Implementing New Technologies to Improve Visual-Spatial Functions in Patients with Impaired Consciousness

Area of Science:

• Neuroscience
• Ophthalmology
• Rehabilitation Medicine

Background:

• Severe brain damage significantly impairs patients' quality of life, affecting cognitive and ocular functions.
• Non-communicative patients with brain damage present unique challenges in therapeutic interventions.

Purpose of the Study:

• To investigate the effectiveness of oculomotor training for improving visual-spatial functions in non-communicative patients with severe brain damage.
• To assess the impact of eye-tracker-based therapeutic tasks on cognitive and ocular dysfunction.

Main Methods:

• A six-week oculomotor training program was implemented for five male patients with severe brain damage.
• Participants engaged in eye-tracker-guided tasks focusing on object recognition, size and color perception, and image assembly.
• Tasks included perceiving object structures (letters and objects), detecting image differences, and assembling image components.

Main Results:

• The study demonstrated positive outcomes from the oculomotor training intervention.
• Improved visual-spatial functions were observed in the participants following the training period.
• Extended engagement with eye-tracker technology correlated with enhanced functional improvements.

Conclusions:

• Oculomotor training, particularly when utilizing eye-tracker technology over extended periods, is effective in enhancing visual-spatial functions.
• This therapeutic approach offers a promising avenue for improving the quality of life for non-communicative patients with severe brain damage.
