Bootstrapped analysis of variance results showed significant differences in the mean change scores between the REHACOP group and control group in processing speed ( 0.13 [ SE = 0.07 ] vs -0.15 [ SE = 0.09 ] , p = 0.025 ) , visual memory ( 0.10 [ SE = 0.10 ] vs -0.24 [ SE = 0.09 ] , p = 0.011 ) , theory of mind ( 1.00 [ SE = 0.37 ] vs -0.27 [ SE = 0.29 ] , p = 0.013 ) , and functional disability ( -5.15 [ SE = 1.35 ] vs 0.53 [ SE = 1.49 ] , p = 0.012 ) .
