Hyperactivated motility of CD1 sperm increased during capacitation reaching maximal levels of ∼20 30% by 90 min, and the percentage of nonvigorous motility patterns (slow and weakly motile) also increased during this 2-hr interval.
Spermatozoa which represent various motility patterns including immotile sperm, slightly motile sperm, twitching sperm, slow moving sperm, highly motile sperm were scored.

Lu WY, Bieger D. Vagovagal reflex motility patterns of the rat esophagus.
The importance of pacemaker systems in mammals has been demonstrated by functional alterations, which change gut motility patterns, leading to pathological conditions and sometimes death.
When M. xanthus is starved for nutrients, complex motility patterns are initiated to convert a fiat two-dimensional swarm to a spherical fruiting body.
Changes in motility patterns, toward a more circular motility during cooling and PT, could be noticed where individual spermatozoa showed a capacitation-like motility pattern.
We quantified changes in their swimming activity and in the kinematics and geometrical properties of their motion, three important descriptors of the motility patterns of zooplankters.
This work demonstrates that control of RhoA can program the motility patterns of living cells and has implications in studying the relationship between cell morphology and motility.
Nutrients are absorbed across a continuous epithelium that lines the intestine, and contents are moved along the length of the intestine by stereotypical motility patterns.
After preparation of semen samples, changes in motility patterns were studied by CASA, calcium uptake by spectrofluorimetry, and ROS generation, spontaneous acrosome reaction, and lipid disorder by means of flow cytometry.
