Wheelchair

A wheelchair is a chair mounted on wheels designed to aid mobility for people with limited walking ability, injuries, or other conditions. It enables independent movement, transfers, and access to daily activities.

Common types include manual wheelchairs, powered (electric) wheelchairs, sports chairs, pediatric chairs, and standing chairs. Manual chairs may be folded for transport and are propelled by the user via rear rims or by a caregiver. They come in rear-wheel drive, mid-wheel drive, or front-wheel drive configurations, and with rigid or folding frames. Powered wheelchairs use batteries and a control device such as a joystick, offering longer range and less upper-body effort. Sports chairs are lightweight and highly maneuverable; pediatric chairs are sized for children; standing chairs allow an upright posture.

Key components and features: frames are typically made from steel, aluminum, titanium, or carbon fiber. Rear wheels with push rims and smaller front caster wheels provide movement. Brakes or wheel locks, anti-tip devices, footrests, leg supports, and adjustable armrests contribute to safety and comfort. Seating systems may include cushions, back supports, and trunk stabilization; various accessories are available, such as headrests, trays, and bags.

Usage and care: Wheelchairs are used indoors and outdoors and should be properly fitted to optimize weight distribution and pressure relief, reducing fatigue and skin breakdown. Regular maintenance includes inspecting brakes, tires, upholstery, and frame integrity, and ensuring cushions and seating adjustments remain correct for the user.
