In complex regional pain syndrome (CRPS), sensory deficits and/or hyperalgesia often extend beyond the affected limb to encompass other sites on the ipsilateral side of the body. The aim of this study was to determine whether hyperalgesia in the ipsilateral forehead reflects disinhibition and/or sensitization of trigeminal afferent or second-order neurons on the CRPS-affected side.
