This range of abilities makes it difficult to evaluate functioning using a single instrument.

Using the original SPPB scoring criteria, 73.0% of centenarian men and 86.0% of centenarian women are identified as severely impaired by the scale's original classification scheme. Results suggest that conventional norms for older adults need substantial revision for centenarian populations and that item response theory methods can be helpful to address floor and ceiling effects found with any single measure.<\/jats:p>","DOI":"10.1155\/2010\/310610","type":"journal-article","created":{"date-parts":[[2010,9,14]],"date-time":"2010-09-14T18:05:27Z","timestamp":1284487527000},"page":"1-6","source":"Crossref","is-referenced-by-count":23,"title":["Assessing Physical Performance in Centenarians: Norms and an Extended Scale from the Georgia Centenarian Study"],"prefix":"10.1155","volume":"2010","author":[{"given":"M.
