On the elderly care wards at my hospital we use the EMS on initial assessment and upon discharge to compare outcomes and useful for those readmitting patients to guage their progress. We use the published version 8-16cm and use a marked walking stick and ask them to lean forward with outstretched hands to measure. It depends on what type of Falls predictor you want to use. I personally have used varying test - depends on how rough and ready or quick you want them. n my experience the tests that are the most accuarate take longer and realistically time is limited so a maybe a rough quide of doing the 180 degree turn, the Get-Up-And-Go test, TUSS (Timed Unsupported Steady Stand) and 6m walk test may be sufficient.
