Trial Outcomes & Findings for Effects of Exercise Training on Pelvic Floor Symptoms and Function in Adults With Constipation (NCT NCT04661202)

NCT ID: NCT04661202

Last Updated: 2024-08-02

Results Overview

The Patient Assessment of Constipation Symptoms questionnaire will be used to assess the severity of constipation symptoms. This questionnaire includes a total of 12 items in 3 subscales: abdominal (4 items), rectal (3 items), and stool (5 items). Participant will be asked to rank the symptoms on a five-point Likert scale, ranging from 0 (absent) to 4 (very severe). The total score ranges from 0 to 48 which will be divided by the actual number of items answered. The higher score indicates the greater severity of constipation symptoms.

Measure
Exercise Training Group
* Aerobic exercise * Resistance exercise (including pelvic floor muscle training with biofeedback) * Stretching exercise * Home exercise Multimodal exercise training: A supervised moderate-intensity exercise training session, which will include aerobic exercise with a stationary exercise bike, resistance exercise using dumbbell, theraband band, or gym ball for each major muscle groups and core muscles (including pelvic floor muscle (PFM) training with biofeedback), and stretching exercise, twice a week for 8 weeks. All exercises will be individualized based on participant's heart rate reserve and Rate of Perceived Exertion (RPE). An oximeter and a sphygmomanometer will be used to monitor the heart rate, oxygen saturation and blood pressure of the participants to ensure safety. A home exercise program will include a walking exercise for 30 minutes per day and a PFM training with the aim of completing 1\~3 sets of 8\~12 submaximal contraction of PFM by holding 6\~10 seconds with 12\~20 seconds of rest between each contraction, and it will end with 3 maximal PFM contractions by holding 1\~3 seconds 3\~6 seconds of rest between each contraction.
Control Group
.Usual care After baseline assessment, the participants will receive health and lifestyle advices related to bowel symptoms, which include maintaining moderate physical activity, healthy diet, and ideal defecation posture, and establishing a personal bowel schedule and other behavioral changes that promote regular bowel movements. Upon request, the participants will be provided with the same intervention program as the exercise training group after 8 weeks participation.

A Seven Day Bowel Diary includes the item regarding stool consistency. The Bristol Stool Form Scale describing the shapes and types of stools is used to evaluate stool consistency. This scale assigns a number (1-7) with 1 indicating hardest to 7 indicating loosest, to classify human feces based on its shape and and how formed or loose it is.

The Pelvic Floor Muscle Coordination Scale including 5 items, respiration, pelvic floor muscle contraction, extrapelvic muscle activation, pelvic floor muscle expansion, and cough will be used to evaluate pelvic floor muscle coordination. All will be evaluated by observation. The total score ranges from 0 to 10 and a higher score indicates the poorer pelvic floor muscle coordination.

Timeframe: absolute values at 8 weeks

Resting tone, maximal voluntary contraction (MVC) of external anal sphincter and puborectalis, voluntary relaxation, and three components of defecation attempts (push effort, anal relaxation, and perineal descent) will be measured. Resting pressure was scored as "0=decreased", "1=normal", or "2=increased". Maximal voluntary contraction of external anal sphincter and puborectalis were scored separately for each muscle based on the International Continence Society scale criteria as "0=absent", "1=weak", "2=moderate", "3=strong". Voluntary relaxation was assessed after MVCs and scored as "0=absent", "1=partial", or "2=complete". Push effort was scored as "0=weak", "1=normal", or "2=excessive", anal relaxation was scored as "0=impaired", "1=normal", or "2=paradoxical contraction", and perineal descent was scored as "0=absent", "1=normal", or "2=excessive".

Upon request, the participants will be provided with the same intervention program as the exercise training group after 8 weeks participation.

Timeframe: absolute values at 8 weeks

Participants will be asked to voluntarily squeeze their pelvic floor muscles by holding the contraction for 30 seconds. Anorectal squeeze pressure is measured using an anorectal manometry. The pelvic floor muscle endurance is recorded as the time (seconds) holding at \>50% of maximal voluntary contraction (squeeze pressure) in 30 seconds.

* Aerobic exercise * Resistance exercise (including pelvic floor muscle training with biofeedback) * Stretching exercise * Home exercise Multimodal exercise training: A supervised moderate-intensity exercise training session, which will include aerobic exercise with a stationary exercise bike, resistance exercise using dumbbell, theraband band, or gym ball for each major muscle groups and core muscles (including pelvic floor muscle (PFM) training with biofeedback), and stretching exercise, twice a week for 8 weeks. All exercises will be individualized based on participant's heart rate reserve and Rate of Perceived Exertion (RPE). An oximeter and a sphygmomanometer will be used to monitor the heart rate, oxygen saturation and blood pressure of the participants to ensure safety. A home exercise program will include a walking exercise for 30 minutes per day and a PFM training with the aim of completing 1\~3 sets of 8\~12 submaximal contraction of PFM by holding 6\~10 seconds with 12\~20 seconds of rest between each contraction, and it will end with 3 maximal PFM contractions by holding 1\~3 seconds 3\~6 seconds of rest between each contraction.

The International Physical Activity Questionnaire will be used to measure participants' physical activity levels. This questionnaire includes seven questions on different physical activity levels of duration and frequency and then calculated in metabolic equivalent-minutes/week. A higher score indicates a greater physical activity levels.

Patient Assessment of Constipation Quality of Life Questionnaire will be used to evaluate the quality of life in constipation patients. This questionnaire includes a total of 28 items in 4 subscales: worries and concerns (11 items), physical discomfort (4 items), psychosocial discomfort (8 items), and satisfaction (5 items). Participants will be asked to rank how constipation affects their quality of life on a five-point Likert scale, ranging from 0 to 4. A higher score indicates greater impact on quality of life.

Timeframe: absolute values at 8 weeks

Population: There were three missing data of adherence (n=3) in intervention group as the participants dropped out during the eight-week program.

Participants in intervention group will be asked to record the number of completed home exercises (pelvic floor muscle training and walking) in the exercise diary. Adherence will be calculated separately for pelvic floor muscle training and walking as the days of home exercises completed over 56 days.
