These are people who have been disabled due to some major sickness or some other problems. In order to help them carry on their work in the normal way, disability aids are manufactured. This helps them make their life a lot easier than what it would have been without these aids. The kind of disability aids that an individual might require depends on the person only. It is the problem that a person faces that decides the aids that he/she will use for carrying out their respective jobs. The following is the list of a few disability aids that come of significant use. The first and foremost aid is the stocking aid, aiding the individuals suffering from the problem of bending down to reach the foot and wear their own socks. These stocking aids have a gutter(槽) that is made up of plastic material. These gutters are shaped in a certain way along with the attachment of cotton tapes in it. The sock is then put over the gutter. The foot is placed inside the gutter. The cotton tapes help in pulling the socks up the leg and subsequently the sock. In this manner, the sock is worn by a person who has problems wearing it by bending one’s back and reaching the foot. There are openers that help the people who have problems with their hands or wrists to open bottles of ketchup, jam and other such bottles and jars that necessitates the use of hands and fingers. The third type of disability aids that comes to our minds are lifts. Now what are lifts? Lifts are certain machines that help in lifting people from specific areas, such as a bathtub or a set of stairs. These lifts are of varied types and come for numerous applications. It is for the individual to decide the type that he/she requires to use. For people, who have problems in balancing their upper bodies in a stable manner, there is something known as grab rails(扶手). These grab rails are installed for those who have mobility problems in their upper bodies. These rails come in varieties of shapes, sizes and angles. These grab rails are available to home users as well, in their different variations. One can purchase and fix one to their homes according to one’s specificities. These grab rails require the act of screwing and drilling in order to fix them to their appropriate place. The prices of these rails also vary according to the variation of their shapes and sizes. A portable book holder is a much sought-after disability aid. It can be used by anybody for that matter, not just the disabled. These portable book holders are light-weight and can be easily moved about. These holders relieve the strains on one’s hands, necks and shoulders that might occur due to the handling of a book. The holders are provided with extended legs that help in placing the reading material at suitable distance. Thus with the help of these disability aids, the old and disabled people can make their lives much more convenient and comfortable that would otherwise have been a cumbersome and complex one.
