Juvent platform for dynamic motion therapy-

using a platform that looks like bathroom scales, Juvent “adjusts” and tunes itself during the first 12 seconds, then delivers oscillations between 32 and 37 Hz at a low gravitational force of 0.3g for 20 minutes while the patient stands on the platform.  The manufacturer touts this as improving bone health, reducing joint pain, increasing muscle strength, enhancing sense of balance, increasing red blood cell and stem cell production, and helps prevent osteoporosis .  The device is bought online for $3,495.  No studies are listed on the website although the site alludes to “scientifically proven”.  It is investigational in the US as approved by the FDA.   Most of the studies show no effect whatsoever in running economy and vertical stiffness (J Strength Cond Res 2015 Jan 25), any increase in bone density Z-scores {J Rehabil Med 2015 Feb23;47(3):223-8,  J Bone Miner Res 2015 Jan 8,   },  gait function (J Neurol Sci 2014 Dec 15:347(1-2):119-23), performance recovery (Int J Sports Physiol Perform 2014 Sept 17),  improvement in knee pain from osteoarthritis (Clin Rehabil 2014, Dec 18).  The treatment does result in small improvements in back pain (24%) and even smaller improvements in function (9% Roland Morris) in non specific back pain treatment (J Rehab Med 2011 Jul;43(8):689-94) The website is www.juvent.com

Painbytes assessment: one thumb down.  There are not enough positive studies or studies with clinically meaningful improvement to recommend this therapy.  There are very few safety issues with the therapy.
