The average power in frequency region is the percentage of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (baseline refers to the test performed during screening, not the baseline value of the EGG test) in percent of time with frequencies in the ranges, where positive values for normal rates indicate an increase in the normal pacing (improvement).

Electrogastrography (EGG) is a test which records the electrical pacemaking signals that travel through the stomach muscles and control the muscles' contractions. Normal pacing is considered 2.5-3.7 cycles per minute (cpm). Tachygastria is when the rate of electrical activity in the stomach is 3.8-10 cycles per minute for at least 1 minute (an increase in electrical activity in the stomach). The average power in frequency region is the percentage of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (here, baseline refers to the test performed during screening, not the baseline value of the EGG test) in percent of time with frequencies in the ranges, where negative values for tachygastria indicate improvement (less time in a dysrhythmic state).

Electrogastrography (EGG) is a test which records the electrical pacemaking signals that travel through the stomach muscles and control the muscles' contractions. The 0-30 post-satiety measurement that taken 30 minutes after the participant consumes Ensure until feeling completely full. Normal pacing is considered 2.5-3.7 cycles per minute (cpm). Tachygastria is when the rate of electrical activity in the stomach is 3.8-10 cycles per minute for at least 1 minute (an increase in electrical activity in the stomach).

Electrogastrography (EGG) is a test which records the electrical pacemaking signals that travel through the stomach muscles and control the muscles' contractions. Normal pacing is considered 2.5-3.7 cycles per minute (cpm). Duodenal is when the rate of electrical activity in the stomach is >10-15 cycles per minute for at least 1 minute. The average power in frequency region is the percentage of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (here, baseline refers to the test performed during screening, not the baseline value of the EGG test) in percent of time with frequencies in the ranges, where negative values for duodenal indicate improvement (less time in a dysrhythmic state).
