Today, in part one of our two part series, we're taking a close look at the methods for performing pre-operative functional capacity assessments and their utility in predicting patient outcomes. In part 1, we focus our discussion on METS, activities of daily living (ADLs) and the DASI score.

In part two - which will be released in a fortnight - we'll cover the M-DASI, the 6-minute walk test.
