Virtual Reality and Neurostimulation for Early Stroke Rehabilitation

Recruiting now · Not applicable

Conditions studied: Stroke

In brief

Stroke is one of the leading causes of disability, leaving millions of individuals each year impaired with lasting motor and sensory impairments. In the subacute phase, which goes from the first week to 3 months post-stroke, the patient has the highest recovery, which could be boosted by proper technologies intended for the rehabilitation of the patients. The impairments that the patients experience are extremely heterogeneous and go from muscle weakness to spasticity of the paretic side of the body. Beyond motor deficits, stroke survivors also suffer from sensory impairment (they do not properly feel with the paretic side of their body), impaired body representation (misjudging the size, position, and movement of their affected limb), which can further hinder recovery. Traditional rehabilitation primarily targets motor function, often without considering at all the role of sensory feedback and body perception in the recovery process. However, growing evidence suggests that the combination of multiple sensory modalities towards a multifaceted rehabilitation can enhance neuroplasticity and improve rehabilitation outcomes. To address this, the investigators have developed a novel rehabilitation approach that integrates immersive virtual reality (VR) with transcutaneous electrical nerve stimulation (TENS). This system allows stroke patients to interact with a virtual environment while receiving synchronized tactile stimulation, reinforcing sensorimotor integration. Unlike conventional therapy, which relies on passive or repetitive exercises, this approach engages patients in active, goal-oriented movements, tailored to their individual recovery progress. By focusing on the subacute stroke population, this project aims to leverage the brain's heightened plasticity during early recovery to maximize functional improvements. The VR-based intervention will adapt to each patient's motor abilities, providing real-time feedback to encourage precise movements and enhance sensory processing. Through this multisensory experience, the investigators seek to improve not only motor control but also sensory and body representation measures.
