The C.A.M. Report
Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Biofeedback: Constipation and fecal incontinence

     Researchers from the University Hospital, in Tübingen, Germany, reviewed the evidence.

    First, the details.

    • For constipation, 8 studies were identified.
    • For fecal incontinence, 11 trials were identified.
    • The data were pooled and a meta-analysis conducted.

    And, the results.

    • Biofeedback training was significantly better than non-biofeedback (laxatives, placebo, sham training, and botox injection).
    • Biofeedback was as effective as electromyographic biofeedback.

    Fecal incontinence

    • Biofeedback was as effective as non-biofeedback therapy.
    • There were no differences among various modes of biofeedback.

    The bottom line?
    The authors commented that the studies were flawed, with variable endpoints and a lack of quality.

    Despite this, they concluded, “Biofeedback training for pelvic floor dyssynergia [aka anismus: failure of pelvic floor muscles to relax, or a paradoxical contraction of these muscles, with defecation] shows substantial specific therapeutic effect.”

    By comparison, “Biofeedback training for incontinence is still lacking evidence for efficacy.”

    “In both conditions, biofeedback seems to play a minor role.”

    More positive reports on biofeedback and fecal incontinence are here and here.
