Bilateral coordination is the ability to use both sides of the body together in a coordinated way. It is also known as bilateral integration. Many childhood and school activities require your child to be able to use both hands together well.
A child who is delayed in developing bilateral coordination skills may prefer to use one hand alone rather than both hands together, and may appear awkward or clumsy in some gross and fine motor activities.
Studies have also found that there is a link between bilateral motor skills and academic performance. Some researchers suggest that coordination exercises may stimulate the parts of the brain that are needed for thinking and for paying attention.
Coordinated bilateral movements engage different sensory and motor areas on both hemispheres of the brain as well as the corpus callosum and cerebellum. Those parts of the brain work together to help to produce the complex bilateral movements that make up so much of our daily lives.
Below are just a few of the many activities that need both sides of the body to work together well. When bilateral integration is poor, then the child may avoid these activities, or the child may seem clumsy, inefficient and uncoordinated when taking part in them.
Your child needs to develop bilateral coordination skills in three different areas: symmetrical movements, reciprocal movements, and movements requiring a supporting hand.
Symmetrical bilateral movements are usually the first ones to be mastered, followed by reciprocal movements and lastly the asymmetrical movements of a leading and supporting hand. However, your child does not need to completely master one kind of movement before moving on to the next - there is a lot of overlap and interdependence in the development of coordination skills.
Here is a brief breakdown of each kind of bilateral movement:
Symmetrical movements have each leg or hand doing the same action at the same time, for example rolling out pastry with a rolling pin, pushing a wheelbarrow, or clapping hands.
It is important that both sides of the body do the same movement at the same time, with an equal amount of force.
Watch out for: your child using one hand to do something that needs two hands, or having one hand doing more of the work, resulting in a lop-sided movement. In gross motor activities, watch out for one leg doing a better job or jumping/skipping etc than the other.
Reciprocal movements are actions where first one hand or leg and then the other carries out the same movement in a rhythmical way.
Examples would be pulling a rope hand-over-hand or pedaling a bike.
Reciprocal movements are also called alternating movements.
Look out for: movements which are jerky and don't flow well, or when one hand or leg does more work than the other, resulting in lop-sided action.
We often use one hand to play a supporting role while the other hand does more skilled work, such as cutting with scissors, threading beads or drawing a line with a ruler.
Both hands are equally important, but one is specialising in tool use, and the other is specialising in assisting. Both hands need to work together smoothly in a coordinated way to ensure the task is completed well!
During handwriting, if a child does not stabilise the paper with the non-writing hand, then writing can be less efficient.
Watch out for: awkward positioning, where the supporting hand does not help the leading hand properly. During scissor cutting activities, check that the supporting hand is holding and moving the paper in such a way that the cutting hand can easily keep the scissors on the line. In some cases, the child may avoid using the supporting hand altogether!
If you are at all concerned about your child's development, please consult your health professional. The information on this page is not intended to take the place of an occupational therapy evaluation and treatment!
The vestibular system (which is situated in the inner ear and helps the brain to process movement information) plays a vital role in a child's physical development.
Children who struggle to process movement information from their vestibular systems may also struggle with bilateral integration.
For this reason, occupational therapists who use sensory integration techniques may include specific movement activities in their therapy sessions to stimulate the vestibular system before carrying out activities to boost bilateral coordination skills.
At home, you can give your child's vestibular system a boost by having your child jump on a trampoline, roll on the grass, use a swing or do somersaults.
Now that you know what the different kinds of bilateral movements are, you can look out for ways of incorporating these into your child's daily routine.
Check out a few outdoor and indoor activities that I have photographed with instructions.
Although symmetrical movements are often easier, your child does not have to master these before moving on to alternating movements – you can combine different kinds of movements through different activities.
If the free activities on my site are not enough, you may want to access the 24 pages of photographed activities in my downloadable e-book!
Lots of variety and really practical ideas to make it easy for parents to work on these skills.
All for the price of a couple of coffees!
