As a quantitative measure of the amount of correction, I computed the proportion of the initial direction error corrected by each hand.
Since our study evaluated ANB change as a measure of AP correction, we were able to focus exclusively on skeletal position instead of tooth position.
The time point at which the mean trajectory first exceeded 25% of the distance necessary to fully compensate for the perturbation was used as temporal measure of the correction onset (TpPath25; Fig. 1 c, d ; Reichenbach et al. 2009).
The idea behind this measure is comparing the amount of corrections a user needs to perform when using an interactive system (CTint) to a manual correction (CTman).
Moreover, the dual-diode scheme provides a measure of self-correction, since both front and rear diode channels are subject to the same changes in temperature.
Additional parameters available included R0 and Rinf obtained from the modelling curve-fitting procedure and T d, a measure of the model correction [ 22] required to account for deviation of the data from the fitting model [ 29] due to measurement artefacts referred to above.
Indeed, it is unknown how well either of these measures correlates with correction of the basic ion transport defect or with markers of clinical improvement.
The impact of asynchronism on patients' prognosis and the availability of correction measures require further investigation.
Effects of Age and Gender were not significant for any measure after correction for multiple comparisons.
Another recent report compared two methods of correction of measured esophageal pressure and found that correcting esophageal pressure measurements obtained at relaxation volume of the respiratory system is more accurate than using the 5 cm H2O offset to account for the weight of mediastinal structures [ 17].
Many authors determine the disc height to measure the achievement and loss of correction [ 16, 36], but the shape of cervical vertebral bodies is, in contrast to the thoracal spine, not consistently rectangular.
