Why biofeedback would help this problem: The pelvic floor muscles do not behave normally when vulvar vestibulitis is present. There are more spasm and abnormal levels of tension. Psychophysiological recording techniques can record these patterns of muscle tension. Muscle tension biofeedback is used to show these patterns to the patient so she can learn to recognize when patterns become abnormal and to normalize them. When the patterns of muscle activity become normal, symptoms are significantly reduced or eliminated.
