Summary

Brain injuries may cause the loss of the ability to see portions of the visual field, the so-called visual field defects (VFDs). VFDs significantly impact the survivors' functional recovery and quality of life, with the majority of patients displaying no spontaneous recovery or being left with residual deficits. Among the available therapies for VFDs, the compensatory scanning training is considered the most promising. Yet, current evidence is insufficient to recommend it in clinical practice, and the scientific community has stressed the need of more high-quality research. The present randomized clinical trial in patients with chronic VFDs caused by brain lesions aims at verifying the feasibility and efficacy of a novel telerehabilitation using a multisensory scanning therapy, by measuring its effects on visual functions and daily activities, and by looking for neural indicators of the therapy-induced improvements.

Interventions

BEHAVIORAL

Audio-visual training (AVT) telerehabilitation

Participants are trained at home, with remote supervision, for 3 weeks (5 days/week, 2 hours/day) using an audio-visual device suitable for telerehabilitation (AVDESK, Linari Medical). Specifically, visual stimuli (LEDs) appear on a semicircular panel, either alone or paired with an acoustic cues, at different eccentricities. Stimuli to the blind visual field (70%) and intact visual field (30%) are presented in random sequence. Patients are trained to scan the visual field by shifting their gaze (from the central fixation point) towards the visual target (with or without sounds), without head movements, and to report its presence by pressing the response key.
