In addition, the parental ratings and movement ratings verified differences between the ADHD and control subsamples.
Mean ratings and absolute differences between patients' and physiotherapists' ratings are provided in Table 2. Using the rank-transformed dependent variables in the analyses lead to the same conclusions than with the untransformed variables in all models, except for the relationship between patient-physiotherapist agreement on pain intensity and changes in functional limitations at follow-up.
An ANOVA was performed on the quality scores to detect the significant variations in ratings: a difference between the extreme levels of audio quality (La1 and La7) was found for the video level Lv3 and an almost significant difference for Lv7, with a maximal difference of 0.35 MOS.
Similarly, for arousal ratings no difference between groups, F 1,30) =.27, p =.61, no main effect of Time, F 1,31) =.05, p =.82, or interaction of Time × Group, F 1,31) =.32, p =.58, was observed, while the covariate (rating at t2) was again significant, F 1,30) = 16.05, p <.0001, indicating that high ratings at t2 also led to higher ratings at t3 and t4.
Pain ratings revealed no differences between groups suggesting that although stimulation intensities were reduced in FMS, a comparable subjective pain sensation was elicited as in healthy control subjects.
The results of the single evaluation showed small differences between observer ratings as only 2 of the 40 images were inconsistently graded, i.e., the same image was ranked good by one observer and poor by another.
We completed the regression analysis of blood flow changes elicited by STN stimulation against emotional impacts ratings, equal to the difference between ratings of pleasant images and ratings of unpleasant images, on a scale from −3 to +3 in the seven subjects.
For both ANOVAS, post hoc pair-wise comparisons revealed significant differences between ratings of graphic and suffering stimuli, as well as between ratings of suffering and symbolic stimuli (all p<0.01).
The amount and direction of change occurring in the ratings between the rounds was assessed by summarising the differences between median ratings and absolute differences between median ratings.
All respondents rated the RLOs as excellent or good and there were no significant differences between ratings of University of Nottingham and non-Nottingham respondents (Wilcoxon paired p > 0.05).
