What is gravitational insecurity?
Gravitational insecurity(GI) refers to an excessive fear of ordinary movement, being out of
an upright position, or having one’s feet off the ground. Children with this fear are
uncomfortable with gravity, and their reactions are out of proportion to any real danger
that exists or to any postural deficits the child may have. A child that struggles with
gravitational insecurity is fearful and anxious about normal movement. They are
uncomfortable in a position that is not upright and anxiety sets in when their feet are off the
ground. There is usually an irrational fear of heights that accompanies their movement
around the house and within their environment.
Gravitational insecurity in a child will manifest itself in the following ways:
Fear of heights
Overwhelmed when head position changes, especially when inverted (upside down)
Avoidance of stairs
Dislikes high playground equipment
Fear of falling
Anxious when feet leave ground
Poor visual discrimination in the environment
Seems unbalanced in walking at times
What causes gravitational insecurity?
Gravitational insecurity is a form of over-responsiveness to vestibular sensations detected
by the otolith organs. Otolith organs (located in the inner ear) detect linear movement
through space and the pull of gravity. Gravitational insecurity is associated with poor
otolithic vestibular processing.
How do we know if the child has gravitational insecurity?
Children with gravitational insecurity may display a fear of heights or be overwhelmed by
changes in head position. Often they exhibit unwarranted fear, anxiety, or avoidance of
stairs, elevators, high playground equipment, or uneven surfaces. These children tend to
move slowly and carefully and may refuse to participate in gross motor activities.
How can we help child to overcome gravitational insecurity?
Sensory integration therapy is commonly used to treat gravitational insecurity. By providing
your child with graded vestibular information, he can learn to process information more
effectively. Sensory experiences are introduced slowly and gradually so your child does not
perceive these experiences negatively.
