The electric wheelchair is the greatest contribution from Canada to the entire world. In 1950, Dr. George Johann Klein developed this wonderful creation to make a revolution in the medical field. It was very useful at the time of Second World War and it helped to save many lives. Now different types of wheelchairs are available in the market. But all of them are derived from the old wheelchair which was invented several decades ago.
The electric wheelchair came as a great relief to the second World War veterans. Thousands of war victims were benefited by it. The electric wheelchair of Dr. Klein underwent many modifications. Today, there are many enhanced variants of it catering to specific customer needs.
Wheelchairs before electric wheelchairs were mainly designed for paraplegic persons. But Dr. Klein's creation had so many more features than a normal wheelchair. This wheelchair not only works for paraplegic people but it can also be used by quadriplegics. Its invention was very near to World War 2 so it made a great contribution to the Red Cross, and helped thousands of injured people.
The electric wheelchair is controlled by electronic devices operated by computer devices such as joysticks. There are some chairs regulated by puff/sip scanners or chin controls. These devices monitor the speed and direction of the chair as well as make it perform the functional motions and activities including tilting, stretching out, seat elevation and so on and so forth.
The main functions of an electric wheelchair are to help in movement. Besides going forward and backwards, movements like stretching and titling can also be done. Its movement is controlled by joy sticks; chin controls or sip/puff controls. We can control the wheelchair's direction, speed or other parameters by these joysticks.
The price of an electric powered wheelchair can be immense. The prices range from $1000 to $3000 for ordinary models while advanced models can cost $10,000 or more. They also may need frequent upkeep and repair work done. These are some of the disadvantages that electric wheelchairs present.
