Wheelchair Design Considerations

Figure 1. Head support (Retrieved from Guidelines for Use of Secondary Postural Support Devices by Wheelchair Users During Travel in Motor Vehicles, 2006) Anterior head support TransSPOT(2010) writes that the anterior head support is not a recommended postural support device of wheelchair users for transportation use because of the occupants may suffer from a neck hyperextension injury in a frontal car crash. If one is necessary to use this device or any form of forehead strap during transportation, Rehabilitation Engineering Research Center on Wheelchair Transportation Safety(2006) recommends that:  It should be automatically release but at the lowest force exerted during a crash and still able to maintain effective head support purpose  A soft neck collar that is independent of the wheelchair can be applied concurrently but not obstructing the airway like tracheostomy.  Beware the forehead strap from slipping downward and tying to the user’s neck Figure 2.

Sacroiliac belts, for example, place their compressive force between the sacrum and the hipbone. The use of lumbar supports is largely accepted because they are effective in preventing spinal injuries and treating spinal disorders. Orthopedic physicians often recommend or advocate the use of lumbar braces because they provide numerous benefits with few drawbacks. There are thirty different types of back braces and supports that are available for physicians to treat spinal disorders. These lumbar braces are effective at preventing primary back pain and secondary forms of back pain from occurring by providing the right stability and protection for the spine to prevent injuries from

The muscle fiber had an initial length of 1.4 cm and after adding the solution B, the length decreased to 1.2cm. This means that the muscle fiber contracted by 0.2cm while the muscle fibers treated with solutions A or C stayed at the initial length. The muscle contraction was not an expected result because it is known that both ATP and Ca+ are required in muscle contraction, however there was no Ca+ present in the experiment. So, why did the muscle contract? Because the muscle fiber was placed in glycerol before having added one of the three solutions, Ca+ is not required for muscle contraction.

He cannot use a cane or walker due to paralysis below the level of injury. Due to his upper extremity limitations, especially the permanent damage to the right wrist and hand, Lyle is unable to ambulate or propel a manual chair of any type. It is therefore recommended that Lyle be provided with a power wheelchair. A motorized wheelchair with tilt capabilities would provide him with optimal positioning and safety. The chair will provide him with appropriate positioning needs, as it will facilitate proper postural alignment and trunk

ASSISTIVE AND ADAPTIVE TECHNOLOGIES IN EDUCATION The use of assistive technology and adaptive tools by a person with disabilities can greatly increase their quality of life by increasing confidence, self-sufficiency, and independence. Assistive technology is the term for all assistive, adaptive as well as rehabilitative deceives that help people with disabilities. There are four classifications of Cerebral Palsy, each relates to how the muscles in the body are affected, and two common terms used to describe how the muscle tone is affected by the cerebral palsy. Hypotonia – low muscle tone, causing a loss of firmness and strength. Hypertonia – High muscle tone, causing rigidity and spasmodic movement.

new materials such as carbon fiber is being used, carbon fiber give the amputee a sense of life in the prosthetic because it feels more life like. - Bluetooth technology made the jump from the cell phone industry to prosthetics in 2007. Joshua Bleill received two prosthetic legs after combat in Iraq. Each leg had a Bluetooth device. Bluetooth is more often recognized for its ability to connect devices of technology without the use of wires.

Advances in sterile, germ free surgeries also improved the success rate of amputation procedures, increasing the need for prosthetic limbs. Before making the prosthetic limb they have to first measure the circumference and the diameter of the hand or leg the person is missing. They then make a mould with the same circumference and diameter as the

Take a look at these brands because they are well praised and reviewed. Once you have chosen a known tried and true brand name, you can be sure that you are buying both the name and the wheel chair that will be backed up with a guarantee and after sales service. The Major Motorized Wheelchair Brands Teftec Mobility is a leading brand that offers a range of motorized wheelchairs. These models come with many advanced features including adjustable seat height and a transmission steering system. Drive Medical is another major brand that offers a variety of motorized wheelchair models.

For example, is there was only one car manufacture, the automotive industry would greatly suffer for multiple reasons. Firstly, if a person wanted to buy a new car, there would only be one option to buy from. The car company could pick any price arbitrarily because there would be no competing car companies. The car company could also sell low quality cars. It would not make a difference because there would be no industry standard.

Seat elevation in power mobility Vertical mobility is as important as horizontal mobility for wheelchair users and it is not always properly considered. The common system to provide the user with vertical mobility is the seat elevation system. This system makes the complete seating system to raise and lower the person in the wheelchair while keeping the seat to back and seat to floor angles, giving him or her access to multiple vertical levels. This possibility does not only have physical and functional benefits, but also the ability to actively take part in other life aspects and situations without needing help or assistance of another person, or without the risk of having injuries. Physical and Functional Benefits Using seat elevation results in reaching and accessing higher levels.

The AGG also allows for unrestricted rotation. “One custom device was designed to have clubs attach directly to the prosthesis.” (Radocy 1987) This alternative may solve control problems for amputee

Discuss the difference between a physical topology and a logical topology. Why are both necessary? Answer: The difference between a physical topology and a logical topology is that a physical topology applies to how the hardware of the various computers, cables, switches, routers, and other devices in a network fit physically or wirelessly together. A logical topology describes how software controls access to a network and the sharing of its specific resources such as applications and databases. Both a physical and logical topology are necessary to complete the whole of a network’s functionality.

Moreover, chiropractic treatment does not require patients to pay the medicine and any other instrument’s fee, so it would not cost too much. For the patients, they do not want to pay much money for therapy, even some of them could not offer many treatments. Fortunately, chiropractic would cost low price and could provide successful therapy to patients. Therefore, chiropractic is superior to western
