Statistical analysis comparing the task completion times and total distance between the fourth and fifth trials with a 4-month time gap between the two trials

Task	4th trial total time, mean (range) (sec)	5th trial total time, mean (range) (sec)	P value	4th trial total distance, mean (range) (cm)	5th trial distance time, mean (range) (cm)	P value	4th trial speed, mean (range) (cm/s)	5th trial speed, mean (range) (cm/s)	P value
Tonsil	37 (26–48)	38 (25–55)	0.73	5.9 (2.9–8.9)	6.7 (2.2–9.6)	0.39	0.49 (0.29–0.81)	0.64 (0.17–0.97)	0.19

Vocal Process	65 (53–80)	57 (38–95)	0.27	13.0 (9.2–16.5)	11.1 (7.2–16.8)	0.20	0.29 (0.19–0.45)	0.38 (0.30–0.51)	0.0007
Interarytenoid	60 (43–71)	45 (28–57)	0.002	11.1 (6.8–19.8)	9.75 (5.5–13)	0.37	0.27 (0.16–0.41)	0.36 (0.30–0.46)	0.02

The majority of the tasks did not show a statistically significant difference in efficiency of operating the FLEX™ System, and all the statistically significant results showed an improvement in task completion time and distance traveled
