significant after comparison by the Bonferroni inequality
method (Fig. 3).
Table 4 shows changes from baseline to 2 and 4 weeks in
the control group, the good-adherence group (upper 25%
subdivision: practiced 6 or more over 2 weeks), and the poor
adherence group (under 25% subdivision: practiced 1–5
times over 2 weeks). Excluded were 7 intervention participants
who did not report how many days they practiced and
12 intervention participants who withdrew from this study
at 2 weeks only as indicated in Table 4.
Table 4 shows that low back pain gradually decreased in
the good-adherence group after 2 weeks ( p = 0.006) and 4
weeks ( p = 0.001). Each group difference between the 3
groups was estimated using the Bonferroni method. After 2
weeks, the good-adherence group decreased back pain
compared with the poor-adherence group ( p = 0.005). The
control group also decreased back pain ( p = 0.028). After 4
weeks, the good-adherence group decreased back pain
compared with the control ( p = 0.034) and poor-adherence
groups ( p = 0.010). Moreover, menstrual pain was signifi-
cantly reduced in the good-adherence group ( p = 0.044). In
the post hoc test, the good-adherence group decreased menstrual
pain compared with the control group at 4 weeks
( p = 0.028).
