Current techniques in the evaluation of motility disorders

The understanding of motility disorders has been greatly improved since the introduction of reliable and non-invasive recording techniques. Motility can now be studied by measuring transit, motor activity, and electrophysiology in all regions of the gut. Barium studies, radiological screening, pH monitoring, cinematography, radio-telemetric recording, manometry, radionuclide scintigraphy, intubation, endoscopy, and gamma-camera scintiscanning are reviewed as are the uses of strain gauges, pressure inducers and non-absorbable carbohydrates.
