Characterizing Patients with Unilateral Vestibular Hypofunction Using Kinematic Variability and Local Dynamic Stability during Treadmill Walking

Figure 1

Location of the 34 anatomic markers and defined direction of movements used in this study. The trunk segment was represented by marker 6 (first thoracic vertebrae, T1), marker 7, and marker 8. The hip segment was represented by marker 19, marker 20 (anterior superior iliac spine, ASIS), and marker 22. The positive x-axis is the direction of walking, the positive y-axis is the left direction, and the positive z-axis is upward.
