CUSTOM ADAPTATION PURPOSE: To provide a customized one-handed chopping board for an individual with hemiplegia resulting from a stroke. The board base made of 16-millimeter plywood with a non-slip rubber underlay to prevent it from moving on the marble tabletop. The base has a laminex overlay and oiled hardwood edging. On the right side of the base there are two strips of polypropylene cutting board material, with two “jaws” mounted between them. The jaws have textured grooves on the inside faces to assist with holding the material to be chopped. One jaw is fixed in place using two stainless steel dowels, while the other slides in the track between the two polypropylene strips using a simple lever cam to lock it in place. The moveable jaw can be adjusted for sizes up to a maximum of 100 millimeters. On the left side of the base, the section furthest away from the user as she stands at the table contains another polypropylene strip. On this is mounted an adjustable holder for her chopping knife. With the tip of the knife inserted into the holder, the user simply moves the knife up and down to chop something like a carrot that is held in the jaws. This significantly reduces the effort required compared with repositioning the knife for every stroke. This is particularly useful as the individual was originally right handed and she is now using the knife with her left hand. If the patron needs to slice something like bread, she can take the knife out of the holder and use it the normal way. The actual chopping board section is another rectangular piece of polypropylene with a drainage groove all the way around. The chopping board section and the two jaws are removable for cleaning.
