Muscle Synergies in Pain and Pain Anticipation

Test-retest Fidelity of a Tool for Calculation of Muscle Synergies

Sponsor

Universite de Picardie Jules Verne

Enrollment

12 participants

Start Date

Jan 1, 2026

Study Type

INTERVENTIONAL

Conditions

Nocebo effect Pain Pain Anticipation

Summary

This study investigates how the anticipation of pain affects muscle synergies. One group will be recruited who will first experience actual pain from capsaicin cream and are then presented with a harmless cream deceptively labeled as capsaicin. The changes in muscle synergies will be measured during walking tasks.

Eligibility

Min Age: 18 YearsMax Age: 35 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying Gait assesment and Pain expectation conditioning for people with nocebo effect, pain, and other related conditions. The study is currently recruiting participants at 2 locations. People eligible for this study include aged 18 Years to 35 Years.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.

Interventions

OTHERPain expectation conditioning

Participants receive a neutral cream with no real harmful effects with verbal and behavioral suggestions that it may cause localized pain. Researchers wear gloves during application and emphasize the potential discomfort, stating effects may intensify with movement.

OTHERGait assesment

Gait will be assessed both before and after cream application. Each assessment will consist of walking on a treadmill at varying speeds while physiological data (EMG) is recorded. Identical questionnaires (VAS, TAMPA, and PCS) will be administered immediately following the first gait assessment.
