Statistical analysis comparing the task completion times and total distance between the first and fourth trials
Task | 1st trial time, mean (range) (sec) | 4th trial time (mean, range) (sec) | P value | 1st trial total distance (mean, range) (cm) | 4th trial total distance (mean, range) (cm) | P value |
---|---|---|---|---|---|---|
Tonsil | 97 (67–180) | 36 (26–48) | < 0.001 | 11.5 (4.0–21.6) | 5.5 (2.3–8.9) | 0.002 |
Epiglottis | 99 (36–187) | 45 (27–62) | 0.001 | 10.6 (6.2–26.1) | 7.4 (5.1–11.3) | 0.14 |
Vocal Process | 185 (60–596) | 65 (49–92) | 0.01 | 29.0 (11.8–85.5) | 12.6 (8.3–19.7) | 0.04 |
Interarytenoid | 95 (54–221) | 58 (43–71) | 0.02 | 13.6 (6.5–40.6) | 11.2 (6.2–27.3) | 0.33 |
In all tasks there was a statistically significant improvement in time and distance, except for the distance calculations for the epiglottis and interarytenoid tasks. Although not significant, there was still a numerical decrease in the means for these two tasks and a significantly shorter completion time
This still implies that there was an increase in velocity and efficiency for these tasks
