Topic 4: What Is Bilateral Movement and Why Is It Important?

 

There are three types of bilateral movement:

  • Symmetrical Movement: Symmetrical movement takes place when each hand, arm or leg are doing the same thing at the same time. To be successful in symmetrical bilateral movement, both sides must be moving at the same time with the same amount of force. Examples include jumping jacks, jumping rope, and clapping.

  • Reciprocal Movement: Reciprocal or alternating bilateral movement takes place when one hand, arm or leg and then the other moves rhythmically in the same way. Reciprocal movement includes skipping, swimming, pulling a rope hand over hand, riding a bike, or marching.

  • Leading hand/Supporting hand: Leading hand/supporting hand bilateral movement is when a dominant hand is supported by the other hand. When we write, thread beads, or stir a pot, we have one hand doing the skilled work and one hand assisting. Both hands are equally important in the task but have very specific roles and must work together in a very organized and coordinated way for success.
