Berg Balance Scale
Berg Balance Scale: 14-task performance-based assessment. Score 0–56. Each task observed directly by a trained clinician.
Score each task by direct observation (0–4)
1. Sitting to Standing
2. Standing Unsupported (2 min)
3. Sitting Unsupported (2 min)
4. Standing to Sitting
5. Transfers (chair to chair)
6. Standing Eyes Closed (10 sec)
7. Standing Feet Together (1 min)
8. Reaching Forward (Functional Reach)
9. Pick Up Object from Floor
10. Turning to Look Behind
11. Turning 360 Degrees
12. Alternating Foot Taps (8 times each)
13. Tandem Standing
14. Standing on One Leg
Guidelines & Evidence
Clinical Details
Section 1
When to Use
When to Use
Baseline and serial balance assessment in stroke, Parkinson's disease, and frailty rehabilitation.
Predicting fall risk in community-dwelling and hospitalised older adults.
Monitoring response to physiotherapy interventions targeting balance and gait.
Pre-discharge balance clearance for older adults following hip fracture repair or prolonged bed rest.
Gold Standard for Balance
The BBS is the most widely validated performance-based balance tool in rehabilitation medicine, with >1,000 publications supporting its use across stroke, Parkinson's disease, multiple sclerosis, and geriatric populations.
Section 2
Formula & Logic
Scoring
14 tasks, each scored 0–4 by direct clinician observation
Total score: 0–56
41–56: Low fall risk (ambulatory, independent)
21–40: Medium fall risk (walking aid required)
0–20: High fall risk (wheelchair dependent)
Each 1-point drop below 45 = 3–4% increased fall risk
14 Test Items
1. Sitting to standing
Scored 0–4 by independence and stability
2. Standing unsupported
2 minutes without support
3. Sitting unsupported
2 minutes with back unsupported, feet on floor
4. Standing to sitting
Control of lowering to chair
5. Transfers
Chair to chair with armrests
6. Standing with eyes closed
10 seconds eyes closed
7. Standing feet together
1 minute with feet together
8. Reaching forward
Functional reach with outstretched arm
9. Retrieving object from floor
Pick up shoe from floor
10. Turning to look behind
Looking over both shoulders
11. Turning 360 degrees
Full rotation each direction
12. Alternating foot taps
Stepping on stool, 8 times each foot
13. Tandem standing
One foot directly in front of the other
14. Standing on one leg
Maximum 10 seconds

Pearls/Pitfalls
BBS vs. Timed Up and Go (TUG)
The BBS takes 15–20 minutes and requires direct observation by a trained clinician. The TUG is faster (< 5 min) and suitable for screening. For comprehensive rehabilitation planning, BBS provides granular task-level data to guide targeted physiotherapy. Use TUG for screening; use BBS for depth.
Ceiling Effect Warning
The BBS has a known ceiling effect in high-functioning community-dwelling adults — patients scoring 54–56 may still fall. In these cases, the Mini-BESTest or Dynamic Gait Index provides better discrimination. For scores < 45, the BBS remains discriminative and sensitive to change.

Next Steps
Rehabilitation Actions by Score
41–56 (Low Risk)
Community ambulation goal. Progress to dynamic balance and dual-task training.
21–40 (Medium Risk)
Walking aid assessment. Targeted sit-to-stand, step, and transfer training.
Minimum Detectable Change (MDC) = 4–7 points in stroke and Parkinson's populations. A change of < 4 points should not be interpreted as genuine improvement beyond measurement error.

Measuring balance in the elderly: validation of an instrument.

Origins
Katherine Berg, McMaster University
Developed by Katherine Berg and colleagues at McMaster University in Hamilton, Canada, and first published in 1989. The scale was designed to objectively measure balance during functional tasks rather than relying on subjective clinician impression or simple one-item tests. It has since become the international gold standard for balance assessment in rehabilitation, used across >80 countries.
