Studies have shown that a minute, noise-like electrical stimulation (ES) of a
lower limb joint stabilizes one-legged standing (OS), possibly due to the
noise-enhanced joint proprioception. To demonstrate the practical utility of this
finding, we assessed whether the bipedal stance (BS), relatively stable and
generally employed in daily activities, is also stabilized by the same ES method.
Twelve volunteers maintained quiet BS with or without an unperceivable,
noise-like ES of a knee joint.
The results showed that the average amplitude,
peak-to-peak amplitude, and standard deviation of the foot center of pressure in
the anteroposterior direction were significantly attenuated by the ES (P<0.05).
These results indicate that the BS also can be stabilized by an unperceivable,
noise-like ES of a knee joint.
