A physical therapist evaluates standing balance in a patient with T10 AIS D SCI using a 14-item performance-based scale scored from 0 to 56. However, the therapist notes this measure has potential floor/ceiling effects in SCI and was not developed specifically for this population. Which outcome measure is being used?

However, the therapist notes this measure has potential floor/ceiling effects in SCI and was not developed specifically for this population. Which outcome measure is being used?

• A. ABLE Scale
• B. Neuromuscular Recovery Scale (NRS)
• C. WISCI II
• D. Berg Balance Scale (BBS)

Answer: (D)

The important idea here is measurement sensitivity and how well a tool fits the population. A balance measure that isn’t tailored to people with spinal cord injury can fail to distinguish between real differences in function, especially if many patients cluster at the top or bottom of the scale—that’s what floor or ceiling effects are. The Berg Balance Scale matches the description: it has 14 items and a total score ranging from 0 to 56. It was developed for older adults with balance impairment and later found to be less than ideal for SCI populations because it isn’t specific to the balance demands or limitations seen after spinal cord injury. In SCI, you can easily hit the ceiling with some tasks or reach the floor with others, limiting the scale’s ability to detect changes in standing balance over time. While it is simple and widely used, its lack of SCI specificity and susceptibility to floor/ceiling effects make it a less ideal choice for measuring standing balance in this population, hence why, in this scenario, a different measure would typically be considered more appropriate.
