Area of Science:

  • Gastroenterology
  • Medical Devices
  • Digital Health

Background:

  • Functional defecatory disorders (FDDs) are prevalent globally, impacting quality of life.
  • Traditional biofeedback therapy for FDDs is resource-intensive and limited to clinical settings.
  • A novel wireless, smartphone-based biofeedback device has been developed to increase accessibility.

Purpose of the Study:

  • To pilot test a new wireless, smartphone-based biofeedback device for treating FDDs.
  • To assess the feasibility and preliminary efficacy of the device in a clinical setting.
  • To gather data supporting future home-based, randomized controlled trials.

Main Methods:

  • A pilot study involving patients with FDDs from March to July 2018.
  • Daily 30-minute biofeedback sessions using the smartphone device for two weeks.
  • Assessment of bowel satisfaction (VAS), constipation symptoms (PAC-SYM), quality of life (PAC-QOL), and balloon expulsion time.

Main Results:

  • Ten participants completed the study, with significant improvements observed.
  • Increased spontaneous and complete spontaneous bowel movements, and Visual Analogue Scale (VAS) scores.
  • Reduced Patient Assessment of Constipation-Symptoms (PAC-SYM) and Quality of Life (PAC-QOL) scores, and shorter balloon expulsion times.

Conclusions:

  • The wireless, smartphone-based biofeedback device is feasible for clinical use in treating FDDs.
  • The device shows promise in improving constipation and related symptoms.
  • Results support the development of a home-based, randomized controlled trial for this technology.
