The ability to maintain an upright position during quiet standing is a useful motor skill. The Sensory Organization Test (SOT) is a timed balance test that evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. The Fugl-Meyer Sensorimotor Assessment (FMSA) balance subscale is the functional status assessment that indicates amount of assistance needed during various balance tasks. Functional Independence Measure (FIM) is the functional status assessment tool and FIM can be used clinically as an outcome measure. The purpose of this study was to see if the SOT can be used as a evaluation tool to measure hemiplegic patients' balance ability. Thirty-six patients with hemiplegia participated in this study. SOT scores were significantly correlated with FMSA balance scores and FIM scores(p<0.05). However correlation coefficients were not so high (r=0.60, and r=0.51, respectively). Therefore, further study is needed to verify the SOT's usefulness when physical therapists are evaluating for hemiplegic patients' balance ability.
