Movement - uncoordinatedDefinition Uncoordinated movement is an abnormality of muscle control or an inability to finely coordinate movements, resulting in a jerky, unsteady, to-and-fro motion of the trunk or the limbs. Considerations Smooth graceful movement results from a fine balance between opposing muscle groups. This balance is coordinated by a portion of the brain called the cerebellum. Diseases that damage the cerebellum, spinal cord, and peripheral nerves (connecting the cerebellum to the muscle groups) can interfere with the fine tuning of muscular movement and result in coarse, jerky, uncoordinated movement. This condition is called ataxia, and is easily seen in the jerky, to-and-fro motion of the trunk and unsteady gait (walking style). Ataxia may appear as a congenital defect, or follow a simple viral infection such as chicken pox. It may also appear following encephalitis, head trauma, and diseases affecting the central nervous system or spinal cord. Appearance as a genetic disorder, or as a toxic reaction to drugs, medications, alcohol or environmental toxins is also possible. Common Causes
Home Care Take safety measures around the home to compensate for difficulties in mobility that are inherent with this problem. For example, avoid clutter, leave wide walkways, and avoid throw rugs or other objects that might cause slipping or falling. Other family members should encourage the affected person to participate in normal activities. Family members need to have extreme patience with people who suffer from poor coordination. Take time to demonstrate ways of performing tasks more simply, and taking advantage of the afflicted person's strengths while avoiding weaknesses. Call your health care provider if
What to expect at your health care provider's office The medical history will be obtained, and a physical examination performed. In emergency situations, the patient will be stabilized first. Medical history questions documenting uncoordinated movement in detail may include:
The physical examination may include detailed neurological and muscular examination. Diagnostic tests that may be performed include:
