Home Biofeedback Treatment: After getting advice on standard treatment and breathing exercises, patients will be taught how to use the home-trainer in a single lab session. Then the investigators will place a reusable, dual sensor, probe into their rectum. The probe is connected to a hand- held pressure monitor displaying the patient's response (Anatoner, Protech, Hyderabad, India). Next, the clothed patient will be asked to sit on a commode, and attempt 15 bearing down maneuvers. When the anal sphincter pressure decreases more lights go on. If the patient cannot relax then fewer lights go on. Thus, the number of lighted lights gives instant feedback about their performance. Patients will get a 20-minute tape recording for home use. Patients will be asked to insert the probe at least twice daily and each time practice at least 15 bearing down maneuvers; a daily log will be kept. At 4 and 8 weeks, they will return for follow up. Based on their progress, new targets will be set by adjusting the device's sensitivity. After 3-months, they will have a colonic transit, anorectal manometry and fecom expulsion study. Progress will be monitored through bi-weekly phone calls.
