Pelvic floor muscle training with and without functional electrical
stimulation as treatment for stress urinary incontinence
Background: Twelve to 55% of women experience stress
urinary incontinence at some time during their lifetime.
Objective: To compare the effectiveness of pelvic floor
muscle training with and without electrical stimulation in
treatment of stress urinary incontinence.
Material and Methods: Participants were 24 women,
27-73 years of age, diagnosed with stress urinary
incontinence. Exclusion criteria were pregnancy and urge
urinary incontinence. These participants were randomly
divided into group 1 and 2. Both groups trained 15 min.
twice a day for 9 weeks. Group 2 used simultaneously
intermittent electrical stimulation.
The pelvic floor muscles were evaluated using the
Oxford scale, vaginal palpation, and by electromyogram,
(Myomed 930, Enraf Nonius). The quantity and frequency
of urinary incontinence episodes was evaluated using
a questionnaire and a VAS scale before and after the
treatment.
Results: The groups were demographically similar,
except group 2 was significantly younger. Both groups
had significantly increased pelvic floor muscle strength
(p=0.007; p=0.005 respectively) after the treatment and
70% of all the women had reduced or no stress urinary
incontinence. Group 2 had significantly (p=0.013) better
relaxation post treatment.
Conclusion: Pelvic floor muscle training is an effective
treatment for stress urinary incontinence, but electrical
stimulation gave no additional effect for this patient group.
The significantly lower relaxation threshold in group 2
indicates that electrical stimulation could be a possible
treatment for symptoms caused by hypertensive pelvic
floor muscles.
