by the Marodyne LiV device.”
“So the bottom line – you are safe – and with all the trials we have run, we have never experienced any issues with the eye.”
