Muscular Synergies and Behavioral Adaptations of Gait in Pain Anticipation (SYAMAPP)
Sponsor: Universite de Picardie Jules Verne
Summary
The purpose of this study is to determine whether the anticipation of pain influences gait control and psychophysiological responses in healthy individuals. Participants will receive a neutral cream described either as potentially painful (experimental group) or inert (control group), and their behavioral and physiological adaptations will be measured during walking tasks.

Conditions
Interventions
Pain expectation conditioning
Participants receive application of a neutral cream (MEDICAFARM) with verbal and behavioral suggestions that it may cause localized pain. Researchers wear gloves during application and emphasize potential discomfort, stating effects may intensify with movement.
Comparator (Control Group)
Participants receive identical application of the neutral cream but are informed it is inert and harmless. Researchers apply the cream without gloves and provide neutral instructions.
Intervention: Gait
Participants undergo assessment procedures including: * Pre- and post-application gait analysis (GAITRite mat, Zebris treadmill) * Physiological monitoring (EMG, HRV, EDA) * Identical questionnaires (BPI, TSK, FACS, PCS, VAS)
