Coordination Pattern of the Thigh, Pelvic, and Lumbar Movements during the Gait of Patients with Hip Osteoarthritis

Figure 3

The time series data showing the mean coupling angle and coupling angle variability at lumbar/pelvic and pelvic/thigh segments about each directional movement. The mean coupling angle and coupling angle variability at lumbar/pelvic regions about lateral tilt (a), anterior/posterior tilt (b), and rotation movement, (c) and that at the pelvic/thigh regions about lateral tilt (d), anterior/posterior tilt (e), and rotation movement (f). The gray circle indicates the mean coupling angle of the control group. The white triangle indicates the mean coupling angle of the hip OA group. The gray line indicates the coupling angle variability within the hip OA group. The black line indicates the coupling angle variability within the control group.
