Motor Performance Improvement After Visual Rehabilitation

Condition(s) studied

Investigational drug(s) / intervention(s)

Virtual Reality rehabilitation: The study includes 12 weekly 45-minute visual rehabilitation sessions using a Virtual Reality device with Visionary Sport software. Originally designed for sports visual training, this software features gamified exercises to improve visual response times under professional supervision. Activities include games to enhance fixation, ocular motility, peripheral vision, and vergence. The "Peripheral Attention" activity trains reaction times to static stimuli perceived in the peripheral retina, adjustable to the patient's visual field defect. Stimuli can be placed at 10, 20, or 30 degrees in the peripheral field. The VR headset (Vive Focus 3) includes an eye tracker to monitor and adapt stimuli based on patient performance. Patients also perform 30 minutes of daily exercises at home, using proprietary software and Tobii 4C and 5C eye-tracking devices for ocular monitoring.

Study summary

Acquired brain injury" refers to brain damage that impacts neurological processing, making daily activities challenging and often causing vision issues like binocular dysfunction, oculomotor problems, and visual field loss. In Spain, visual rehabilitation is limited, although it is more common in other countries.

These patients generally need an interdisciplinary approach involving professionals like physiotherapists and optometrists and often face mobility, balance, and spatial perception difficulties. Treatment tools include lenses, prisms, and technologies like virtual reality (VR). The Visionary VR program, presented by Dr. Portela, has shown promising results in visual field recovery by stimulating the affected area.

Visual rehabilitation is based on brain plasticity and involves three key strategies:

Prisms to expand the visual field. Compensatory therapy to improve eye movement. Restitution therapy to restore the visual field.

Eligibility

Primary outcome measure(s)

• Visual field — 15 minutes
  The threshold test will be used in a 30-2 field size with fixation monitoring.
• Balance — 15 minutes
  The stabilometric study will be conducted using the Podoprint® pressure platform (Grupo Namrol, Barcelona, Spain). A balance assessment will be conducted after 6 sessions and after 12 sessions of treatment.
