[Purpose] This study investigated the intra-rater, inter-rater and test-retestreliability of the sideways step test (SST), its correlation with other indicators ofstroke-specific impairment, and the cut-off count best discriminating subjects with strokefrom their healthy counterparts. [Subjects and Methods] Forty-three subjects with chronicstroke and 41 healthy subjects older than 50 years participated in this study. The SST wasadministered along with the Fugl-Meyer motor assessment for the lower extremities(FMA-LE), the five-times sit to stand (5TSTS) test, the Berg Balance Scale (BBS), themovement velocity (MVL) by the limits of stability (LOS) test, the ten-metre walk (10mW)test, the timed “Up and Go” (TUG) test and the Activities-specific Balance Confidence(ABC) scale. [Results] The SST showed good to excellent intra-rater, inter-rater andtest-retest reliability. The SST counts correlated with 5TSTS times, 10mW times, TUGtimes, and the FMA-LE and BBS scores. SST counts of 11 for the paretic leg and 14 for thenon-paretic leg were found to distinguish the healthy adults from subjects with stroke.[Conclusion] The sideways step test is a reliable clinical test, which correlates with thefunctional strength, gait speed, and functional balance of people with chronic stroke.Key words: Balance, Stroke, Rehabilitation |
