Abstract: The Sensory Organization Test (SOT) is an objective computer-based test used to quantitatively assess an individual’s ability to use visual, proprioceptive, and vestibular cues to maintain postural stability. The objective of this study was to determine the reliability of the SOT to differentiate fallers as compared to non-fallers in individuals with PD. This was a non-randomized single site controlled trial in a clinical setting. 39 subjects with PD (age 70.8 ± 9.9) were identified as fallers or non-fallers based on a history of two or more falls in the past six months. Balance was evaluated using the SOT, Mini-BESTest and MDS-UPDRS-III. Composite scores from the SOT, Mini-BESTest and MDS-UPDRS III were analyzed. There was a statistically significant difference in the mean Mini-BESTest score of 17.8 ± 5.6 for fallers compared to 24.8 ± 2.3 for nonfallers (p<0.05). There was a statistically significant difference in the mean SOT score of 61.8 ± 14.4 compared to 71.8 ± 9.4 for nonfallers (p<0.05). The mean MDS-UPDRS-III score for fallers was 33.6 ±11.6 and 27.8± 9.2 for nonfallers, this was not significant. An ROC curve was constructed to determine the optimal cut-off score for determining a high-risk faller with PD. Our data suggests the SOT is a reliable test to identify PD subjects at risk for falling with a cut-off score of < 67.
