For more than a decade, an adjunct professor, Mary Ann Wharton, placed masking tape on the laboratory floor to teach students several geriatric activities where the tape remained on the floor for 2-3 months.  During this time, the tape became dirty and increasingly adherent to the floor.  Annually, the housekeeping staff encountered the challenge of removing the tape from the floor prior to cleaning and waxing.  Several years ago, the wax was applied to the floor without removing the tape.  As a result, a better way was sought to replace putting tape on the floor.  Additionally, I have witnessed the decline of mobility in family members (mother, father-in-law and uncle) and have researched literature on this subject which resulted in the development of the Mobility Assessment Tool (MAT).
