Negative correlation between head mean amplitude and a perceptual abnormalities/hallucinations (P4) in SO and b disorganized communication (P5) in MR video were significant even after correction for multiple parisons (p < 0.004). Scores for each symptoms are expressed in Y-axis, while the X-axis represents the head mean amplitude (mean amplitude of motion across the entire video analysis) collected by motion energy analysis16.
