Comparison of objective head movement kinematics of patients 6 weeks following the surgery with their pre-op state. (a) Each column corresponds to a kinematic measure, while rows indicated FGA tasks. Dark circles show decreased measure 6 weeks after the surgery. The radius of the circle indicates the level of significance of the difference between the two groups. Orange box indicates the FGA task in which patients altered their kinematics the most from pre-op and sub-acute patients (b) The normalized value of all kinematic measures for patients across all time points during more informative tasks of the FGA: ‘gait with horizontal head turns’ (task 3). Green, red, and blue lines correspond to pre-op, sub-acute post-op, and chronic post-op patients. Asterisks denote the kinematic measures that were significantly different between pre-op and sub-acute post-op patients.
