In biology, motility is the ability of organisms and fluid to move or get around. A microbiologist might test and compare the motility of various single-celled organisms. An easy way to remember that motility means the ability to move without help is the mot- at the root of the word. It's the same root that's found in motor, which is, of course, the engine that drives a car. If you've got good motility then your motor is working.
Motility Testing. In the Motility Center at Nationwide Childrenâs Hospital, we diagnose complex motility disorders using advanced expertise and technology. Motility testing techniques study how the intestine moves, contracts and relaxes. It can also measure intestinal perception, including the threshold for discomfort and pain from the intestine.
