Brief Summary

Constipation is a common problem in the general population. Defecation disorders caused by abnormal contraction or insufficient relaxation of the pelvic floor muscles during defecation may be one of the most possible causes of constipation. Although constipation is not life-threatening, it may have a significant impact on the quality of life. Aerobic exercise has been shown to improve symptoms of constipation in adults with constipation. However, there is no research investigating the effects of a multimodal exercise training on pelvic floor symptoms and pelvic floor muscle function in this population and only few studies have evaluated the pelvic floor muscle function using objective assessment tools among this population. The aim of the study is to investigate the effect of a multimodal exercise training program on constipation symptoms and pelvic floor muscle function in adults with constipation. The investigator will conduct a randomized controlled trial to evaluate the effectiveness of exercise training for adults with constipation. This study hypothesizes that (1) a multimodal exercise training can improve pelvic floor symptoms and function in adults with constipation, and (2) the improvement in exercise training group will be higher than that in control group.

Outcome Measures

Primary Outcomes (4)

  • Severity of Constipation Symptoms

    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.

    absolute values at 8 weeks

  • Constipation Symptoms

    A Seven Day Bowel Diary includes items regarding the stool frequency, presence of incontinence, excessive straining, manual maneuver, or pain during defecation, and the use of laxatives.

    absolute values at 8 weeks

  • Constipation Symptom-Stool Consistency

    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.

    absolute values at 8 weeks

  • Constipation Symptom-Time Spent During Defecation

    A Seven Day Bowel Diary includes items regarding time spent during defecation.

    absolute values at 8 weeks

Secondary Outcomes (7)

  • The Pelvic Floor Muscle Coordination Measured by the Pelvic Floor Muscle Coordination Scale

    absolute values at 8 weeks

  • The Pelvic Floor Muscle Strength Will be Measured by Digital Rectal Examination.

    absolute values at 8 weeks

  • The Pelvic Floor Muscle Function Will be Measured Using Anorectal Manometry.

    absolute values at 8 weeks

  • The Pelvic Floor Muscle Endurance Will be Measured Using Anorectal Manometry and Stopwatch.

Study Arms (2)

Exercise training group

EXPERIMENTAL

* Aerobic exercise * Resistance exercise (including pelvic floor muscle training with biofeedback) * Stretching exercise * Home exercise

Other: multimodal exercise training

Control group

NO INTERVENTION

・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.

Interventions

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.
