Time to Visual Analogue Scale 7 (VAS7) During Thermal Stimulation at 1.5 Hours Post-Dose.
A probe (bag) was inserted 7cm above the lower esophageal sphincter (LES). Heat stimuli were applied by recirculation of heated water in the bag. Prior to recirculation the bag is filled with 7mL to ensure adequate mucosal contact. Water was heated up to a maximum of 63° C and the stimulation was continued until VAS 7 was reached. The intensities of the non-painful sensations were scored with the following descriptors added to facilitate the scoring: 1. = vague perception of mild sensation 2. = definite perception of mild sensation 3. = vague perception of moderate sensation 4. = definite perception of moderate sensation For painful sensations the patients will use the scale from 5-10 anchored at: 5. = pain detection 6. = slight pain 7. = moderate pain 8. = medium pain intensity 9. = intense pain 10. = unbearable pain
Time frame: 1.5 hours post dose

Time to Visual Analogue Scale 7 (VAS7) During Thermal Stimulation at 2.5 Hours Post Dose
A probe (bag) was inserted 7cm above the lower esophageal sphincter (LES). Heat stimuli were applied by recirculation of heated water in the bag.

Volume at Visual Analogue Scale 7 (VAS7) During Mechanical Stimulation at 0.5 Hours Post Dose
A probe (bag) was inserted 7cm above the lower esophageal sphincter (LES). Volume change in the bag was recorded continuously at each level of the visual analogue scale (VAS) and up to VAS7 (Volume at Visual Analogue Scale 7). The intensities of the non-painful sensations were scored with the following descriptors added to facilitate the scoring: 1. = vague perception of mild sensation 2. = definite perception of mild sensation 3. = vague perception of moderate sensation 4. = definite perception of moderate sensation For painful sensations the patients will use the scale from 5-10 anchored at: 5. = pain detection 6. = slight pain 7. = moderate pain 8. = medium pain intensity 9. = intense pain 10. = unbearable pain

Current at Visual Analogue Scale 7 (VAS7) During Electrical Stimulation 0.5 Hours Post Dose
A probe (bag) was inserted 7cm above the lower esophageal sphincter (LES) and stimulations were performed at approximately 8 cm above the LES. The intensity of the stimuli is increased steadily in steps of 0.5 to 1 mA and the intensity corresponding to the VAS levels 1, 3, 5 and 7 were recorded. The current will be increased until the patient report moderate pain (VAS 7) or max 80 mA. The intensities of the non-painful sensations were scored with the following descriptors added to facilitate the scoring: 1. = vague perception of mild sensation 2. = definite perception of mild sensation 3. = vague perception of moderate sensation 4. = definite perception of moderate sensation For painful sensations the patients will use the scale from 5-10 anchored at: 5. = pain detection 6. = slight pain 7. = moderate pain 8. = medium pain intensity 9. = intense pain 10. = unbearable pain
