Invacare 9000 XT Manual Wheelchair (Custom)

This will insure the best performance for navigating tight areas both inside the home as well out in public spaces.

A wheelchair that is too narrow or too wide can cause discomfort. When too narrow, a wheelchair can become restrictive and increase the likelihood of pressure sores, while when it's too wide, becomes more difficult to push due to the angle of the arms from the shoulders to the wheels.

To determine the necessary seat width, measure the rider's widest area of the body and add one inch. This will allow for optimum seat width while maintaining ideal usability, comfort and safety.

To determine the appropriate seat depth, measure from the back of a chair to the inside of your knee. Subtract one inch to assure no contact is made between the edge of the wheelchair seat and the inside of your leg, which could cause discomfort and prevent the rider from sitting back fully in the chair.

Make sure you'll be positioned correctly in your wheelchair and can sit at your desk or kitchen table. Standard tables/counters have a knee clearance of 27 inches.

Casters typically come in sizes from 3"" to 8"". The smaller the caster the better the maneuverability of the chair and the less likely it is to shimmy. But smaller casters on unpaved surfaces, riding in and out of elevators, or passing over street grates can be more problematic. Smaller casters are typical of chairs used for sports like basketball, which is played on an even, hard surface, yet their maneuverability makes them popular for everyday use. 3"" casters require the most riding skill and may not be the best choice for a first time wheelchair user.

The large 8", pneumatic (air-filled) caster provides the softest ride and easily rolls over bumps and raised surface, yet makes propelling the chair more difficult. Because of their size, 8"" casters can be an obstruction coming into contact with furniture or the rider's foot. Pneumatic tires need to be kept inflated with the correct pressure, and are capable of going flat.

4" to 6" casters offer a good combination of maneuverability, performance and ease of riding over surface obstructions. Composite (airless) casters offer better durability and quicker ride, while pneumatic casters provide a softer, slower experience.

When armrests are not fitted properly the wheelchair can become more difficult to push. Not all armrests are adjustable. Height should be fitted to allow the forearm to rest fully on the armrest without pushing up on the shoulders. For users who sit at a table or desk, swing-away armrest can beneficial.

There are four basic types of armrests:
1. Full length, fixed height (entire armrest is padded with a non-adjustable height)

2. Full length, adjustable height (entire armrest is padded with various height seetings)

3. Desk length, fixed height (partial armrest is padded for easier access with tables, non-adjustable height)

4. Desk length, adjustable height (partial armrest is padded for easier access with tables, various height seetings)

Armrest that can be easily removed or flip up and down gives users the choice of when to use the armrests.

There are two types of rear wheels, Spoked Wheels and "molded" Mag Wheels.

1. Spoked Wheels are made of metal and are similar in appearance to that of bicycle wheels. The number and size of the spokes affect durability, shock absorption, weight, and performance. The more spokes, the more stable the wheel will be.

2. Mag Wheels are made of molded plastic or a composite. They have a small number of wide molded spokes that are an integral part of the wheel. Mag wheels are more durable, require less maintenance, and usually weigh more then spoked wheels.

Using wheel locks as a braking device can cause injury and excessive tire wear and should never be used in this manner.

There are various types of wheel locks available:

1. Push-to-lock wheel locks are the most common. The break is engaged by the rider pushing forward and applying pressure with the palm of their hand until the lever snaps into position.

2. Pull-to-lock wheel locks work in the same manner as the push-to-pock except the lever is pulled forward. For some riders, it may be easier because it does not require as much upper body mobility needed to push the lever away from the body.

3. Swing-away, low-mount and under-mount wheel locks work in different ways depending on the style. These wheel locks help you avoid hitting your thumbs when pushing directly on the tires by mounting the wheel locks away from this range of motion. Due to its location, some riders with limited mobility may not be able to engage these wheel locks.

Wheel lock extensions provide a greater lever arm to apply and remove the locking mechanism, making the wheel locks easier to engage for a rider with decreased upper strength.
