While clinical assessment of locomotor function in this population is carried out using tasks involving walking in a straight line without any obstacles, it does not take into account ecological situations (i.e., situations comparable to real-life situations) in which the person interacts with their environment, such as walking down a street with other pedestrians, which is fundamental to everyday life. This research therefore aims to study the social navigation skills during locomotion of people who have suffered a moderate or severe head injury in the chronic phase in more ecological tasks. This will provide a better understanding of the difficulties encountered by these patients during locomotor interactions in everyday life.
18 ≤ Age ≤ 55 years old
Male/female
Having suffered a first non-penetrating head injury
Moderate to severe severity with initial Glasgow Coma Scale score 5<GCS<13
Severe patho-psychiatric care underway, which may impact the conduct of the protocol, at the investigator's discretion
Presence of neurological signs suggestive of a neurodegenerative disease responsible for gait disturbance (Parkinson's syndrome, Alzheimer's disease, etc.)
Individuals with musculoskeletal disorders that impact their locomotor abilities
Presence of uncontrolled epilepsy at the time of inclusion
Single group
Locomotion in a virtual reality setting
Other interventionPatients and participants will be asked to perform several walking/locomotion tasks in a virtual evironment setting. The setting in question is a concert in a parc. The participants will have to walk towards the stage whilst avoiding bumping into "virtual people". A total of 5 different tasks (walking in a straight line, walking between people etc) will be completed for each participant. Different variables will then be recorded and extracted such as walking speed, interpersonnal distances, eye fixation times.
Perceptive dimension : Elements of the environment viewed : Distribution (in %)
Perceptive dimension : Elements of the environment viewed : Distance (in meters)
Perceptive dimension : Elements of the environment viewed : duration of fixations (in milliseconds)
Cognitive dimension : characteristics of the path taken : length of the path taken (in meters)

Balance test : ABC-scale
Balance test : "Berg Balance Scale" (BBS)
Balance test: Berg Balance Scale (BBS), 14-item scale with a total score ranging from 0 (worst balance) to 56 (best balance); higher scores indicate better balance.
