  Abstract Objective: We aimed to study the kinematic indices of the pelvic floor, anorectal angle and the descent of perinea, and the differing movement, in dyssynergic defecation patients in comparison with healthy controls, based on MR defecography. Methods: Twenty-two individuals involved with dyssynergic defecation constipation and fourteen healthy asymptomatic subjects fell into this study. In four dynamic pelvic floor MRI indices, namely paradox (unusual change of anorectal angle), perineal descent during straining, perineal ascent, and narrowing of anorectal angle at squeeze, were measured in patients and healthy subjects. Results: Paradox Index had the highest sensitivity (95.45%) and specificity (92.86%) for detection of dyssynergic defecation, with an R2 value of near 1 (0.902). The sensitivity and specificity of other indices were not high; therefore, no significant improvem.. View More»
