Participant will be prescribed with oral medication in combination with biofeedback-assisted pelvic floor muscle training (PFMT) for the first month. Participant will continue to have biofeedback assisted PFMT for another two months without oral medication. The investigators expected that combination therapy will improve the compliance and severity of symptoms in women with overactive bladder.
Medical treatment for overactive bladder is acceptable widely. However, the effect of drug treatment is different due to compliance and side effect of the drug. Biofeedback-assisted pelvic floor muscle training (PFMT) is the first line recommendation for overactive bladder. The slow effect of biofeedback-assisted pelvic floor muscle training leads to low motivation for continuous treatment and results in compliance difference. This slow effect also changes the degree of improvement in the treatment of overactive bladder. This study is designed to evaluate the efficacy of combination therapy for treatment of female overactive bladder.
