Segmental Exclusion of the Upper Limb and Peri-personal Space

This study is based on previous studies on the search of the limit of the peri-personal space. In a previous study, Gouzien et al. (2017) evaluated the peri-personal space of action of patients with upper limb amputations and sought a link between this space and the level of integration of their myoelectric prosthesis. We have decided to implement part of this protocol to evaluate the peri-personal space for another population with upper limb patholog: segmental exclusion of the upper limb. Exclusion is a phenomenon that is very little studied but known to orthopedic surgeons and physical medicine and rehabilitation physicians. It is characterized by the non-use or underuse of a limb segment in the absence of central nervous system involvement. This phenomenon is compared to peripheral neglect. Most of the time, the patient is unaware of his disorder "he forgets his finger without realizing it", but this phenomenon can be reversible under verbal exhortation from a third party. The aim of this study is to observe if there is a change in peri-personal space in patients with unilateral segmental exclusion.
