Fig. 2From: Clustering trunk movements of children and adolescents with neurological gait disorders undergoing robot-assisted gait therapy: the functional ability determines if actuated pelvis movements are clinically usefulVisual description of trunk obliquities: To evaluate the kinematic behavior in the frontal plane, 3 axes were defined. The thorax axis by connecting the two shoulder joints (in green), the pelvis axis by connecting the two hip joints (in blue) and an axis parallel to gravity (in black). From these axes, Pelvis to World obliquity (A), Thorax to Pelvis obliquity (B) and Thorax to World obliquity (C) were calculatedBack to article page
