About this trial

The aim of this phase is to examine the feasibility and acceptability of the Augmented Reality (AR)-based and electroencephalography (EEG)-based neglect detection and rehabilitation tool.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

ages18 and older

acute stroke

admitted to inpatient rehabilitation

presence of neglect (Behavioral Inattention Test total score <129, or scoring below pre-defined cutoff score in at least one of the six subtests)

Disqualifiers

inability to follow one-step directions at least 80% of the time

current diagnosis of dementia, Parkinson's disease, multiple sclerosis, or space-occupying tumor

metal in the head that causes interference with the EEG system

self-report of previous positive photic stimulation test

Trial design

Design model

Single group

Treatments tested in this trial

  • augmented reality

    Behavioral

    The participants will be wearing an EEG cap and Augmented Reality headset (AR-based EEG-guided system) for 10 sessions with a licensed occupational therapist, provided in addition to usual rehabilitation care (either in inpatient rehabilitation or at home). These sessions will focus on activities of daily living that the participants want to practice. All sessions will last approximately 1 hour. These sessions will be scheduled around the existing therapy schedule to cause the least amount of interference with planned clinical activities.

Trial outcomes

Primary outcomes

1

Accuracy; indicated by percent agreement between participant report and EEG-based assessment of neglect

number of sessions attaining greater than 70 percentage agreement between targets identified by the participant and targets identified by EEG; participants view an augmented reality screen with randomly appearing targets in the field of view; when a target is viewed, the participant presses a keyboard key; immediately after, targets randomly appear on the augmented reality screen while the participant's brain activity is recorded by EEG; EEG detects viewed and neglected targets based on brain signals;

Time frame
week 4
2

Reliability; indicated by correlation coefficient between two consecutive sessions of EEG recording

number of consecutive sessions attaining Pearson correlation coefficient r greater than.10

Time frame
week 4

Secondary outcomes

1

Technology Satisfaction; indicated by a mean score of 3 or higher on the Quebec User Evaluation of Satisfaction with Assistive Technology

number of participants attaining greater than or equal to 90 percentage satisfaction; satisfaction is rated on 12 items with a 5-point likert scale, 5 indicating very high satisfaction; items are summed with total a total score of 60 indicating very high satisfaction;

Time frame
week 4
2

Program Satisfaction; indicated by mean score of 3 or greater on the Client Satisfaction Questionnaire

number of participants attaining greater than or equal to 90 percentage satisfaction; satisfaction is rated on 8 items with a 4-point likert scale, 4 indicating very high satisfaction; items are summed with total a total score of 32 indicating very high satisfaction;
