Constipation is a common gastrointestinal disorder that impairs quality of life. Evaluating bowel motility via traditional methods, such as MRI and radiography, is expensive and inconvenient. Bowel sound (BS) analysis has been proposed as an alternative, with BS-time-domain acoustic features (BSTDAFs) being effective for evaluating bowel motility via several food and drink consumption tests. However, the effect of BSTDAFs before drink consumption on those after drink consumption is yet to be investigated. This study used BS-based stimulus-response plots (BSSRPs) to investigate this effect on 20 participants who underwent drinking tests. A strong negative correlation was observed between the number of BSs per minute before carbonated water consumption and the ratio of that before and after carbonated water consumption. However, a similar trend was not observed when the participants drank cold water. These findings suggest that when carbonated water is drunk, bowel motility before ingestion affects motor response to ingestion. This study provides a non-invasive BS-based approach for evaluating motor response to food and drink, offering a new research window for investigators in this field.
便秘是一种常见的胃肠道疾病，会降低生活质量。传统的评估肠道动力的方法如 MRI 和射线照相术既昂贵又不方便。肠音（BS）分析已被提议作为一种替代方法，通过几项食物和饮料消耗测试，BS 的时域声学特征（BSTDAFs）可有效评估肠道动力。然而，在饮用饮料之前的 BSTDAFs 对饮用饮料之后的影响尚未得到研究。本研究使用基于 BS 的刺激-反应图（BSSRPs）在 20 名接受饮用测试的参与者中对此进行了研究。在饮用碳酸水之前每分钟 BS 的数量与碳酸水前后的比例之间存在强烈的负相关。然而，当参与者饮用冷水时，并没有观察到类似的趋势。这些发现表明，当饮用碳酸水时，摄入前的肠道动力会影响对摄入的运动反应。本研究提供了一种基于 BS 的非侵入性方法来评估对食物和饮料的运动反应，为该领域的研究人员提供了一个新的研究窗口。
