The electric wheelchair was discovered by the greatest Canadian inventor of all time, George Johann Klein in the 1950s. The electric powered wheelchair came as a great aid to quadriplegics whereas normal wheelchairs were useful only to paraplegics. This instrument was the result of Dr. Klein's work with a lot of medical specialists, patients, scientists and engineers.
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.
The wheelchair today is found useful not only by the invalids and quadriplegics; but also persons with cardiovascular irregularities. The models now available are meant for both indoors and outdoors. Some models are compact and portable with various features.
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 electric powered wheelchair is very much a boon to those whose life has been limited because of their disability. They will no longer need an external help to move around and perform the basic functions. They can be self-reliant to a great extent.
But electric wheelchairs are very expensive with the prices ranging between 1000 and 3000 dollars. Advanced models can cost up to 10,000! They may also require constant servicing. However, transporting someone on a non-powered wheelchair can be quite a task, so in cases where the person needs extra help from a motor to move along, an electric powered wheelchair is great to have.
