Reliability and Validity of the Standing Balance Assessment for Spinal Cord Injury (SBASCI)
Keywords:Spinal cord injury, standing balance, Validity, Reliability
Background: Standing balance has been reported as one of the major determinants of walking in Spinal
Cord Injury (SCI). Standing Balance Assessment for Spinal Cord Injury (SBASCI) is a newly developed
tool to assess standing balance in individuals with SCI which uses gradations of physical assistance and
devices required to achieve standing. The purpose of the study was to establish interrater reliability and
concurrent validity of SBASCI.
Method: 39 individuals with SCI were part of the study. Interrater reliability was established by correlating
the scores of two raters using kappa statistics. Concurrent validity was evaluated by comparing scores
between SBASCI and Berg Balance Scale.
Results: Inter rater reliability showed excellent value of 0.98 using Cohen’s coefficient. The inter rater
reliability for all the items of SBASCI ranged with a cohen’s kappa coefficient form 0.37 to 0.97 (ICC
0.68 to 1.00) suggesting fair to excellent reliability. The concurrent validity shows estimated correlation
(r=0.9376) at 95% confidence interval and was statistically significant (p<0.05)
Conclusion: The study established the psychometric properties of SBASCI and supported its concurrent
validity and interrater reliability as a useful instrument to measure Standing Balance of individuals with
Spinal Cord Injury.
