Clinical Trial Summary

This study is designed to validate a new direct method for the measurement of stool consistency, using Texture Analyser. Forty healthy subjects are enrolled in this trial for collection of stool samples. Every stool produced during 2 collection periods of approximately 60 hours each is collected and subjected to the measurement of consistency using Texture Analyser. The stool consistency results are compared with the Bristol Stool Form Scale scores for each stool. The relationships of stool consistency with other stool parameters, bowel habit and sleeping habit are also evaluated.

Clinical Trial Description

It is now obvious that the proper functioning of the gastrointestinal tract has a positive effect on the quality of life. Normal bowel habits vary considerably from person to person with regard to frequency of bowel movements, and bulk and consistency of stools. Constipation is the common digestive complaint in European populations, and softening stool consistency can be regarded as beneficial for such population in terms of reducing incidence of hard or lumpy stools .

The Bristol Stool Form Scale (BS) is validated as a surrogate measure for gastrointestinal transit time, and has been also applied to an evaluation of stool consistency. Subjects compare their stool with the BS chart consisting of seven categories and choose one score which has a nearest analog form. The BS has been widely used in the studies to evaluate changes in stool consistency after dietary intervention using probiotics and/or prebiotics. However, there is a lack of evidence in the validity of BS to yield consistent and reproducible estimates of changes in stool consistency over time. In order to obtain a closer estimate of its change, it would be preferred to use a more directly observable and objective parameter or combination of parameters.

From the above mentioned backgrounds, this study is conducted to validate a new direct method for the measurement of stool consistency, using Texture Analyser: TA.XTExpress Texture Analyser (Stable Micro Systems Ltd.). ;
