Not yet recruiting. Open to participants aged 18 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-01-05.

In this study, the investigators will use a wearable device capable of performing this bedside assessment to evaluate the incidence of visual field loss in post-stroke patients. Furthermore, for those with visual field loss, the investigators will investigate whether integrating multisensory audio-visual rehabilitation into the standard physical rehabilitation protocol can help improve visual field loss compared to standard rehabilitation alone.
The objectives of the research are:
The research is planned to be conducted in Genova Italy and to include 300 patients.
In this study, the investigators will recruit acute post-stroke patients from the Neurology Unit of IRCCS Policlinico San Martino hospital. The study will use a wearable device (PalmScan VF2000) to assess the visual field defects. Those with significant visual field defects will be randomly assigned to either the visual rehabilitation group, receiving visual rehabilitation treatment integrated into their physical rehabilitation protocol, or the standard group. Inclusion criteria include: age between 18 and 90 years, post-stroke patients (excluding isolated cerebellar, brainstem, or spinal cord strokes), admitted to the Neurology Unit of the IRCCS Policlinico San Martino hospital, able to understand and sign the informed consent for study participation, and having mobility in at least one upper limb. Exclusion criteria include: cognitive impairment that limits understanding of the informed consent or testing, difficulty with both upper limb movements, presence of ocular comorbidity that could affect pre-ictal visual field assessment, presence of fluid aphasia, neglect or deviation of the head and gaze, impaired consciousness or delirium. Baseline assessments will be conducted at the Neurology Unit of the IRCCS Policlinico San Martino hospital.
After the baseline assessment, all participants diagnosed with visual field impairment will be assigned to the David Chiossone Foundation, with the option of being referred to a post-acute residential facility or undergoing outpatient treatment. Otherwise, patients requiring intensive care will be referred to another competent local center.
Participants will be randomly divided into two groups:
After 8 weeks since they are dismissed by the hospital Neurology Unit, all patients (even those not receiving vision rehabilitation) will receive a follow-up visual field assessment using the wearable device at the David Chiossone Foundation - for the rehabilitation of blind, visually impaired, and frail people - Social Enterprise.
63 studies on the registry are indexed under Hemianopsia; 24 are open to participants now.
This study's planned enrollment of 300 is above the median of 32 across 53 interventional studies indexed under Hemianopsia.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

This group of patients will continue according to current clinical practice (control group), directed towards possible neuro-motor rehabilitation until full recovery, and will have access to visual rehabilitation following full recovery of physical condition. The follow up visual field test will detect the percentage of spontaneous recovery of the visual field defect during the observation period
Diagnostic Test: Early visual field test
The experimental group will be enrolled for a early rehabilitation intervention through multisensory stimulations, a rehabilitation specifically aimed at improving the visual field deficit, possibly combined with standard physical rehabilitation in temporary hospitalization facilities or protected hospital discharge.
Other: Early multisensory audio-visual stimulation training · Diagnostic Test: Early visual field test
Multisensory audio-visual stimulation training (using the device AV DESK Linari Medical) will last four weeks. Through audiovisual stimuli produced by the Av-Desk Flexi device, patients undergo a brain cell training program that compensates for blind spots in their visual field. The recipes regulating the combinations of stimuli are provided daily, under the supervision of a physician, where the data processing unit manages the data from the stimuli provided to the patient, their response to said stimuli, and monitors their position. The follow up visual field test will detect whether early intervention with multisensory audio-visual stimuli can improve visual field loss
Also known as: audio-visual stimulation
Visual field assessment with wearable devices (PalmScan VF2000) performed at the bedside in post-stroke patients who met the inclusion criteria during their stay in the neurology hospital unit, as soon as they were stabilized. Standard 120-point visual field tests will be performed on the left and right eyes separately, with the following quantification parameters: test duration, fixation losses, false positives, false negatives, points seen, points not seen, relative defects. Patients with a monocular residual perimetric defect of less than 106 points seen out of 124 (equal to 85% of the stimuli presented) and in any case with a defect greater than 12 points if presented in a single quadrant, will be selected for the clinical trial and invited to repeat the same visual field evaluation, using the same wearable devices in the 2-months follow-up.
Recovery rate in patients who receive training with multisensory audio-visual stimuli
Visual field test (120pt neuro programme) per each eye at follow up compared with the screening test. The functional rate will be in percentage (on 124 stimuli) adding 1 integer for seen points, 0.5 for relative points
Time frame: 2 months
Spontaneous recovery rate of visual field defects after stroke
Visual field test (120pt neuro programme) per each eye at follow up compared with the screening test. The functional rate will be in percentage (on 124 stimuli) adding 1 integer for seen points, 0.5 for relative points
Time frame: 2 months
Incidence of visual field defects in post-stroke patients
Number of patients with visual field defects, will be compared with literature and retrospective study on clinical records of the hospital neurology clinic.
Time frame: 1 year
