Effect of Eye-Tracking Technology-Based Visual Scanning Training on Unilateral Spatial Neglect after Stroke

Area of Science:

• Neurology
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Unilateral spatial neglect (USN) is a common and disabling consequence of stroke.
• Effective rehabilitation strategies for USN are crucial for improving patient outcomes.
• Eye-tracking technology offers a novel approach to visual scanning training.

Purpose of the Study:

• To investigate the efficacy of eye-tracking technology-based visual scanning training for USN recovery.
• To compare the effects of eye-tracking training with conventional visual scanning training.
• To assess the impact on USN severity, activities of daily living (ADLs), and cognitive function.

Main Methods:

• A randomized controlled trial involving 48 stroke patients with USN.
• Experimental group: 15 min eye-tracking training + 15 min conventional training.
• Control group: 30 min conventional training. Assessments included BIT-C, CBS, MBI, and MMSE.

Main Results:

• Eye-tracking training significantly alleviated USN and reduced neglect severity in ADLs.
• No significant differences were observed in ADL or Mini-Mental State Examination (MMSE) scores between groups.
• Both groups received standard care, including drug therapy and occupational rehabilitation.

Conclusions:

• Eye-tracking technology-based visual scanning training shows promise in targeting USN symptoms.
• Further research may be needed to enhance its impact on overall functional independence and cognitive recovery.
• This technology presents a potential advancement in stroke rehabilitation for visual neglect.
