Other tests can help with the evaluation of motility disorders, including upper gastrointestinal X-rays, gastric emptying studies, and electrogastrograms.
The most recent device for determining gastrointestinal motility is a radiotelemetry capsule (Smartpill) that senses both the pH and the pressure generated when the stomach or intestinal muscles contract around it. The capsule is swallowed, and it then travels through the stomach and intestines. While it is traveling, it continually senses the pressure around it and transmits this information wirelessly to a receiver worn on the outside of the body. Later, the data is downloaded from the recorder and analyzed.
