Abnormal posturing

Considerations:
Abnormal posturing is a sign of serious central nervous system damage.

Normally, when a muscle contracts, the muscles on the opposite side of the joint provide some resistance to contraction. Abnormal posturing occurs when damage to the central nervous system (brain or spinal cord) results in complete or partial lack of opposition to muscle contraction in various muscle groups.

See the following types of abnormal postures:

An affected person may alternate between different postures as his or her condition fluctuates.

Injury or inflammation of a portion of the brain, spinal cord, or nervous system is the most common cause of abnormal posturing. The particular type of posturing can reflect the type and area of nervous system involvement.

Common Causes:

Note: There may be other causes of abnormal posturing. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as quality, time course, aggravating factors, relieving factors, and associated complaints.

What to Expect:
Emergency measures may be begun immediately, including placement of an artificial airway (breathing tube) and assistance with breathing. The person will likely be hospitalized and in intensive care.

The medical history will be obtained from family members and a physical examination will be performed.

  • other
    • What other symptoms preceded or accompanied the abnormal posturing?
