BACKGROUND: The peripheral deafferentation induced by regional anaesthesia (RA) results in misperception of size-shape (S) and posture (P) of the anesthetized limb. During RA, most patients seem to describe motionless 'phantom limbs' fixed in stereotyped illusory positions, suggesting that RA could unmask stable postural patterns. The question of whether movement ...
