Figure 5From: Estimation of pelvis kinematics in level walking based on a single inertial sensor positioned close to the sacrum: validation on healthy subjects with stereophotogrammetric system F4A versus GA: angular ranges comparison. Direct estimated angular ranges from F4A (blue crosses) and GA (red crosses) separately for each of the three collected trials, in one representative subject. The average over the three is superimposed (horizontal line segment; blue and red for F4A and GA). This plot is replicated for each of the three angles (columns) and each of the three walking speeds (rows).Back to article page
