Insights

Adding biofeedback therapy to transcutaneous functional electrical stimulation (TFES) improved fecal incontinence (FI) in children. Both TFES alone and TFES with biofeedback showed significant symptom reduction and improved quality of life.

Area of Science:

  • Pediatric Gastroenterology
  • Urology
  • Rehabilitation Medicine

Background:

  • Functional non-retentive fecal incontinence (FNRFI) affects children's quality of life.
  • Conventional treatments may not be effective for all FNRFI cases.

Purpose of the Study:

  • To compare the efficacy of transcutaneous functional electrical stimulation (TFES) combined with biofeedback therapy versus TFES alone in treating pediatric FNRFI.
  • To evaluate the impact of these treatments on fecal incontinence scores, pain, bowel habits, and quality of life.

Main Methods:

  • A prospective, single-center randomized clinical trial involving 40 children with FNRFI.
  • Patients were randomized into two groups: TFES + biofeedback (Group A) and TFES alone (Group B).
  • Assessments included pediatric fecal incontinence scores, pain scores, bowel habit diaries, and quality-of-life questionnaires before, during, and after treatment (6-month follow-up).

Main Results:

  • Fecal incontinence significantly improved in 65% of patients receiving TFES + biofeedback and 55% receiving TFES alone.
  • Both groups showed significant reductions in fecal incontinence scores, maintained at 6 months.
  • Significant improvements in quality of life were observed in both groups at 6 months, with no significant difference between them.

Conclusions:

  • Transcutaneous functional electrical stimulation (TFES) combined with biofeedback therapy is an effective treatment for pediatric functional non-retentive fecal incontinence.
  • TFES alone also demonstrates significant benefits for FNRFI symptoms and quality of life.
  • Combining electrical stimulation with other therapies can improve outcomes for FNRFI patients refractory to conventional treatments.
