The Berg Balance Scale (BBS) is one of the most widely used outcome measures to assess static and dynamic balance in clinical practice. It consists of 14 functional tasks and provides a standardized way to evaluate a patient’s balance, fall risk, and functional mobility.
In neurologic physical therapy, the BBS is commonly used across many patient populations to assess fall risk, guide treatment planning, and track progress.
In this blog post we will discuss:
- Which patients should be assessed with the BBS
- How to administer the test in the recommended standardized way
- Cutoff scores, minimal detectable change (MDC), and how to interpret results and write goals
Part I: Which Patient Populations Are Appropriate to Assess With the BBS?
The Berg Balance Scale is appropriate for a wide range of patients, particularly those with balance impairments or increased fall risk.
It has been extensively studied in:
- Stroke
- Parkinson’s disease
- Older adults
- Traumatic brain injury
- Multiple sclerosis
The BBS is best suited for individuals who can:
- Follow simple instructions
- Maintain unsupported sitting
- Attempt standing tasks with or without assistance
Because the test includes progressively more challenging tasks, it can capture a range of abilities from basic sitting balance to higher-level standing balance tasks.
Use of assistive devices
Use of assistive devices is not recommended when administering the BBS.
Providing assistance during the test
The goal of the BBS is to assess what the patient can do independently.
- If physical assistance is required to complete a task, the score for that item will reflect this (typically scored as 1 or zero depending on the task).
- Provide assistance only as necessary for safety, and document any assistance provided and if the patient demonstrated a loss of balance.
When the BBS may not be appropriate
The BBS may not be the best choice for:
- Patients who are non-ambulatory or unable to stand
- Individuals with very high-level balance abilities (ceiling effect)
- Patients with significant cognitive impairments limiting ability to follow instructions
In these cases, alternative outcome measures (e.g., Function in Sitting Test, Functional Gait Assessment, Mini-BESTest) may be more appropriate.
If a patient is not currently able to sit unsupported, but you expect they will progress, it is recommended to document the BBS on evaluation with a score of 0.
Part II: How Do I Correctly Administer the BBS?
Standardized administration is critical for reliability and validity.
Test structure
The BBS consists of 14 tasks, each scored on an ordinal 0–4 scale, with:
- 0 = unable to perform
- 4 = independent performance
Maximum score: 56
Tasks include:
- Sitting to standing
- Standing unsupported
- Transfers
- Reaching forward
- Turning
- Picking up an object from the floor from standing
See the full test with instructions here.
Test administration
- Each task is performed once, with clear standardized instructions
- The clinician scores performance based on time, distance, and level of assistance or if supervision is required
The total score is calculated by adding points from all 14 items.
Equipment needed
The BBS requires minimal equipment:
- Standard chair (with and without armrests)
- Stopwatch
- Ruler or measuring device
- Step or stool (7 3/4 – 9 inches in height)
- Slipper or shoe (object to be picked up from floor)
Part III: BBS Cutoff Scores, MDC, and Interpretation
Understanding how to interpret BBS scores allows clinicians to assess fall risk, balance impairment, and functional ability.
Interpreting Total Scores
General interpretation guidelines:
| Score | Interpretation |
| 0-20 | High Fall Risk |
| 21-40 | Moderate Fall Risk |
| 41-56 | Low Fall Risk |
A commonly cited cutoff:
- <45/56 is associated with increased fall risk (Berg et al., 1992)
However, fall risk is multifactorial, so BBS scores should be interpreted in combination with clinical judgment and other assessments.
Minimal Detectable Change (MDC)
MDC values vary by population and baseline function.
Stroke
- MDC: ~6–7 points (acute stroke), 4.66-6.7 (chronic)
Parkinson’s Disease
- MDC: ~5 points (Hoehn & Yahr stages 1-4)
- Likely more limited in utility in middle-stage Parkinson’s due to ceiling effects.
Older Adults
-
- MDC: ~4–6 points
- History of falls + BBS < 51 OR no history of falls + BBS < 42 predictive of falls
- Score of < 40 on BBS associated with almost 100% fall risk
Multiple Sclerosis
- MDC: ~5.8-6.9 points
SCI
- No clear MDC
- Normative data for patients with ASIA D who can walk 10m independently (with or without walking assistive devices):
- Mean BBS: 47.9; ranging from 17-56
- Mean BBS for paraplegia: 44.8, ranging from 17-56
- Mean BBS for tetraplegia: 50.7, ranging from 31-56
- However, it has been reported that there is no significant relationship between total falls and BBS scores, and there is no cutoff score that reliably differentiates fallers from non-fallers.
- Studies have shown that BBS is a valid assessment tool for measuring balance in SCI
Brain Injury
- MDC: ~6 points
Functional Interpretation
Increased BBS scores can reflect meaningful improvements in:
- Static and dynamic balance
- Fall risk
- Functional mobility
- Independence with transfers and standing tasks
However, the BBS does have limitations:
- Ceiling effect in higher-functioning individuals; likely better to utilize other outcome measures, such as the Functional Gait Assessment
- Limited assessment of dynamic gait balance
- Does not capture reactive balance
Because of this, it is often used alongside other outcome measures.
Writing Berg Balance Scale Goals
When writing goals based on the BBS, consider:
- Baseline score
- MDC values
- Do not forget functional implications to drive home the real-world relevance of the goal
Example 1
Goal:
Patient will improve Berg Balance Scale score from 32 to 38, demonstrating reduced fall risk and improved safety with household mobility within 4 weeks.
Example 2
Goal:
Patient will improve Berg Balance Scale score from 38 to ≥45 to improve safety and independence with transfers and standing tasks and progress toward prior level of function within 6 weeks.
Example 3
Goal:
Patient will improve Berg Balance Scale score from 48 to 52 to enhance higher-level balance skills and reduce fall risk during community mobility within 2 weeks.
Key Takeaways
The Berg Balance Scale is a valuable tool because it:
- Provides a standardized assessment of balance
- Helps determine fall risk
- Is relatively quick and easy to administer
- Is widely validated across neurologic populations
When used alongside other outcome measures, the BBS can help clinicians:
- Track progress over time
- Guide treatment planning
- Write measurable, meaningful goals
