Virtual reality-based attention training in patients with neurological damage: A pilot study

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Human-Computer Interaction

Background:

• Virtual Reality (VR) is a validated tool for ecologically valid cognitive function assessment.
• Evidence for VR's effectiveness in cognitive rehabilitation and real-world transfer is limited.
• Attentional deficits are common in neurological disorders, impacting daily functioning.

Purpose of the Study:

• To evaluate the efficacy of VR-based attention training for neurological patients.
• To assess the transfer of VR attention training effects to everyday life functioning.
• To investigate changes in subjective attentional functioning post-VR intervention.

Main Methods:

• Nineteen inpatients with neurological disorders and attentional deficits participated.
• Daily 30-minute VR attention training sessions were conducted over two weeks.
• Attentional functions were assessed pre- and post-training using computerized tests, behavioral tasks, and a subjective questionnaire.

Main Results:

• Significant improvements were observed in reaction times for computerized alertness and selective attention tests.
• No significant transfer of training effects was found for behavioral tasks or self-reported attentional functioning.
• Improvements were specific to neuropsychological measures, with potential confounding effects due to the absence of a control group.

Conclusions:

• VR-based attention training shows potential for improving specific attentional functions measured by neuropsychological tests in neurological patients.
• The training did not demonstrate transfer to ecologically valid tasks or subjective improvements in daily life functioning.
• Future VR interventions require further development to enhance real-world transferability and clinical utility.
