- English language proficiency
- Willingness to be videotaped and connected to physiologic monitoring devices during the visit
Exclusion Criteria:
- Diagnosis of Crohn's disease, systemic sclerosis, known active ulcer disease, gastric cancer, or untreated/active Barrett's esophagitis based on subject self-report and/or medical record review

Association of Change in Patient's GSR From Beginning to End of Study Visit With GERD Symptom Severity 2 Weeks Later
Periodo de tiempo: Beginning to end of study visit (1 hour or less for change in GSR)
|
Galvanic skin response (GSR) was measured with a device from ADInstruments during the baseline study visit.
Values ranged from 0.93 - 12 micro-Siemens (μS).
Change in GSR was calculated as mean value of GSR for the first 2 minutes of the study visit minus mean value of GSR for the last 2 minutes of the study visit.

Beginning to end of study visit (1 hour or less for change in GSR)

Association of Change in Patient's High Frequency HRV From Beginning to End of Study Visit With GERD Symptom Severity 2 Weeks Later
Periodo de tiempo: Beginning to end of study visit (1 hour or less for change in HRV/RMSSD)
|
Heart rate variability (HRV) was measured using a device from ADInstruments gathering data at 256 Hz.
We used the RMSSD (Root Mean Square of the Successive Differences) value as a proxy for high frequency HRV.
Measured values ranged from 0 - 150 msec.
Change in high frequency HRV was calculated as the RMSSD value for the first 5 minutes of the study visit minus the RMSSD value for the last 5 minutes of the study visit.

Correlation Between Concordance in GSR Between Patient and Physician During the Study Visit and Percent Change in Patients' GERD Symptoms Over 2 Weeks
Periodo de tiempo: Beginning to end of study visit (1 hour or less for concordance between patient and physician GSR)
|
Concordance in galvanic skin response (GSR) between patient and physician was calculated using an established approach (Marci CD, 2007; PMID 17299296) to create a single index value for the visit.
The natural logarithm of this value was taken to reduce skew.
A value greater than 0 means more than 50% concordance in the data, a value less than zero means less than 50% concordance in the data.

Post GERD Symptom Severity
Periodo de tiempo: 2 weeks (baseline and 2 week follow-up)
|
GERD symptom severity at follow-up was assessed by self-report on a 7-day symptom diary (symptoms collected days 8-14 after the study visit).
Possible daily scores ranged from 0-12 with higher scores indicating more severe symptoms (sum of daytime heartburn, nighttime heartburn, and acid regurgitation symptoms each rated 0-4 in severity [none, mild, moderate, severe, very severe]).
Daily scores across the 7 days were averaged to create the Post GERD symptom severity score.

Percent Change in Patient's GERD Symptoms
Periodo de tiempo: 2 weeks (baseline and 2 week follow-up)
|
Percent change in patient's GERD symptoms was calculated as: (post GERD symptom severity - baseline GERD symptom severity) / baseline GERD symptom severity*100. GERD symptom severity scores were averaged across 7 day baseline and follow-up periods from a symptom diary (adapted from Miner P, 2002; PMID 12094846). Scores ranged from 0-12 with higher scores indicating more severe symptoms (sum of daytime heartburn, nighttime heartburn, and acid regurgitation each rated 0-4 in severity [none, mild, moderate, severe, very severe]). |
