Behavioral interventions for overactive bladder (OAB) include bladder training and behavioral training. Bladder training focuses on modifying bladder function by changing voiding habits; a bladder diary is indispensable. Behavioral training focuses on improving voluntary control rather than bladder function. It works through modification of the bladder outlet using methods, such as pelvic floor muscle training and urge suppression strategies to inhibit detrusor (bladder) muscle contraction. Behavioral methods--with biofeedback (which requires instrumentation), verbal feedback during a pelvic examination (using vaginal or anal palpation), or electrical stimulation--appear to be at least as effective in terms of reducing incontinence episodes as currently available drug therapy. However, evidence suggests that combining behavioral and drug therapy may produce better results than either approach alone. More research is needed to elucidate the role of behavioral modification in reducing urgency, frequency, and nocturia.
