The BOOMER consists of the following four tests: Step Test One foot is repeatedly placed on top of a 7.5cm step and returned back down to the ground as many times as able in 15 sec. The average between legs is then calculated for scoring. Timed Up and Go From a seated position, individual stands, walks 3m, turns 180°, walks 3m back to chair and sits down with back resting against backrest. Functional Reach Individual reaches as far forward as possible in a standing position without losing balance. Timed Static Stance Standing with feet together and eyes closed. An individual's performance on each measure will be converted to a 5-point ordinal scale.
