Uncoordinated movement is a muscle control problem or an inability to finely coordinate movements. This condition is called ataxia.
It leads to a jerky, unsteady, to-and-fro motion of the middle of the body (trunk) and an unsteady gait (walking style).
Smooth graceful movement requires a fine balance between different muscle groups. A part of the brain called the cerebellum manages this balance.
Diseases that damage the cerebellum, spinal cord, or peripheral nerves can interfere with normal muscle movement and result in coarse, jerky, uncoordinated movements.
Brain injuries or diseases that can cause uncoordinated movements include:
Poisoning or toxic effects caused by:
Other causes include:
Use safety measures around the home to make it easier to get around. For example, avoid clutter, leave wide walkways, and avoid throw rugs or other objects that might cause slipping or falling.
People with this condition should be encouraged to take part in normal activities. Family members need to be very patient with a person who has poor coordination. Take time to show the person ways to do tasks more easily. Take advantage of the person's strengths while avoiding his or her weaknesses.
Walking aids, such as a cane or walker, may be helpful.
Call your health care provider if:
In emergency situations, the patient will first be stabilized.
The health care provider will perform a physical exam and ask questions about the person's symptoms and medical history.
The physical exam will also include a detailed examination of the nervous system and muscles, paying careful attention to walking, balance, and coordination of pointing with fingers and toes. The patient will be asked to stand up with the feet together and the eyes closed. This is called the Romberg test. If the patient loses balance, this is a sign that the sense of position has been lost and the test is considered positive.
Medical history questions may include:
Tests that may be performed include:
You may need to be referred to a specialist for diagnosis and treatment. A home safety evaluation by a physical therapist may be helpful.
