From: Quantifying dimensions of physical behavior in chronic pain conditions
Variation of metrics between groups of subjects with chronic pain caused by spinal stenosis (SS), failed back surgery syndrome (FBSS) and complex regional pain syndrome (CRPS). Lower entropy values for CRPS patients indicate a reduced diversity of body movements/activities, low movement intensity and long sedentary periods, suggesting the potential of this metric to capture clinically recognized motor-impairements
