Background and Purpose: The Activities-specific Balance Confidence (ABC) Scale is recommended as the primary outcome measure to measure and track changes in balance confidence for individuals with neurological conditions. However, there is a lack of psychometric data when used for individuals with traumatic brain injury (TBI). The purpose of this study was to determine if the ABC Scale is correlated with performance-based measures of balance and walking, if the ABC Scale is reliable with repeated administration, and if the ABC Scale can identify individuals at risk for falls or near-falls.
