A wheelchair is a device used for mobility by people who have difficulty walking or moving due to illness, injury, disability or impairment. It is designed to be propelled manually or by an electric motor and typically consists of a seat, backrest, footrests, and two large wheels in the back and two smaller wheels in the front. Wheelchairs come in a variety of sizes, and some models are designed for specific purposes, such as sports or outdoor activities. Their use enables many people to have a greater degree of independence and allows them to participate more fully in daily activities.

There are several types of wheelchairs available on the market, including:

1.Manual wheelchairs: These are self-propelled by the user and require upper body strength to use.

2.Power wheelchairs: These are electrically powered and are suitable for people who have limited upper body strength or endurance.

3.Transport wheelchairs: These are lightweight and designed for short distances and easy transport.

4.Sports wheelchairs: These are designed for athletic activities such as basketball, tennis or racing and are usually made of lightweight materials for increased maneuverability.

5.Pediatric wheelchairs: These are designed for children and come in a variety of sizes and styles.

6.Bariatric wheelchairs: These are designed for individuals who weigh more than 250 pounds and can accommodate a greater weight capacity.

7.Standing wheelchairs: These are designed to elevate the user into a standing position, offering greater access to the environment.

The choice of wheelchair will depend on the needs of the individual user.
