Transcutaneous Electrical Acupoint Stimulation (TEAS) for Chronic Constipation

Description

Transcutaneous electrical acupoint stimulation (TEAS) is an emerging technology for non-invasive neuromodulation that has broad potential implications and warrants further study. The investigators' clinical experience from the University of California, Los Angeles (UCLA) Center for East-West Medicine (CEWM) has also demonstrated that TEAS can be used as an effective self-care tool for patients with chronic illness who do not have the time or resources for frequent acupuncture treatments. Chronic constipation is the chosen area of study because of the large population with a substantial impairment in health-related quality of life and work productivity. The investigators have recently completed a randomized controlled trial (RCT) demonstrating the benefit of perineal self-acupressure on quality of life measurements in this population, which supports investigation into other acupuncture-based self-care interventions. Given these findings, the investigators hypothesize that home patient-administered TEAS can provide measurable improvements in both symptom severity and health related quality of life.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
