Clinical Trial Summary

This study will be conduct to determine the effect of bilateral transcutaneous tibial nerve stimulation on treating postpartum constipation

Description:

TTNS was effective in treating constipation .It was believed that re-establishment of normal colonic function may be possible with neuromodulation of sacral nerve stimulation (SNS) that may improve constipation symptoms but it is expensive and invasive . Percutaneous tibial nerve stimulation (PTNS) is an alternative method of neuromodulation that has shown efficacy in constipation and it stimulates L4-S3 nerve roots of sacral plexus that supply the pelvic floor and lower gastrointestinal tract, Transcutaneous tibial nerve stimulation (TTNS) targets the tibial nerve in a similar fashion to PTNS but it is cheaper and does not require needle puncture .There were few studies showed that TTNS has been used and shown to be effective for treating constipation, but till now, there is no previous study illustrating it's effect specifically on postpartum constipation. So, this study will be the first one in this issue.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Bristol Stool Form Scale (BSFS)	It is a formal research tool used to assess stool consistency and intestinal transit rate. It is an ordinal scale used to rate and categorize stool into seven classifications, according to stool consistency It is also useful in evaluating the effectiveness of an intervention for gastrointestinal tract disease and clinical assessment. It helps people to report on stool consistency adequately, thus proving a guide in the diagnosis and treatment of gastrointestinal disorders.It classifies stool into seven categories ranging from hard lumps like nuts stool (type 1) to watery without solid pieces, entirely liquid (type 7). Types 1 and 2 are indicative of constipation, types 3 and 4 are considered normal stool consistency that is easy to defecate, while types 6 and 7 are considered abnormal consistency .	up to 4 weeks
Primary	Patient Assessment of Constipation -Symptom Questionnaire (PAC-SYM)	It is frequently used in clinical trials of constipation, it has emerged as an important tool for assessing the severity of patient-reported symptoms of constipation. It consists of 12-item questionnaire that divided into three symptom subscales: abdominal (four items); rectal (three items); and stool (five items). Items are scored on 5-point Likert scales, with scores ranging from 0 to 4 (0 = 'symptom absent', 1 = 'mild', 2 = 'moderate', 3 = 'severe' and 4 = 'very severe'). A mean total score in the range of 0-4 is generated by dividing the total score by the number of questions completed; the lower the total score, the lower the symptom burden. Observational data have shown that PAC-SYM questionnaire has internal consistency, test-retest reliability and concurrent validity, and to be responsive to change over time .	up to 4 weeks
Primary	Patient Assessment of constipation quality of life questionnaire (PAC-QOL)	The validated PAC-QOL questionnaire consists of 28 items grouped into 4 subscales ; physical discomfort , psychosocial discomfort, in addition to worries and concerns, and satisfaction, investigating the effects of constipation on the patient's quality of life in the recent 2 weeks. The first three subscale comprise the patient dissatisfaction index (where higher great corresponding to worse quality of life) the satisfaction subscale include 4 items, (where higher great corresponding to improve quality of life .	up to 4 weeks
Primary	Rome III criteria: Rome III criteria: Rome III criteria	It will be used to confirm the diagnosis of constipation for all participating women in both groups A and B to ensure that they will meet the eligibility criteria . All women should have at least two of the following criteria: Fewer than three spontaneous bowel movements per week. Straining during at least 25% of defecation attempts. Lumpy or hard stools for at least 25% of defecation attempts. Sensation of anorectal obstruction or blockage for at least 25% of defecation attempts.; Sensation of incomplete defecation for at least 25% of defecation attempts. Manual maneuvering required to defecate for at least 25% of defecation attempts (e.g., digital evacuation, support of the pelvic floor).; Loose stools are rarely present without the use of laxatives.	up to 4 weeks
