Abstract
There are people who, despite being perfectly able mentally and visually, are unable to use a powered wheelchair because they cannot manage any of the standard controls due to their physical disability. An initial study had been undertaken partly to establish how many people were involved and to see if it was viable to invest money into developing more sophisticated controls. Before this stage was reached, it was important to make sure that all the controls currently available had been tried. Alternative controls clinics were therefore set up to fulfil this need. It was found that not all but most problems could be solved by adapting standard equipment or perhaps using it in a different way. Two case histories are used to demonstrate some of the problems encountered in the alternative controls clinic.
