The Berg Balance Scale: How Physiotherapists Assess Fall Risk
The Berg Balance Scale (BBS) is the most widely used and validated tool for assessing balance and fall risk in older adults. Developed in the late 1980s, it has become the gold standard in both clinical practice and research. Understanding what it measures helps patients and families make sense of their assessment results.
The BBS consists of fourteen tasks that simulate daily activities. Each is scored from zero (unable to perform) to four (performs independently and safely), giving a maximum score of fifty-six. The tasks include: sitting to standing, standing unsupported, sitting unsupported, standing to sitting, transfers, standing with eyes closed, standing with feet together, reaching forward, retrieving an object from the floor, turning to look behind, turning 360 degrees, placing alternate feet on a stool, standing with one foot in front (tandem), and standing on one leg.
The scores are interpreted as follows: 0–20 indicates high fall risk (typically wheelchair-dependent), 21–40 indicates medium fall risk (may walk with assistance), and 41–56 indicates low fall risk (independent ambulator). A score of 45 or below is generally considered to indicate increased fall risk, and a decrease of four or more points is considered a clinically significant change.
The BBS is just one of several assessment tools your physiotherapist may use. Others include the Timed Up and Go test (measuring the time taken to stand from a chair, walk three metres, turn, and sit back down — more than 12 seconds indicates increased fall risk) and the Functional Reach Test (measuring how far you can reach forward while standing — less than 15 centimetres indicates high fall risk).
These assessments provide objective measurements of your balance and fall risk, allowing your physiotherapist to track progress over time and adjust your treatment programme accordingly.
Our falls prevention service uses these validated assessments as part of a comprehensive falls risk evaluation. Our elderly physiotherapy service incorporates regular reassessment to monitor progress and ensure your programme remains appropriate as your abilities change.
