Objective[edit | edit source]
The Balance Outcome Measure for Elder Rehabilitation (BOOMER) was developed to assist in clinical practice to quantify standing balance.[1] The combination of a variety of commonly used, single-item outcome measures makes the BOOMER a highly feasible and applicable tool that is both time and resource efficient[1].
Intended Population[edit | edit source]
Older adults with deficiencies in standing balance.[2]
Method of Use[edit | edit source]
Instructions[edit | edit source]
The BOOMER consists of the following four tests:
| Test | Description |
|---|---|
| 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. |
The four components of the BOOMER are performed in one session. Areas of interest are identified with treatment continued accordingly.
Scoring[edit | edit source]
An individual's performance on each measure will be converted to a 5-point ordinal scale. The scale ranges from 0 (unable to perform the test/0 on Functional Reach) to 4 (excellent) with a maximum score of 16.[2]
Table: BOOMER scoring[2]
| Test | Scoring | ||||
| 0 | 1 | 2 | 3 | 4 | |
| Step test (average number of steps) | Unable | 0 - 5 | 5 - 8 | 8 - 12 | >12 |
| TUG (seconds) | Unable | ≥ 30 |
29 - 20 | 19 - 10 | <10 |
| FR (centimetres) | 0 | 1 - 15 | 16 - 20 | 21 - 30 | > 30 |
| Timed Static Stance (seconds) | Unable | 0 - 30 | 30 - 60 | 60 - <90 | 90 |
Evidence[edit | edit source]
Validity[edit | edit source]
Concurrent validity[edit | edit source]
The BOOMER correlates with Functional Independence Measure and Modified Elderly Mobility Scale[1]. It has shown high correlation with the Berg Balance Scale at both admission (ρ=.91; P<.01) and on discharge (ρ=.68; P<.01) from geriatric rehabilitation units (n=134)[2].
Construct validity[edit | edit source]
Another study[3] showed that BOOMER scores highly associated with BBS scores (r = .93, p < 0.001), as well as with raw scores on the de Morton Mobility Index (r = .89, p < 0.001). The same study showed only moderate associations with perceived confidence on the Activities-specific Balance Confidence scale (r > .52, p < 0.001).
Responsiveness[edit | edit source]
A minimum clinically significant change in the BOOMER is 3 points over its 17-point scale range[1]. Change scores between admission and discharge for the BOOMER and BBS displayed moderate correlation (ρ=.55; P<.01), while those between the BOOMER and gait speed displayed only fair correlation (ρ=.33 P<.01)[2].
