Vestibulo-ocular Reflex Gain Ratio
Time Frame: VOR measurements to determine gain were performed immediately before and after each approximately 30 minute training session. Pre- and post-training gains were then combined in the VOR gain ratio to determine the training effect.
|
The vestibulo-ocular reflex gain is the relationship between a rotation of the head and the evoked eye movement.
The outcome measure is the ratio of the VOR gain after training to that before training.
VOR gain is determined by a scaled fit of eye speed to evoking head speed (normal gain is 1).
Note that this experiment was not a treatment of impairment but a test of the ability of the vestibular game to elicit motor learning (away from normal) in individuals with intact motor learning.
In that context, an increase in the gain to a value greater than unity (faster eye movement relative to the head movement) is "better" with respect to the training goal, but it is not "better" with respect to real-world visual function, for which a gain of one is the goal.
There is no threshold value for this type of motor learning experiment.
Instead, the question is whether the gain is increased after training, and if so, by what percentage relative to the training goal.

Nausea Scale
Time Frame: Immediately after each 10-minute game block, median value calculated for each participant
|
Participants with vestibular hypofunction rated their nausea after each game block on a scale of 1 to 10.
For each visit, there were up to 3 game-blocks, each of 10-minutes duration.
The number of blocks was determined by the participant.
A higher score is a worse outcome (more nausea).
The average nausea scale rating was determined for each participant.
The final result is the median of these averaged scores.
