Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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
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.
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
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.
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
Motor imagery Questionnaire - Revised Second (MIQ-RS)
