Colon cleaning is essential for the safe and accurate inspection of mucosa and early diagnosis of lesions, but course of preparation is one of the most difficult aspects of colonoscopy. This study was conducted to compare the degree of colon preparations between walking and non walking groups in patients who referred to the colonoscopy department of Razi hospital.

This one-blind randomized clinical trial was conducted on eligible individuals who had colonoscopy procedures. The patient randomly allocated into two groups of intervention (walking) and non intervention (without walking). After completion of the colonoscopy, data were collected with a specific questionnaire, then the number of steps and distance traveled was registered using the smart wristband of the Xiaomi model of the Mi Band 2 model. Intestinal cleansing was determined using the Boston criteria. The clinical trial code for this study is ISRCTN32724024.

In this study, 262 patients were studied in two groups of intervention (walking) and non intervention (without walking). There was no meaningful relationship between walking and better bowel cleansing in these groups. But when we divided individuals regardless of our intervention, only on the basis of walking, the difference in bowel preparedness was significant in the two groups so that in the group of more than 6900 steps, intestinal clearing was better than the group under 6900 (P<0.005). There was no relationship between sex, walking, body mass index, diarrhea, constipation, history of gastrointestinal surgery and history of gynecological surgery with intestinal cleansing. But there was a relationship between age, smoking and history of chronic diseases with intestinal cleansing (P<0.005).

It seems that conducting such researches with greater volume and even different exercises would help to improve the conventional methods of bowel preparation for colonoscopy.
