Detaljeret beskrivelse
This is a single-blind, open-label pilot study to evaluate the feasibility and preliminary efficacy of remotely supervised, at-home delivery of tVNS in individuals with moderate to severe TBI during the post-acute recovery phase.
Eligible participants will complete a 2-week tVNS intervention protocol at home.
Mixed methods (quantitative and qualitative) will be used to evaluate outcomes.
Eligible participants will be invited to initial baseline assessment and tVNS training session (Visit 1).
Then, they will complete two weeks of at-home administration period.
Lastly, they will return to a post- stimulation assessment (Visit 2).
In the assessment sessions participants will complete tasks of set shifting and working memory, core executive functions, as well as complete surveys regarding fatigue, sleep, and overall quality of life.

N-Back task
Tidsramme: Day 0 Baseline and Day 15 Post Stimulation Assessment
|
In the N-Back Task, participants are presented a series of visual stimuli.
They are asking for each stimulus whether is matches a stimulus n-trials before.
For example, in a 2-back task, in which the trials consist of letters, participants have to decide whether the current letter is the same as the letter in the trial n-2.
We will use a computerized version of this task.

California Verbal Learning Test
Tidsramme: Day 0 Baseline and Day 15 Post Stimulation Assessment
|
The California Verbal Learning Test evaluates the ability to encode, recall, and recognize verbally presented information across multiple learning trials and delayed recall conditions.
Participants are read multiple lists of words and asked to recall specific words at different time allotments.

Day 0 Baseline and Day 15 Post Stimulation Assessment
|
|
Trail Making Test A&B
Tidsramme: Day 0 Baseline and Day 15 Post Stimulation Assessment
|
Trail Making Part A requires participant to draw a line between circles containing numbers in ascending order.
Part B requires participants to alternate drawing a line between ascending letters and numbers.
The key measures are the time required to complete and the number of errors made in Part A and Part B. The test measures various aspects of cognition including attention, visual search, motor coordination, reasoning, and task switching.
