Which statement best describes the Berg Balance Scale’s applicability to different populations?

• A. It has floor and ceiling effects, limiting use in very impaired or very high functioning individuals.
• B. It provides precise measurement across all function levels without any ceiling/floor limitations.
• C. It measures only cardiovascular endurance.
• D. It is inappropriate for clinical use.

Answer: (A)

Floor and ceiling effects limit how well the Berg Balance Scale can differentiate balance ability across the full spectrum of function. The scale has a finite range, so very impaired individuals often score near the bottom and very high-functioning individuals near the top. This clustering reduces sensitivity to small but meaningful changes at the extremes, meaning it’s not ideal for tracking progress in those groups. The scale does not measure cardiovascular endurance, and it is widely used in clinical settings, so labeling it inappropriate for clinical use isn’t accurate.
