Table 4.

Repeated-measures ANOVA with post hoc comparing the pain intensity of Groups A and B at pretreatment, 2^nd week, and 4^th week sessions (N = 26).^a

Variables	Mean ± SD		f	p
	Group A (13)	Group B (13)
Pretreatment	7.63 ± 2.98a	7.75 ± 0.96a
2nd wk	4.83 ± 0.75b	6.25 ± 0.95c	31.240	0.003*
4th wk	2.66 ± 0.81d	4.67 ± 0.81e

^*Significant at p < 0.05.

ANOVA = analysis of variance; SD = standard deviation.

^aPost hoc Tukey’s highest significant difference. Superscript letters within the table: mean mode with the same superscript letters indicate no significant difference between means. Mean mode with different superscript letters indicate significant difference.
