Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The SmartPill GI Monitoring System offers an alternative non-invasive method for characterizing disorders of the stomach. The system consists of an ingestible capsule that houses sensors for pH, temperature, and pressure, a receiver for receiving and storing signals from the capsule, and software for displaying data on a personal computer. The capsule samples at regular intervals and transmits the sensed pH, pressure, and temperature data to a portable receiver worn by the subject. After test completion, the recorded data is downloaded to a personal computer for subsequent evaluation. This trial is for subjects 65 years of age and older.
