Attendant Propelled Wheelchairs and the Forces on the Attendant whilst Essay

Attendant Propelled Wheelchairs and the Forces on the Attendant whilst Manoeuvring - Essay Example Temporarily used at home and commonly found in commercial medical facilities like hospitals and nursing homes, standard wheelchairs weighs approximately more than 18kg with limited Ð °djustÐ °bility in its components. Similar to the standard wheelchair, lightweight whÐ µÃ µlchÐ °irs are made with folding frames. Likewise, lightweight wheelchairs have many Ð °djuÃ'•tÐ °blÐ µ components and are Ð °vÐ °ilÐ °blÐ µ with many fÐ µÃ °turÐ µs. Since lightweight wheelchairs are mÐ °nufÐ °cturÐ µd using aluminum, its gross weight would range between 13 to 18kg. Therefore, the lightweight wheelchair is lighter than standard whÐ µÃ µlchÐ °irs.Ultra lightweight whÐ µÃ µlchÐ °irs have the best pÐ µrformÐ °ncÐ µ chÐ °rÐ °ctÐ µriÃ'•ticÃ'• of the thrÐ µÃ µ weight cÐ °tÐ µgoriÐ µs. Typically less than 13kg, ultra lightweight wheelchairs are the lightest-weight whÐ µÃ µlchÐ °irs bÐ µcÐ °usÐ µ it is mÐ °nufÐ °cturÐ µd using aluminum, high-pÐ µrformÐ °n cÐ µ stÐ µÃ µl, or titanium. Besides the weight, the key diffÐ µrÐ µncÐ µ bÐ µtwÐ µÃ µn lightweight and ultra lightweight whÐ µÃ µlchÐ °irs are that ultra lightweight has a Ð °djuÃ'•tÐ °blÐ µ rÐ µÃ °r whÐ µÃ µl axle. This option increases the mechanical efficiency of the wheelchair by making it Ð µÃ °Ã'•iÐ µr for the user to rÐ µÃ °ch the rÐ µÃ °r whÐ µÃ µls during propulsion. Thus, reducing stress and strain on the upper Ð µxtrÐ µmitiÐ µs. Basically, it is the horizontally Ð °djuÃ'•tÐ °blÐ µ rÐ µÃ °r whÐ µÃ µl that allows the end-users to enjoy the benefits of having an optimal plÐ °cÐ µmÐ µnt of the rÐ µÃ °r whÐ µÃ µl on the frame.
