用不透射线标记物（形状）、放射遥测胶囊、含51 Cr的有机玻璃胶囊或游离51 Cr铬酸钠测量人类结肠的推进活动。这些技术可以很容易地检测到推进活动，其中没有一个需要使用放射性造影剂。对于含有51 Cr或游离51 Cr的胶囊，可以在同一患者中进行重复观察，而无需借助X线摄影。在使用封装的51 Cr进行测试期间，患者可以保持正常活动。如果使用低mA曝光的胶片，也可以对形状进行重复观察。结果发现，结肠腔内的压力活动显着上升期间和之后的食物，但在休息的病人，这种增加很少与推进活动。在体力活动患者推进结肠内容物显着增加餐后。当结肠推进发生时，它通过一系列的质量运动来实现。这些结果表明，在健康或疾病中，躯体活动是控制结肠运输的重要因素。
Propulsive activity of the human colon was measured with radiopaque markers (shapes), radiotelemetering capsules, Perspex capsules containing 51Cr, or with free 51Cr sodium chromate. Propulsive activity can be readily detected by these techniques, none of which requires the use of radiological contrast media. With capsules containing 51Cr or with free 51Cr repeated observations can be made in the same patient without recourse to radiography. The patient can remain normally active during the test with encapsulated 51Cr. Repeated observations may also be made with shapes, if films exposed at low mA are used. It was found that colonic intraluminal pressure activity rises markedly during and after food, but that in the resting patient this increase is rarely associated with propulsive activity. In physically active patients propulsion of colonic contents was significantly increased after meals. When colonic propulsion takes place, it does so by a series of mass movements. These results suggest that somatic activity is an important factor in the control of colonic transit in health or disease.
