Table 4.

TMD scores after stress loading (pre- and post-intervention).

	Placebo		SNK-L			SNK-H
	Mean	SD	Mean	SD	p-Value (vs. Placebo)	Mean	SD	p-Value (vs. Placebo)
Pre-intervention	52.09	10.88	52.32	7.69	0.9387	52.50	10.46	0.8925
Post-intervention	52.32	11.89	48.77	7.34	0.0472 *	48.55	9.51	0.0338 *
Variation	0.23	6.28	−3.55	6.72	0.0472 *	−3.95	6.15	0.0338 *

Data are expressed as mean ± SD. Between-group comparisons of pre-intervention values were performed using ANOVA. Between-group comparisons of post-intervention values and variations were performed using ANCOVA, with the pre-intervention value as a factor (*, p < 0.05; Placebo vs. SNK-L; Placebo vs. SNK-H).
