Validity (Pearson r) of the instrumented modified Clinical Test for the Sensory Interaction on Balance (i-mCTSIB) with Sensory Organization Test (SOT) using accelerometer data in anterior-posterior (AP) direction. Mean, range, and standard deviation presented. Correlations significant at p ˂ .05 (2-tailed) represented in bold. Validity of i-mCTSIB Composite score was similar when correlated to SOT Composite scores calculated with all 6 conditions and modified Composite scores with conditions 1, 2, 4 and 5.
