Participants were randomly assigned to either the gaze-stabilization (GS) exercise group, or the habituation (H) exercise group using a program that generated a randomized block assignment to group based on the order in which the participant was enrolled in the study. The participants in the GS group performed a series of exercises designed to improve gaze-stability during head movements (Table 1) as well as balance and gait exercises. The participants in the H group performed a series of exercises designed to decrease their sensitivity to head movements (Table 1), as well as balance and gait exercises similar to those performed by the GS group. The exercises used in each group are used routinely in clinical practice and are often referred to as either adaptation exercises (the GS group), or habituation exercises (the H group). The participants were instructed to perform the exercises three times a day over a 6-week period. The participants returned to the lab once a week for clinical assessment and progression of the exercise program. The exercise progression was based on clinical experience treating patients with acute and subacu
