Brief summary

When conservative treatment fails for constipation or faecal incontinence, biofeedback and pelvic floor health therapy are two different management options. These two modalities are often thought to be similar by some physicians due to both employing components of pelvic exercise. However, these two modalities have very distinct programmes and are usually delivered by different health care professionals (nurses versus physiotherapists). Despite this, no randomised controlled trial has been performed to date to compare them for both indications. This study aims to investigate any difference in outcome between the two modalities.

Interventions

Pelvic floor health therapy: Patients in this arm will undergo total of six one-to-one sessions occurring every 1-2 weeks (6-12 weeks). - each session will be guided by a physiotherapist and up to 60 minutes long. -Patients will be prescribed individualised exercises based on each patient’s presenting condition, pattern of their symptoms and clinical assessment of pelvic floor function. -Patients will be guided through a series of pelvic floor exercises during the session and will also be gi

Pelvic floor health therapy: Patients in this arm will undergo total of six one-to-one sessions occurring every 1-2 weeks (6-12 weeks). - each session will be guided by a physiotherapist and up to 60 minutes long. -Patients will be prescribed individualised exercises based on each patient’s presenting condition, pattern of their symptoms and clinical assessment of pelvic floor function. -Patients will be guided through a series of pelvic floor exercises during the session and will also be given at-home exercises. -Some examples include contraction and relaxation of pelvic floor muscles in different positions and abdomen strengthening exercises. At home exercise will be similar but at much shorter duration. Home exercises may be prescribed daily or multiple times a day. -For sessions with physiotherapists, exercises may be assisted by an anal pressure probe or electrical stimulation if it is deemed helpful by the treating physiotherapist. Attendance and progress will be recorded on clinical research database.
