NCT04953728

Brief Summary

This study aims to determine the most effective treatment with Transcutaneous Electrical Acustimulation (TEA) for Irritable Bowel Syndrome with Constipation (IBS-C) by comparing efficacy between 5 separate sessions. The rectum pressure as measured by a device called a barostat will be compared between visits. Each session will be testing a different combination of frequency and body position of the electrodes. Electrodes placed at either the wrist or knee will be stimulated at either 25 Hz or 100 Hz.

Outcome Measures

Primary Outcomes (2)

  • Change in Pressure of Maximum Tolerance in mmHg of the Rectum as Measured by a Barostat Device When Compared to Pre-TEA Administration.

    The barostat device will measure the pressure changes in the rectum during controlled distension, as measured in mmHg. The study participant's maximum tolerance of distention will be compared to tolerance pre and post TEA, as well as comparing each administration to the other modalities and the sham. Higher numbers represent a higher degree of tolerance. Each participant came in for 1 treatment in 1 session on each of 5 separate days. The sequence of treatments each participant received over the course of their sessions was randomized per participant. In each session, a new baseline was established, because individuals' pain/discomfort may have changed over time between sessions. Each change value listed below represents the mean of the differences between each participant's tolerance with stimulation and that participant's baseline for that day.

    Baseline data collected up to 12 minutes; participants rested for 15 minutes; 15 minutes of treatment was administered, then rectum was distended again with treatment for up to 12 minutes. Between each of 5 sessions, participants had 1-3 weeks off.

  • Change in Pressure of Maximum Tolerance in mmHg of the Rectum as Measured by a Barostat Device When Compared to Other Modalities.

    The barostat device measured the pressure changes in the rectum during controlled distension, as measured in mmHg. The study participant's maximum tolerance of distention was compared to tolerance pre and post TEA, as well as comparing each administration to the other modalities and the sham for that person. Higher numbers represent a higher degree of tolerance. Scores were compared between modalities of body position (ST36 or PC6), frequency (100 Hz or 25 Hz), and sham. Each participant came in for 1 treatment in 1 session on each of 5 separate days. The sequence of treatments each participant received over the course of their sessions was randomized per participant. Analysis is shown as a difference in treatment-induced change between different treatment modalities rather than a comparison between the average maximums under 1 treatment or another for the group as a whole.

    After 15 minutes of treatment, rectum was distended incrementally with treatment for up to 12 minutes. Because between sessions, participants had 1-3 weeks off, the maximum time between 1 maximum-tolerated distension and another was 12 weeks.

Secondary Outcomes (4)

  • Change in Pain as Measured by Visual Analog Scale (VAS) Surveys When Compared to Pre-TEA Administration.

    Up to 8 mins between 15 and 50 mmHg during baseline. After deflating balloon, 15 mins of treatment and resumption of distention (up to 30 mins later), more surveys were taken during treatment increasing distensions up to 8 mins between 15 and 50 mmHg.

  • Change in Individual's Pain as Measured by Visual Analog Scale (VAS) Surveys at Max Distension During 1 Treatment Compared to Their Own Pain During a Different Treatment.

    Surveys taking less than 1 minute were taken at maximum-tolerated distension during treatment. Because between sessions, participants had 1-3 weeks off, the maximum time between 1 survey and another was 12 weeks.

  • Change in Maximum Volume in mL of the Rectum as Measured by a Barostat Device When Compared to Pre-TEA Administration.

    Baseline data collected up to 12 minutes; participants rested for 15 minutes; 15 minutes of treatment was administered, then rectum was distended again with treatment for up to 12 minutes. Between each of 5 sessions, participants had 1-3 weeks off.

  • Change in Pressure of First Sensation of the Rectum as Measured by a Barostat Device When Compared to Pre-TEA Administration.

    Baseline data collected up to 12 minutes; participants rested for 15 minutes; 15 minutes of treatment was administered, then rectum was distended again with treatment for up to 12 minutes. Between each of 5 sessions, participants had 1-3 weeks off.

Study Arms (1)

Subjects with IBS-C

EXPERIMENTAL

All participants will receive all treatment options. Each participant will receive all of the following treatments; 100 Hz ST36, 100 Hz PC6, 25 Hz ST36, 25 Hz PC6, as well as the sham comparator. Each administration will be performed on different dates, between 1 and 3 weeks apart.

Device: Transcutaneous Electrical Acustimulation (TEA)

Interventions

Each participant will undergo 5 sessions total at two different frequencies (25 Hz and 100Hz) with electrodes placed at two different locations (wrist and knee) and a placebo session.

Subjects with IBS-C
