NEW YORK (Reuters Health) - Biofeedback training can be useful people with a type of chronic constipation characterized by excessive straining, paradoxical anal contraction, and impaired propulsion of stool from the rectum -- what doctors call "dyssynergic defecation."
"Dyssynergic defecation," Dr. Satish S. C. Rao told Reuters Health, "is a common subtype of chronic constipation that leads to persistent difficulty with defecation and is poorly recognized by most physicians. Most of these patients will fail laxative treatment in the long term."
About a third of people with chronic constipation seen in specialized centers have this type of constipation, Rao of the University of Iowa Carver College of Medicine in Iowa City and colleagues note in a report.
They conducted a study to see if the condition could be relieved by biofeedback focusing on anal muscle relaxation and coordination and simulated defecation training.
