Article Title: Anal sphincter function in rectal intussusception and high and low "take-off" external rectal prolapse-A prospective observational study.
Article Snippet: A digital signal processor (ED- 1932; Knowles Electronics, IL, USA) transmits wide- band sound waves into the bag with the reflected acoustic impulses used to calculate the CSA [22] whilst pressure is simultaneously recorded by a transducer (SX30D, Sensym sensor systems).

Article Title: Baseline Anal Sphincter Elastance May Predict Long-Term Outcomes of Sacral Neuromodulation for Fecal Incontinence.
Article Snippet: A digital signal processor [ED-1932; Knowles Electronics, IL, USA] transmits wide-band sound waves into the bag with the reflected acoustic impulses recorded by a microphone and used to calculate the CSA by applying the Ware-Aki algorithm.20 In combination with a pressure pump [ED-1932; Knowles Electronics, IL, USA], the bag is inflated from 0 to 100 cmH20 in increments of 5 cmH20 following which there is a 3 s pause to allow calculation of the CSA at rest.

Article Title: Provocative tests of anal sphincter function correlate with symptoms and subtypes of faecal incontinence
Article Snippet: Using a digital signal processor (ED-1932; Knowles Electronics, Illinois, USA), sound waves are transmitted into the bag, and the reflected acoustic impulses are recorded and used to calculate the CSA along the length of the anal canal.

Article Title: Continuous vs stepwise anal acoustic reflectometry: An improved technique for physiological measurement of anal sphincter function?
Article Snippet: Correspondence Nick Heywood, Department of General Surgery, Manchester University NHS Foundation Trust, Southmoor Road, Manchester M23 9LT, UK.. Email: nick.heywood@nhs.net Abstract Background: Anal acoustic reflectometry (AAR) is a technique for measuring the physiological profile of the anal canal, primarily the internal anal sphincter.. Evaluation of a new continuous method, recently developed for the urethra, would enable its future application for investigation of rectal reflexes.
