I saw an older gentleman using a Bodyblade at the P.T. clinic where I go for back treatment. He made it look so easy, but when I tried it, I just couldn't get the right rhythm. What the trick?
It appears that some people are more naturally adept at using the Bodyblade. Others, like yourself, find it difficult, if not impossible, to master. Even some highly skilled athletes are unable to work with the Bodyblade.
The Bodyblade is a thin foil or sword-like instrument held in one or two hands. By using just the right amount of arm and trunk motion, the foil oscillates (moves back and forth) at a natural frequency of 4.5 Hz. Too much arm or trunk motion will interfere with the oscillations.
The blade must be held at just the right angle. Motion of the hand must be in the plane perpendicular to the length and flat side of the blade. Any extra motion in other directions will effect the blade resonance.
Exactly why there are such wide differences between users remains a mystery. For those who master it quickly and easily, it can be a valuable tool in spine rehab. Regular use of this device can help improve strength, balance, and coordination needed for spinal stability.
For others, the improper use of the Bodyblade can actually increase compressive forces making this a potentially unsafe treatment method.
