title: Is it possible to shorten examination time in posture control studies?
abstract: OBJECTIVE
  The sensory organization test (SOT) is the gold-standard test for the study of postural control with posturographic platforms. Three registers of Conditions 3, 4, 5 and 6 are conducted to find an arithmetic mean of the 3, with the time that this entails. The aim of this study was to determine whether a single record for each SOT condition would give us the same information as the arithmetic mean of the 3 recordings used until now.
  
  
  METHODS
  100 healthy individuals who performed a sensory organisation test in the Smart Balance Master(®) Neurocom platform. For the statistical analysis we used the Wilcoxon test for nonparametric variables and dependent t-student for paired samples for parametric variables (P<.05).
  
  
  RESULTS
  When comparing the scores on the first record with the average of the 3 records, we found statistically significant differences for the 4 conditions (P<0.05). Comparing the first record to the second record also yielded statistically significant differences in the 4 conditions (P<.05). Upon comparing the second record with the third, however, we found differences in only Condition 5, with the significance being borderline (P=.04). Finally, comparing the average of the first and second record with the average of the 3 records, we also found statistically significant differences for the 4 conditions (P<.05).
  
  
  CONCLUSIONS
  Using only 1 or 2 records from each of the conditions on the SOT does not give us the same information as the arithmetic average of the 3 records used until now.
