Comparison of objective head movement kinematics between (a) pre-op (b) sub-acute post-op (c) chronic post-op patients and healthy controls during FGA tasks (1–4,6,8–10). (a–c) Each row corresponds to one of the FGA tasks, while columns correspond to kinematic measures that are associated with one of four main categories; (1) speed, (2) asymmetry, (3) variability, and (4) range of motion. The circles demonstrate the kinematic measures in each task that distinguish patients from healthy controls. Dark circles show decreased measure in patients, while the white circle means that measure was decreased in the healthy group. The radius of the circle indicates the level of significance of the difference between the two groups. Open red squares denote the differences with the healthy subjects that are common in patients across all time points. Open black diamonds show the differences that are common only across two post-op time points. Blue, green, and red arrows highlight specific kinematic measures that were most informative across all FGA tasks.
