Comments/Special Instructions
The Berg Balance Scale (BBS) was developed to measure balance among stroke patients and older people with impairment in balance function by assessing the performance of functional tasks. It is a valid instrument used for evaluation of the effectiveness of interventions and for quantitative descriptions of function in clinical practice and research. This test has been validated for use in individuals with SCI, and has the advantage of being valuable for other neurologic populations.
Pediatric Balance Scale, has been evaluated in children age 5–15 with known balance impairments. Shows good test-retest and inter-rater reliability. Child must be able to follow directions. It has not been evaluated specifically for children with SCI.
A study by Conradsson and colleagues (2007) demonstrated that a change of 8 BBS points is required to reveal a genuine change in function between two assessments among older people who are dependent in ADL and living in residential care facilities. The BBS is appropriate for community dwelling elderly people, individuals that have suffered a stroke, and the elderly population with balance difficulties.
Administration takes approximately 15–20 minutes.
Scoring and Psychometric Properties
Scoring: A five-point scale, ranging from 0–4. "0" indicates the lowest level of function and "4" the highest level of function. Total Score = 0–56. Score of 41–56 = low fall risk, 21–40 = medium fall risk, 0–20 = high fall risk.
Psychometric Properties: Overall, the BBS appears to be a reliable tool used to measure outcomes. Berg et al demonstrated that the inter-rater reliability ICC was .99. The BBS may have a ceiling effect, and is insensitive to individuals with very high levels of balance.
