Diagnosis is by rectal examination. A specialized tool called a "Perineocaliper" can be used to measure the descent of the<unk> . A retro anal ultrasound scan may demonstrate the condition. "Anti sagging tests", whereby the abnormal descent is corrected temporarily, may help to show whether symptoms are due to<unk>  or are in fact due to another condition. Normally, the anal margin lies just below a line drawn between the coccyx (tailbone) and the pubic symphysis. In<unk>  the anal canal is situated several cm below this imaginary line, or it descends 3–4 cm during straining. Defecography may also demonstrate abnormal perineal descent.
