Warning Signs Of Chiari Malformation

Poor Coordination

The part of an individual's brain that puts together the sequence of movements and then implements them is called the cerebellum. Other parts of the brain are involved in the movement coordination process, but the cerebellum is responsible for most of this function along with posture and balance. When the cerebellum becomes damaged due to excessive pressure, the individual will have trouble with controlling the position of their legs, arms, and posture. Individuals affected by Chiari malformation can sustain extensive damage to parts of their cerebellum as it inappropriately extends down into the increasingly narrow spinal canal. The medical terms used to describe these problems with coordination are known as dysmetria and ataxia. Poor coordination may or may not be isolated to a patient's posture and limbs when it is caused by Chiari malformation.
