Illustration of the splint conditions.
a) Neutral b) Centric, c) DPS, d) Max. A detailed description of the splints is provided in the text.
Fig 2.
All trials of all conditions were subjected to a cluster analysis. The colour code for the three different categories is plotted in the legend. A: Distance matrix between each trial. Trials are plotted in the x and y direction. The colour of the image gives the distance between two trials. The contribution of the trials to subject, condition or side is colour coded in the legend underneath the image. B: Dendogram to visualize the similar characteristics of different trials. The trials on the x-axis are organized depending on the distance between them. The distance on the y axis is a measure for the number of steps required to combine sets of trials. C Loading rate of subjects (C1), conditions (C2), and subject, condition and side (C3). The rate is a value between 0 and 1 depending if no trial is loaded in a cluster or all trials are loaded in the same cluster.
Fig 3.
A: Distance matrix between subjects. The grey values indicate the distance between subjects. The red squares indicate the 11 comparisons that were not significantly classified. For the 4 subjects indicated by the green squares (two subjects are combined in every square) the projection on the discriminant was calculated and plotted in the graph B. B: Trials of the same subject were indicated by subject specific colour of the outer circle. The colours of the 4 subjects were green (10), red (14), magenta (4) and blue (15). The trials of the same condition were colour coded in the inner circle. The colour for the condition is given in the legend.

Subject specific differences of the movement pattern between the conditions.
A: Main contributions to the discriminant between different conditions and subjects. B: One example: Discriminant (blue line) between neutral and centric for subject 4, the highest contributions to the classification of the two conditions are indicated by the grey area. C: Movement pattern of the neutral (black) and centric (cyan) condition.
Fig 5.
Symmetry index of the different conditions.
The bars on the top indicate the significant differences between the four groups. The three interventions are more symmetric than the neutral condition, but no intervention is more symmetric than another intervention.
