Abstract

The Star Excursion Balance Test (SEBT) is an eight-direction, maximal-reach balance test whose measurement properties are unknown in participants with chronic patellar instability. We designed an observational study with repeated measures to evaluate the test-retest reliability, cross-sectional and longitudinal construct validity, sensitivity to change and responsiveness of the SEBT in this population. Fifteen patients completed the SEBT and reported outcomes at baseline and two weeks and four patients completed testing three months later at the Fowler Kennedy Sports Medicine Clinic.

Intra-class correlation coefficients (ICC) for the SEBT were fair to good, ranging from 0.66-0.84. The SEBT demonstrates good cross-sectional construct validity and we are unable to comment with certainty on longitudinal construct validity; correlations between SEBT reach distance and patient-reported outcomes showed agreement with our hypotheses in 93 of 126 (74%) and 46 of 108 (43%) directions. These are preliminary results of a larger continuing study; therefore definitive conclusions cannot be made.
