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. (ImagNimes)

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

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.

Design Details

  • Primary Purpose: Screening
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Healthy patients
Healthy patients take the MIQ-RS during about 40 minutes : about 20 minutes for the assessment of the right side and about 20 minutes for the left side
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.
Other: Complex regional pain syndrome patients
Complex regional pain syndrome patients take the MIQ-RS during about 40 minutes : about 20 minutes for the assessment of the right side and about 20 minutes for the left side
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.
Other: Musculoskelettal disorders patients
Musculoskelettal disorders patients take the MIQ-RS during about 40 minutes : about 20 minutes for the assessment of the right side and about 20 minutes for the left side
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

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Motor imagery capacities on the affected side for CRPS group and musculoskelettal disorder group.
Time Frame: Day 1

Taking the MIQ-RS for 1 side, during about 20 minutes The questionnaire includes 14 questions : 7 for kinesthesic motor imagery and 7 for visual motor imagery For less bias, the questionnaire was recorded in audio for each of the 14 questions on an online assessment.

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.
Day 1
