Gravitational Insecurity
2009-08-19 adminThe ear is usually associated with hearing. It may seem odd, but parts of the ear contribute to our sense of balance and our position in space.
Structures inside the inner ear monitor head movement and are called the vestibular system. The vestibular system sends messages to the brain about the head’s position and direction of movement. As Wikipedia states: “The vestibular system sends signals primarily to the neural structures that control our eye movements, and to the muscles that keep us upright.” The signals to the part of the brain controlling eye movements are necessary so that we can do such things as catch a ball while running or even the simple act of reading.
The inner ear is not alone in the process that keeps our bodies balanced. According to the Vestibular Disorders Association our “ability to maintain balance depends on information that the brain receives from three different sources: the eyes, the muscles and joints, and the vestibular organs in the inner ears. All three of these sources send information in the form of nerve impulses from sensory receptors, special nerve endings, to your brain.”
As you might guess, this is a very complex system that processes information in microseconds. And like all things human, sometimes things can go wrong.
One of the many problems that can occur is called “gravitational insecurity.” Sensorysystemsclinic.com defines this insecurity as “an irrational fear of movement. Children with gravitational insecurity may exhibit limited participation in gross motor play; avoidance or fear of escalators, elevators, or cars; or resistance to being off the ground.”
We might argue that it is not irrational. Persons with this disorder are acting logically. It is rational to become acutely afraid if you believe you are going to fall and land on the back of your head. The difficulty is that the judgement about falling is based on incorrect information. Either the signals sent to the brain are false or the way in which the brain processes those signals is flawed; or both.
Perhaps it would be better just to say that people with gravitational insecurity display fears of movement that to us appear irrational and misplaced.
Autismsa.org.au has a nice information sheet about gravitational insecurity. Symptoms of this problem may include:
- “anxiety when feet leave the ground
- fear of falling or being moved suddenly
- dislike being upside down
- uneasiness when walking on uneven surfaces
- intolerance of movement, sometimes manifested by nausea, vomiting and flushing
- upset when tipped backward e.g. for nappy change, lying down to sleep.”
Some of their recommendations in treating this problem include:
“Encourage movement activities as part of a daily routine. Movement activities can include:
swings, hammock, scooter board, slide, see saw, bikes, barrel, rolling down a slope, rolling up
in a rug, climbing play equipment, trampoline, rocking horse, rocking chair, sit and spin toys
etc.”
They have further suggestions to help a child or older person with this problem on their site and we encourage you to read the article.
