Investigation into the oscillatory behaviour of the spinal column under whole body vibration.

Studies are under way to look at the effects of vibration under spinal load. Studies have shown that static load can be identified by measuring changes of stature, but when the spine is vibrated changes of stature do not show the same simple relationship to estimated load. It is deduced that the spine may be oscillating in a complex way which introduces nodes at different points along its wave length.
