Is successful rehabilitation of complex regional pain syndrome due to sustained attention to the affected limb ? A randomised clinical trial . In complex regional pain syndrome ( CRPS1 ) initiated by wrist fracture , a motor imagery program ( MIP ) , consisting of hand laterality recognition followed by imagined movements and then mirror movements , reduces pain and disability , but the mechanism of effect is unclear . Possibilities include sustained attention to the affected limb , in which case the order of MIP components would not alter the effect , and sequential activation of cortical motor networks , in which case it would . Twenty subjects with chronic CRPS1 initiated by wrist fracture and who satisfied stringent inclusion criteria , were randomly allocated to one of three groups : hand laterality recognition , imagined movements , mirror movements ( RecImMir , MIP ) ; imagined movements , recognition , imagined movements ( ImRecIm ) ; recognition , mirror movements , recognition ( RecMirRec ) . At 6 and 18 weeks , reduced pain and disability were greater for the RecImMir group than for the other groups ( P < 0.05 ) . Hand laterality recognition imparted a consistent reduction in pain and disability across groups , however , this effect was limited in magnitude . Imagined movements imparted a further reduction in pain and disability , but only if they followed hand laterality recognition . Mirror movements also imparted a reduction in pain and disability , but only when they followed imagined movements . The effect of the MIP seems to be dependent on the order of components , which suggests that it is not due to sustained attention to the affected limb , but is consistent with sequential activation of cortical motor networks .
