The four square step test in children with Down syndrome: Reliability and concurrent validity.

Verma A, Samuel AJ, Aranha VP - J Pediatr Neurosci (2014 Sep-Dec)

Bottom Line: FRT was used as the criterion dynamic balance measure to validate FSST.The Bland-Altman limits of agreement were also satisfied.Concurrent validity between FRT and FSST with Spearman's ρ = -0.58 (-0.86 to -0.13).

ABSTRACT

Purpose: To estimate test-retest reliability, inter-rater reliability and validation of a method for measuring balance by stepping over four squares, four square step test (FSST) in children with Down syndrome (DS).

Methods: A sample of 13 children with DS was recruited for the cross-sectional study. They were asked to perform FSST and the time taken was noted. For estimating test-retest reliability, FSST was done by principal investigator twice and Inter-rater reliability was assessed by principal investigator and second investigator with an interval of 7 days. FRT was used as the criterion dynamic balance measure to validate FSST. The data was tabulated and analysed statistically.

Results: The test-retest reliability and inter-rater reliability of FSST are ICC(1,1) = 0.70 (0.64-0.90) and ICC(2,1) = 0.78 (0.62-0.91) respectively. The Bland-Altman limits of agreement were also satisfied. Concurrent validity between FRT and FSST with Spearman's ρ = -0.58 (-0.86 to -0.13).

Conclusion: FSST has moderate to good concurrent validity and good reliability among the children with Down syndrome.

Figure 6: The Bland-Altman graph shows LOA of repeated measurements by the principal investigator and second investigator

Mentions: The Bland-Altman limits of agreement plots are included in Figures 5 and 6. The LOA between repeated measurement fall well within 2 SD. In both the figures, there is one outlier. Thus the agreement between measurements was satisfied.
