Like any other parents, we are excited when our children reach their milestones. Our son Wyatt, who has Down syndrome, is no exception. However, with his cardiac issues and his prematurity, he has some added challenges that even his peers with Trisomy 21 do not. At this time, at almost 20 months of age, he can expertly commando crawl, sit up on his own and has begun grasping the edge of things and attempting to peep over. He is not pulling himself up, standing or creeping. At times it can become frustrating and it begs the question: is there something that we can do to "speed up" this process? Right along side this comes the parental guilt: are we doing the right things for our son?
There is a lot of literature out there about treadmill walking; I will not deny that the research looks promising, especially with getting kids who are creeping (on their hands and knees) to the walking stage weeks earlier. As it turns out however, commando crawling is an extremely important stage of development that helps map and incorporate all the senses and should therefore be given as much attention as possible.
When a child learns to crawl on their stomach, they:
- learn to focus their eyes on near objects
- discover the placement of their torso, legs and arms through tactile stimulation with the floor (develop proprioception - the awareness we have of our limbs as we move them)
- Use almost all of the major muscle groups
- Learn co-ordinated movement (especially 'cross pattern movement' of right leg, left arm then left leg, right arm)
- Learn muscle balance (the ability to steady one's self using their muscles, primarily those in the 'core')
Co-ordinated movement is very important as it is a skill that we use all our lives. Developing 'cross pattern movement', that is the ability of simultaneously moving the right foot and left arm, then the left foot and right arm, is used in all forms of human movement, including walking. During belly crawling, the arms, legs and torso receive sensory (tactile) information that helps the child improve their development of such movement. Almost all the muscle groups are used and it is only by learning to alternate the flexion and extension of their joints that the child will crawl. The more the muscles are used, the stronger they become and in turn, the stronger the crawling becomes. It is in this way, the child develops their arms, legs and trunk; in conditions such as Down syndrome where there is lower muscle tone and looser ligaments, this is a very important stage.
As mentioned previously, crawling utilizes tactile and proprioceptive receptors throughout the body. The information received by these receptors during crawling comes simultaneously from both the right and left side of the body. As the child becomes more adept at crawling and integrating this sensory information, they further the development their tactile senses and in turn continue to develop their muscle tone even further. As well, they develop muscle balance, learn to use utilize vestibular balance (balance that is monitored by the sensory system in the inner ear) and continue to develop their proprioception. The more all of this is developed, the stronger the muscles and sensory connections become.
Some children with Down syndrome may take even longer than their peers to progress from a commando crawl to a creep as they may require more input and time to make the necessary connections. However, continued practice has shown to provide a strong foundation for future movement. Wyatt is one of those children. Allowing him to continue practicing his crawling and encouraging him to creep (along with his other exercises, such as weight bearing) will only strengthen his motor and sensory skills and give him the best possible practice for when he does begin to walk.
