Peripersonal Space Representation in Upper Limb Segmental Exclusion

NCT07349173 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 60

No results posted yet for this study

Summary

This study aims to evaluate the representation of action peripersonal space (PPS) in subjects suffering from unilateral segmental exclusion syndrome of the upper limb compared to healthy control subjects. Segmental exclusion is defined by non-use or under-use of a limb segment without central nervous system damage. The study hypothesizes that this syndrome leads to a modification (shrinkage) of the PPS representation. Participants will perform reachability judgments in a Virtual Reality (VR) environment.

Conditions

  • Segmental Exclusion Syndrome
  • Complex Regional Pain Syndrome (CRPS)
  • Upper Limb Neglect (Peripheral)

Interventions

BEHAVIORAL

Reachability Judgment Task in VR.

Participants wear an Oculus Quest 2 VR headset. They first perform a motor task to measure Real Reachable Distance (DMA-r). Then, they perform a perceptual task where they must judge, without moving, if a virtual object is reachable (DMA-p). The test evaluates different spatial planes (front, 45° right, 45° left) and heights (shoulder, navel).
