Are we all speaking the same language in seating and mobility? Have you heard a wheelchair cushion being called a “pillow” by someone who does not work in this field? Do you call a “wheel lock” a “brake” on a wheelchair or an arm support an “armrest”? Is a pelvic positioning belt the same as a pelvic belt for transportation of occupied wheelchairs? (The answer to this last question is no!) The language of seating and mobility is evolving and, in fact, becoming standardized. This month, Clinical Corner will address standardized terms in seating and mobility. We will look at why standardization in terms is important and review a sampling of common terms.
