Student's t-tests for POST vs. PRE conditions of non-sEMG parameters (one-tailed, paired, N=13)

Parameter	PRE	POST	Difference	p-value
Strain	54.5 (23.0)	26.5 (21.3)	−28.0 (24.5)	0.001
/a/ Rise Time (ms)	112 (45)	111 (77)	−1 (89)	0.508
/i/ Rise Time (ms)	95 (27)	96 (33)	1 (41)	0.467
AP rating	2.4 (1.1)	2.1 (1.0)	−0.3 (0.7)	0.060
FVF rating	3.5 (0.8)	2.8 (0.9)	−0.7 (1.1)	0.020
AP quantitative	0.53 (0.41)	0.48 (0.22)	−0.05 (0.23)	0.212
FVF quantitative	3.92 (7.01)	3.65 (7.01)	−0.27 (0.64)	0.076
Airflow C (L/s)	0.36 (0.19)	0.23 (0.09)	−0.13 (0.19)	0.014
Airflow L (L/s)	0.53 (0.23)	0.30 (0.14)	−0.24 (0.30)	0.008

PRE = mean (standard deviation) pre-injection, POST = mean (standard deviation) post-injection, Difference = mean POST − PRE, C = comfortable, L = loud, AP = anterior-posterior, FVF = false vocal fold, p-values shown in bold indicate parameters found to be statistically significantly different POST relative to PRE at a p < 0.05 level.
