Device for Driving Simulation for the Rehabilitation of Balance and Proprioception

The DriveSim clinical trial investigates a dynamic driving simulator designed to train and assess functional motor and cognitive skills in individuals with neurological disorders. The study addresses a critical need in current rehabilitation practice, where maintaining patient engagement and providing ecologically valid training environments are essential yet challenging. Neurological conditions such as stroke, Parkinson's disease, amyotrophic lateral sclerosis and mild cognitive impairment often result in deficits in balance, proprioception, coordination, attention and motor planning, all of which critically affect daily functioning and driving ability. The novelty of this study lies in the integration of a three-degree-of-freedom motion platform with active steering, customizable haptic and inertial feedback, and adaptive task modules in a virtual urban scenario. This enables controlled, multisensory rehabilitation sessions that combine motor, vestibular and cognitive stimuli in a single system. The primary objective of the trial is to evaluate the safety, usability and feasibility of the DriveSim platform in both healthy individuals and patients with neurological impairment. Secondary objectives include assessing its impact on postural control, trunk and head stability, upper and lower limb motor performance, cognitive functions, perceived stress and fatigue, and quality of life. The study also aims to support the development of adaptive software capable of automatically adjusting task difficulty based on patient performance. By integrating functional tasks such as slalom, speed control, line keeping and reaction tests with customizable sensory feedback, this research has the potential to enhance the ecological validity of rehabilitation and to provide individualized motor-cognitive training. The expected outcome is a more engaging, adaptable and measurable rehabilitation pathway that may improve functional independence and support safer driving-related abilities in neurological populations.

Neurological conditions such as stroke, Parkinson's disease, amyotrophic lateral sclerosis and mild cognitive impairment are among the leading causes of long-term disability worldwide. These disorders profoundly affect motor coordination, postural stability, sensory integration, executive function and attention, with direct consequences on daily activities and overall independence. In current healthcare practice, rehabilitation is essential to maintain or recover functional abilities, but traditional interventions often lack ecological validity, offer limited multisensory stimulation and rely on repetitive, non-engaging exercises. As a result, there is a growing need for innovative rehabilitation tools capable of delivering realistic, quantifiable and cognitively stimulating training. State-of-the-art rehabilitation increasingly integrates technology to enhance patient interaction, measure performance and personalize the training load. Despite this progress, most existing systems do not combine dynamic body perturbation, interactive cognitive tasks and functional motor activities within a controllable scenario. Multisensory integration, which is essential for safe mobility and driving-related functions, remains insufficiently addressed in conventional therapy. This limitation is particularly evident when training tasks that require simultaneous postural control, visuospatial skills, rapid reaction, decision-making and coordinated use of upper and lower limbs. The DriveSim Rehab platform was conceived to fill this gap by providing a dynamic three-degree-of-freedom driving simulator equipped with active steering, configurable inertial feedback and a customizable virtual urban environment. Its multisensory nature enables the delivery of controlled proprioceptive, visual and motor challenges that mirror real-world demands while maintaining a safe clinical setting. This approach supports a more engaging and functionally meaningful form of rehabilitation, while enabling precise quantitative monitoring of motor and cognitive performance. The rationale of the study is to evaluate whether DriveSim Rehab can be safely and effectively integrated into rehabilitation pathways for individuals with neurological disorders. The primary objective is to assess the safety, usability and feasibility of the system during its use both in healthy subjects and in patients affected by stroke, Parkinson's disease, amyotrophic lateral sclerosis and mild cognitive impairment. These parameters are essential to determine whether the technology can be introduced into routine clinical practice without risk and with adequate user acceptance. Secondary objectives aim to determine the potential rehabilitative value of the platform. Specifically, the study evaluates its impact on head and trunk control, upper and lower limb motor performance, cognitive functions (including attention, visuospatial abilities and executive functions), perceived stress and fatigue, and quality of life.
