Biofeedback
Electromyographic (EMG) activity was recorded from sensors placed in the anal canal, averaged, and displayed to patients to help them learn to relax the pelvic floor muscles during straining.
Electrogalvanic stimulation
Electrical stimulation was applied to pelvic floor muscles through an anal plug. Frequency was 80 pulses per sec, and voltage was slowly increased from 0 to 150-350 volts as tolerated.
Digital massage
Using a gloved finger, the therapist pressed on the levator ani as firmly as tolerated and moved the finger from side to side 3-4 times.
