Video game training in traumatic brain injury patients: an exploratory case report study using eye tracking

Area of Science:

• Neuroscience
• Cognitive Rehabilitation
• Human-Computer Interaction

Background:

• Attentional impairments are a significant challenge in cognitive rehabilitation following traumatic brain injury (TBI).
• Previous research indicates that action video games can enhance attention in healthy individuals.
• The potential of video games for cognitive training in TBI populations remains largely unexplored.

Purpose of the Study:

• To investigate the efficacy of action video game training for remediating attentional deficits in severe TBI participants.
• To assess changes in visual attention using saccadic eye movements as objective indicators.
• To evaluate the impact of a 10-hour action video game intervention.

Main Methods:

• Employed a multiple baseline single-case experimental design (SCED) with three severe TBI participants.
• Assessed saccadic eye movements during self-paced saccade and abstract visual search tasks.
• Measured performance across baseline, mid-training, and post-training phases, analyzing data using Percentage of Non-overlapping Data (PND).

Main Results:

• Significant increases in self-paced saccade rates were observed in two participants (PND=80%, PND=70%).
• Improvements in abstract visual search included reduced fixation duration (Participant 2: PND=60%, Participant 3: PND=80%) and search time (Participant 2: PND=100%, Participant 3: PND=70%).
• These findings suggest potential modifications in attentional allocation during eye movements.

Conclusions:

• Action video game training shows promise as a novel cognitive training method for TBI.
• Observed improvements in saccadic eye movements indicate potential benefits for visual attention.
• Further research is necessary to confirm the effectiveness and clinical utility of this intervention.
