Background: Complex regional pain syndrome (CRPS) is associated with deficits in limb recognition. The purpose of our study was to determine whether mental load during this task affected performance, sympathetic nervous system activity or pain in CRPS patients.
Methods: We investigated twenty CRPS-I patients with pain in the upper extremity and twenty age- and sex-matched healthy controls.
The aim of this study was to compare the satisfaction and success of treatment for pain patients who were interdisciplinary (anaesthesiological, psychosomatic, neurological, orthopedic) treated or underwent neurological care alone. We selected 183 patients who were treated in our neurological clinic and in our interdisciplinary pain management center (IST). Of these, 142 patients having polyneuropathy, headache or muskuloskelettal pain were included in the final analysis.

Methods: Sixteen healthy subjects (8 males, mean age 27 ± 5 years) were included in a first set of experiments consisting of three visits: (1) Visit: Quantitative sensory testing (QST) was performed before and after intradermal capsaicin injection (CAPS, 15 μg) on one thigh and electrical current stimulation (ES, 1 Hz) on the contralateral thigh.
Being able to remember physically and emotionally painful events in one's own past may shape behavior, and can create an aversion to a variety of situations. Pain imagination is a related process that may include recall of past experiences, in addition to production of sensory and emotional percepts without external stimuli. This study aimed to understand 1) the central nervous system processes that underlie pain imagination, 2) the retrieval of pain memories, and 3) to compare the latter with visual object memory.
