Figure 9: Maximum ROM measurements for all subjects in all equipment states. Subjects are denoted by color: subject 1 (S1) in blue, S2 in green, and S3 in red. The different equipment states are distinguished by marker symbol: crosses for the PT state, triangles for the UE state, and circles for the 1D state. The gaps in the graph are the result of data rejection due to marker disappearance and unauthorized movements of the torso during the testing procedure.
