Questionnaire showed that places of greatest need of the bar were the bathroom and the fourth

The occupational therapist Danielle Aline Cheap Assad developed a device that helps people who have suffered stroke, traumatic brain injury or even seniors and other patients with compromised motor area.

The novelty is a support bar modular removable elaborated to be applied beside of beds and sanitary vases. The object assists in support of those lifts, providing support for the hands in this movement. Without the bar, the people, usually if support us mobile or ask to some relative uplift them. So, they end up having to always have someone around to make the move. The bar is dismountable and, why, adapts to size of the environment in which will be placed, affirms the researcher.

The equipment was developed thinking mainly in low-income population. The bars that I researched have to be sinkers in the wall, tells the occupational therapist. During its trajectory academic, she realized that many times these people live in rented houses or lent and owners do not allow fixing these objects. Furthermore, another problem is that the bars available in market are sold in sizes that do not adapt to space availability of their homes.

Another important detail is the mode if remove the object's base from the floor. The new bar is fixed by an adhesive thermoreversible, consisting of beeswax, paraffin and rosin. Why this, simply just the heating a hairdryer, eg, for her if unglue from the floor. In step of development, Danielle had of opting between fixation by suction cups or by this compound. The deployment of suckers was discarded because this piece requires smooth surfaces to glue.

Entire idealization of final product was made based on a questionnaire, applied to 100 volunteers in beginning of the research. The answers indicated that the locations of greatest need of this support were the bathroom and the room.

After of this step, was held a search based on standards established for the development of grab bars. The chosen was the NBR 9050, which normatizes the accessibility of edifications and indicates measures and materials with which can be done the product.

The another phase the research consisted in choice of materials, according with his market availability, price and respect to the norm. We verified that aluminum catered to our needs.

The work was result of master's by the Program Postgraduate Interunits in Bioengineering, a partnership between the School of Engineering of São Carlos (EESC), the Institute of Chemistry of São Carlos (IQSC) and the Faculty of Medicine of Ribeirão Preto (FMRP) , all of USP.
