Sample entropy of postural acceleration

1. Surface instability decreases sample entropy of postural acceleration in humans.

   “Increased surface instability also progressively decreases SampEn in the mediolateral direction (p < 0.001), reflecting less automaticity with increased instability.”

More on Surface instability

1. Middle age is associated with sample entropy of postural acceleration in humans.

   “Young adults exhibit more irregular fluctuations in postural acceleration (high SampEn), reflecting greater efficiency or automaticity in postural control compared to middle-aged adults.”
