The Complex Regional Pain Syndrome (CRPS) is a Chronic Pain Condition. This is a Preliminary Study to Explore and Test Clinical Hypothesis. They Suppose That CRPS Patients Have Impairment in Their Mental or Motor Imagery Abilities.

"Patients fulfill a questionnaire measuring individuals capacities to realize mental imagery. For more facilities and less risk of bias, the MIQ-RS was written on an online version with questions recorded in audio format. No official cut-off exists but studies seem to prove that people with :~* a score less than 48/98 are unable to do motor imagery~* a score between 49 and 73/98 have disturbed motor imagery capacities~* a score more than 74/98 have normal motor imagery capacities."
