FASED: Footstool in Alleviating Symptoms of Evacuation Disorder

The purpose of this research study is to compare the use of footstools of 2 different heights in patients with symptoms of pelvic floor dysfunction such as straining excessively during bowel movements and a sense of incomplete emptying. We are testing these footstools to see if using a footstool can improve these symptoms. Participants who enroll will be randomly assigned to either a 7 or 9 inch footstool. They will use the footstool for 8 weeks. During this time they will complete some online surveys about their bowel symptoms.

Study Overview

Detailed Description

Pelvic floor dysfunction is a very common problem. The prevalence of this problem is estimated to be about 16 per 100,000 person years. In one study, 52% of patients with delayed gastric emptying and symptoms of nausea and vomiting had an evacuation disorder. In this condition, there is either impaired relaxation of the pelvic floor muscles or weakness of the pelvic floor muscles. This combined usually with impaired ability to sense presence of and quantity of stool and gas in the rectum leads to difficulty evacuating stool and gas. Characteristically, these patients have difficulty emptying stool even when its soft and pasty. Some of them can only feel empty when their stools are watery. However, diarrhea comes with its inherent risks of accidental bowel leakage.

The management of pelvic floor disorders is primarily pelvic floor biofeedback therapy. The purpose is to correct the abnormal physiology to help improve emptying. Additional therapies include use of stimulant suppositories and enemas and use of foot stool. The premise behind use of a foot stool is that is helps relax the pelvic floor muscle. While there are several companies making footstools, there is surprisingly very sparse literature supporting their use.

The purpose of this research study is to investigate whether using a footstool could improve bowel symptoms in patients who experience symptoms of pelvic floor dysfunction. Participants who are eligible and enroll will complete a 2 week baseline bowel diary followed by an 8 week period during which they will be asked to use a footstool provided to them. They will be randomly assigned either to a 7 or a 9 inch footstool. During this period they will also complete surveys about their bowel symptoms.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: 7 Inch footstool
Participants in this group receive a 7 inch footstool
Use of a toilet footstool during defecation for 8 weeks. Participants in this group received a 7-inch footstool designed to elevate the feet and modify toileting posture to facilitate bowel evacuation. The intervention was performed during routine bowel movements at home.
Other Names:
  • 7 inch
Active Comparator: 9 inch footstool
Participants in this group receive a 9 inch footstool
Use of a toilet footstool during defecation for 8 weeks. Participants in this arm received a 9-inch footstool designed to elevate the feet and modify toileting posture to facilitate bowel evacuation. The intervention was performed during routine bowel movements at home.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Average Weekly Complete Spontaneous Bowel Movements (CSBMs)
Time Frame: 8 weeks
The change in average weekly number of complete spontaneous bowel movements (CSBMs) from baseline to Week 8 will be compared between participants randomized to the 7-inch footstool and participants randomized to the 9-inch footstool. A CSBM is defined as a spontaneous bowel movement associated with a self-reported sense of complete bowel evacuation, as recorded in the daily bowel diary. Baseline values will be calculated from the 2-week pre-intervention period.
8 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Irritable Bowel Syndrome Symptom Severity Score
Time Frame: 8 weeks
Change in symptom severity from baseline to Week 8 as measured by the Irritable Bowel Syndrome Severity Scoring System (IBS-SSS). The IBS-SSS is a patient-reported outcome measure ranging from 0 to 500 points, with higher scores indicating more severe IBS symptoms (worse outcome) and lower scores indicating improvement in symptom severity.
