Traumatic Brain Injury
Conditions
Brief summary
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.
Interventions
Patients 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.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Perceptive dimension : Elements of the environment viewed : Distribution (in %) | From enrollment to the end of the participation at maximum 30 days |
| Perceptive dimension : Elements of the environment viewed : Distance (in meters) | From enrollment to the end of the participation at maximum 30 days |
| Perceptive dimension : Elements of the environment viewed : duration of fixations (in milliseconds) | From enrollment to the end of the participation at maximum 30 days |
| Cognitive dimension : characteristics of the path taken : length of the path taken (in meters) | From enrollment to the end of the participation at maximum 30 days |
| Cognitive dimension : characteristics of the path taken : interpersonal distances with virtual humans (in m) | From enrollment to the end of the participation at maximum 30 days |
| Action-related dimension : walking speed (measured in m/s) | From enrollment to the end of the participation at maximum 30 days |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| " Montréal Cognitive Assesment " (MoCA) | On day 1 | — |
| " 10-Meter Walking Test " (10MWT) | At day 1 | — |
| Balance test : ABC-scale | At day 1 | — |
| Balance test : "Berg Balance Scale" (BBS) | At day 1 | 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. |
| Balance test : "Time Up and Go" (TUG) | At day 1 | Balance test: Timed Up and Go (TUG), time to complete the test measured in seconds; lower times indicate better functional mobility and balance, whereas longer times indicate poorer mobility and increased fall risk. |
