A wheelchair is a mobility device designed to assist individuals with limited movement or disabilities. It typically consists of a seat mounted on wheels, allowing users to move independently or with assistance. Wheelchairs can be manual, requiring the user to propel themselves using hand rims, or powered, using an electric motor for movement. They come in various designs to accommodate different needs and preferences. Wheelchairs are often used by people with conditions such as spinal cord injuries, muscular dystrophy, or multiple sclerosis. They can be customized with features like adjustable seating, footrests, and armrests to enhance comfort and usability. Additionally, accessibility in public spaces is crucial for wheelchair users to navigate their environments safely.
