Segmental Exclusion of the Upper Limb and Peri-personal Space (EPPEX)

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.

Study Population

The patients included in this study are patients with upper extremity musculoskeletal disorders of traumatic origin. To these disorders is added a segmental exclusion syndrome, which is defined as the under-use or non-use of part of the upper limb.

Inclusion Criteria:

• Adult (age greater than or equal to 18 years old).
• Person with a symptom of unilateral exclusion.
• Person with no contraindication to hard work in activities of daily living due to the lesions.
• Person who has given informed consent.

Exclusion Criteria:

• Person under 18 years of age.
• Person with visual impairment
• A person with a central neurological pathology.
• A person with cognitive impairment related to a brain injury, psychiatric illness or intellectual disability.
• A person who has difficulty understanding instructions.
• A person of full age who is subject to a legal protection measure or who is unable to give consent.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Control	Other: Measurement of the actual and perceived maximum reachable distance; A device (a table) will present luminous targets (green circles) to the subjects. Subjects will be asked to determine whether or not they are able to reach this target with their upper limb.
Patients with exclusion	Other: Measurement of the actual and perceived maximum reachable distance; A device (a table) will present luminous targets (green circles) to the subjects. Subjects will be asked to determine whether or not they are able to reach this target with their upper limb.
