The Power Chair as a Cognitive Aid for Users with Neurological Conditions

For individuals living with neurological conditions such as Traumatic Brain Injury (TBI), certain forms of dementia, or cognitive fatigue from Multiple Sclerosis, a power wheelchair can serve a dual purpose. Beyond physical mobility, it can be strategically configured to reduce cognitive load, enhance safety, and support executive functioning, becoming an integral part of a comprehensive care strategy.

The core principle is simplification and automation. Programmable navigation routes are invaluable. A user can travel from their bedroom to the kitchen by selecting a single, pre-mapped "Kitchen" button, rather than navigating complex joystick maneuvers. This reduces decision fatigue and disorientation. Geofencing can create safe zones, with the chair automatically slowing down or providing alerts near potential hazards like stairs or exits.

Interfaces can be tailored to cognitive abilities. For some, a simplified controller with large, picture-based buttons for "Home," "Bed," or "Door" is more intuitive than a standard joystick. For others, voice-command integration allows them to state their destination directly. Reminder systems can be integrated, using gentle auditory cues or controller vibrations to prompt actions like pressure relief shifts or medication times.

Safety features become cognitive safeguards. Automated obstacle detection and stop functions provide a critical backup for moments of inattention. A "Return to Base" function can guide the chair back to a charging dock or central location if a user becomes confused. For caregivers, remote monitoring provides peace of mind, allowing them to check location and status discreetly. In this application, the power chair transforms from a simple vehicle into a supportive, intelligent environment that compensates for cognitive challenges and promotes greater autonomy.
