why pulsed vibrations are so effective Vibrating shoes have been shown to be useful for helping elderly populations avoid falls; their diminished sensory acuity makes it hard for them to feel the differential pressure which indicates that they are starting to fall, but adding noise results in the sensory threshold being crossed. I'd presume that the muscle overstimulation which causes characteristic twitching/jerking is being suppressed by improved sensation of pressure.
