A standard balance test
The Berg Balance Scale was developed by Katherine Berg and colleagues in 1989 to measure balance in older adults. It is a performance test: the patient carries out 14 tasks drawn from daily life, and the examiner rates each from 0 (unable) to 4 (independent and safe), for a total out of 56. Physical therapists use it to estimate fall risk, set goals and track progress after a stroke or in Parkinson’s disease.
The 14 tasks
- Sitting to standing
- Standing unsupported for two minutes
- Sitting unsupported for two minutes
- Standing to sitting
- Transfers between two chairs
- Standing with eyes closed
- Standing with feet together
- Reaching forward with an outstretched arm
- Picking up an object from the floor
- Turning to look behind over each shoulder
- Turning a full circle
- Placing alternate feet on a step or stool
- Standing with one foot in front of the other
- Standing on one leg
Interpreting the score
| Score | Fall risk |
|---|---|
| 0 – 20 | High: usually needs a wheelchair |
| 21 – 40 | Medium: walks with assistance |
| 41 – 56 | Low: independent |
Many studies also use a cut-off of 45: below it, older adults living at home are more likely to fall, and a walking aid or a balance program is often recommended.
Example
A patient who scores 4 on most tasks but loses points on standing with eyes closed, reaching forward, turning a full circle, placing feet on a step, tandem stance and standing on one leg reaches a total of 49. That is a low fall risk, with weak points in the dynamic and single-leg tasks that a targeted exercise program can address.
Practical tips
Use a stopwatch, a ruler, a chair with arms and one without, and a step or stool about 7 to 8 inches high. Demonstrate each task, allow the patient to choose the leg for one-leg items, and score the lowest category that applies. The test takes about 15 to 20 minutes. It has a ceiling effect in active people, who often score 56 even though they could still improve, so faster tests may suit them better.
