Post-doctorate researcher 

(FNRS clinicien chercheur post-doctorant)

Coordinator: Pr. A. Mouraux

The topic of my postdoctorate research fellowship is to examine interactions between pain and visuospatial perception in patients with unilateral chronic pain. As a clinical researcher, my aim is to assess the efficacy of prism adaptation as an original non-pharmacological approach to alleviate pain and to improve the functional outcome in patients with unilateral chronic pain of the upper extremity.
