Discover the gold-standard balance evaluation protocol used by physical therapists worldwide. Learn administration guidelines, scoring criteria, and clinical interpretation for fall risk prediction.
📋 Berg Balance Scale Overview
Purpose: Quantifies static/dynamic balance in older adults & neurological patients
Time Required: 15-20 minutes
Equipment Needed:
- Stopwatch
- Ruler (measuring 12+ inches)
- Standard chair (17-19″ seat height)
- Step stool (8″ height)
CDC Validation: Scores ≤45 predict fall risk with 91% accuracy
📊 Test Items & Scoring Protocol
1️⃣ Sitting to Standing
“Please stand up without using your hands”
Scoring:
- 4: Able → Stand independently
- 3: Uses hands → Needs minimal aid
- 2: Requires multiple attempts
- 1: Needs moderate assistance
- 0: Unable
2️⃣ Standing Unsupported
“Stand for 2 minutes with arms at sides”
Timing:
- 4: >2 minutes
- 3: <2 minutes (safe)
- 2: Needs supervision
- 1: Stands briefly (<30s)
- 0: Unable
3️⃣ Sitting Unsupported
“Sit with arms folded for 2 minutes”
Posture Requirements:
- Feet flat
- Back straight
- No arm support
4️⃣ Standing to Sitting
“Sit down slowly without ‘plopping'”
Deductions:
- Uses hands
- Uncontrolled descent
- Misjudges distance
🧪 Challenging Items
8️⃣ Reaching Forward
“Reach forward with outstretched arm”
Measurement:
- 4: >10 inches
- 3: 5-10 inches
- 2: <5 inches safely
- 1: Supervision required
- 0: Loses balance
12️⃣ Alternate Stool Steps
“Place each foot alternately on stool”
Critical Form:
- Full foot contact
- Maintain upright posture
- Complete 8 steps in 20s
📈 Interpretation Guidelines
Score Range | Fall Risk Level | Intervention Needed |
---|---|---|
56 | Minimal | Education only |
45-55 | Low | Basic balance training |
36-44 | Moderate | Targeted PT program |
0-35 | High | Comprehensive intervention |
Clinical Notes:
- 4-point drop = significant decline
- Always retest after interventions
- Combine with Timed Up-and-Go (TUG)
✅ Administration Best Practices
- Environment: Well-lit, quiet space
- Footwear: Non-slip shoes/socks
- Demonstrate: Show each task clearly
- Safety: Stand close during dynamic tasks
- Documentation: Record compensations

🆚 BBS vs. Alternative Scales
Scale | Time | Focus | Limitations |
---|---|---|---|
BBS | 20 min | Comprehensive | Floor effect in severe impairment |
TUG | 3 min | Mobility | Less detailed |
POMA | 30 min | Gait+Balance | Complex scoring |
FGA | 15 min | Walking stability | Requires 5m walkway |
Choose BBS when detailed balance analysis is needed
