[Biofeedback effectiveness in patients with fecal incontinence]

Area of Science:

• Pelvic floor rehabilitation
• Gastroenterology
• Physical therapy

Background:

• Fecal incontinence (FI) is the involuntary loss of bowel control.
• Biofeedback therapy is a recognized effective treatment for FI.
• Optimizing biofeedback therapy requires understanding the number of sessions needed for maximum benefit.

Purpose of the Study:

• To determine the optimal number of weekly electromyographyc biofeedback therapy sessions.
• To identify when maximum sphincteric complex contraction is achieved in patients with FI.

Main Methods:

• A retrospective, descriptive, and longitudinal study design.
• 65 patients diagnosed with fecal incontinence were enrolled.
• Weekly electromyographyc biofeedback sessions (up to 6) were administered, measuring sphincteric complex contraction; analyzed using a two-way Friedman test.

Main Results:

• Pelvic floor contraction values significantly increased by the third biofeedback session.
• No statistically significant improvements in contraction were observed in sessions beyond the third.
• The study evaluated 65 patients with fecal incontinence.

Conclusions:

• Maximum sphincteric complex contraction is consistently reached by the third weekly biofeedback session.
• Subsequent biofeedback sessions do not yield further significant gains in muscle contraction.
• This finding suggests a potential endpoint for biofeedback therapy in FI management.
