Implicit Motor Imagery for Chronic Pelvic Pain: A Cross-Sectional Case-Control Study

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Psychology

Background:

• Chronic pelvic pain (CPP) impacts body schema perception.
• Implicit motor imagery (IMI) is a potential therapeutic approach for CPP.
• Understanding differences between CPP patients and healthy individuals is crucial for IMI's application.

Purpose of the Study:

• To analyze differences in a laterality discrimination (LD) task between CPP patients and healthy controls.
• To provide evidence supporting the use of IMI in CPP therapy.
• To investigate correlations between pain, psychological factors, and task performance.

Main Methods:

• Observational, cross-sectional, case-control study.
• 130 participants (64 CPP patients, 66 healthy controls) completed an online LD task with abdominoperineal images.
• Outcome measures included pain intensity (VAS), accuracy, response time (RT), and CPPQ-Mohedo score.

Main Results:

• Significant differences observed in accuracy, CPPQ-Mohedo, and VAS between groups (p < 0.001).
• CPP patients exhibited lower accuracy in the LD task compared to controls.
• Higher pain intensity correlated with higher CPPQ-Mohedo scores, longer RT, and lower accuracy in CPP patients.

Conclusions:

• Patients with CPP demonstrate distinct performance patterns in the LD task.
• IMI shows promise as a complementary therapeutic tool for CPP.
• The findings support the rationale for using IMI to address body schema issues in CPP.
