Biofeedback therapy shows moderate to high success rates for ano-rectal incontinence and chronic constipation. However, its effectiveness is limited in neurogenic incontinence and requires further investigation for patient selection in cases of outlet obstruction.

Area of Science:

  • Gastroenterology
  • Pelvic Floor Rehabilitation
  • Neurology

Context:

  • Biofeedback therapy is a treatment for functional defecation disorders.
  • Ano-rectal incontinence and chronic constipation are common conditions.
  • Neurogenic incontinence presents unique challenges for treatment.

Purpose:

  • To evaluate the efficacy of biofeedback in treating ano-rectal incontinence and chronic constipation.
  • To identify patient subgroups who may benefit from biofeedback therapy, particularly in cases of outlet obstruction.
  • To highlight the limitations of biofeedback in neurogenic incontinence.

Summary:

  • Biofeedback demonstrates success rates of 50-92% for ano-rectal incontinence and 35-90% for chronic constipation.
  • In neurogenic incontinence, biofeedback yields poor results.

  • For outlet obstruction, biofeedback is effective only when paradoxical contractions (anismus) are present during straining.

    • Impact:

    • Further research is needed to refine patient selection criteria for biofeedback therapy.
    • Optimizing biofeedback treatment can improve outcomes for functional defecation disorders.
    • Understanding the specific mechanisms of biofeedback failure in certain conditions is crucial for advancing treatment strategies.
