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.

Pilot Study on the Assessment of Motor Imaging Skills in Patients With Complex Regional Pain Syndrome (CRPS)

Summary

Medical functional imagery seems to demonstrate that patients suffering from complex regional pain syndrome (CRPS) have cortical modifications that alter their motor (or mental) imagery capacities. Nowadays, the use of motor imagery exercises are used in conventional rehabilitation treatments. But, in clinical practice, no study has verified if patients with CRPS desmonstrate problems in their motor imagery capacities. The MIQ-RS (Motor Imagery Questionnaire - Revised Second) is a valid, reliable and translated into French questionnaire to measure patients' capacities to do mental imagery. In this study, we compare 3 groups of 50 patients : healthy patients, patients with CRPS and patients with musculoskeletal disorder without CRPS. Every patient will take the MIQ-RS for the right and left body side. We hypothesis that patients with CRPS have more deficit than the 2 others to realise motor imagery.

Type	Name	Description
DIAGNOSTIC_TEST	Motor imagery Questionnaire - Revised Second (MIQ-RS)	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.
