Abstract: | Purpose] The purpose of this study was to devise a new urinary incontinence exercise
using co-contraction of both the transverse abdominal muscle (TA) and pelvic floor muscle
(PFM) and examine the intervention effect in middle-aged women with stress urinary
incontinence (SUI). Subjects] The subjects were fifteen women with SUI who were divided
into two groups: the TA and PFM co-contraction exercise group (n=9) and the control group
(n=6). Methods] Participants in the exercise group performed TA and PFM co-contraction
exercise. The thickness of the TA was measured before and after 8 weeks of exercise using
ultrasound. The thickness of the TA was measured under 4 conditions: (1) at rest, (2)
maximal contraction of the TA, (3) maximal contraction of the PFM, and (4) maximal
co-contraction of both the TA and PFM. Results] There were no significant differences
among the results of the control group. In the exercise group, the cure rate of SUI was
88.9% after the intervention. There were significant differences in the thickness of the
TA during maximal co-contraction of both the TA and PFM after the intervention.
Conclusion] The TA and PFM co-contraction exercise intervention increases the thickness
of the TA and may be recommended to improve SUI in middle-aged women.Key words: Stress urinary incontinence, Transverse abdominal muscle, Exercise |
