Outcome Measures
Primary Outcomes (1)
Mean Percent (Prototype / Baseline) Time
The outcome measure for each subject is the mean of the (Prototype Time / Baseline Time) across 12 trials. The outcome measure for the experiment is the mean of 24 individual subject mean scores. This mean outcome measure is expressed as a percentage of the mean Baseline Time, where improved performance is represented by a percentage that is less than 100 percent of the Baseline Time. The lower the percentage, the better the performance improvement.
