Most of us don't think about the various skills we need to develop in order to complete everyday tasks. But whether we're writing, getting dressed, throwing or catching, riding a bike or even walking, we're using a skill called "bilateral coordination". Bilateral coordination is another way of saying "coordinating both sides of the body to work together". When we can coordinate our limbs individually and move them in a controlled and organized manner, all kinds of actions that could otherwise not be performed can occur. Bilateral coordination is the skill that allows us to hold a sandwich steady with one hand while cutting it with the other. It's the skill that's needed to pedal downward with one foot while pedaling upward with the other; it allows us to play instruments and tie our shoes, and it's the skill we need to throw one handed.
