Jerky body movement is a condition in which a person makes fast movements that they cannot control and that have no purpose. These movements interrupt the person’s normal movement or posture.
The medical name of this condition is chorea.
Chorea; Muscle – jerky movements (uncontrolled); Hyperkinetic movements
This condition can affect one or both sides of the body. Typical movements of chorea include:
Bending and straightening the fingers and toes
Grimacing in the face
Raising and lowering the shoulders
These movements do not usually repeat. They can look like they are being done on purpose. But the movements are not under the person’s control. A person with chorea may look jittery or restless.
There are many possible causes of unpredictable, jerky movements, including:
Anti-cardiolipin antibody syndrome
Benign hereditary chorea (a rare inherited condition)
Disorders of calcium, glucose, or sodium metabolism
Medicines (such as levodopa, antidepressants, anticonvulsants)
Polycythemia rubra vera
Pregnancy (chorea gravidarum)
Systemic lupus erythematosus
Tardive dyskinesia(a condition that can be caused by medications such as antipsychotic drugs)
Other rare disorders
What to expect at your health care provider’s office
The doctor will perform a physical exam. This may include a detailed examination of the nervous and muscle systems.
The doctor will ask about your medical history and symptoms, including:
- What kind of movement occurs?
- What part of the body is affected?
- What other symptoms are there?
- Is there irritability?
- Is there
- Is there
- Are there emotional problems?
- Are there
Tests that may be ordered include:
- Blood tests such as
metabolic panel, complete blood count(CBC), blood differential CT scan of the heador affected area EEG(in rare cases) EMGand nerve conduction velocity(in rare cases)
- Genetic studies
Lumbar puncture MRI of the heador affected area Urinalysis
Treatment is based on the type of chorea the person has. If medicines are used, the health care provider will decide which medicine to prescribe based on the person’s symptoms and signs.
Treatment is aimed at the cause of the movements.
If the movements are due to a medicine, the medicine should be stopped, if possible.
If the movements are due to a disease, the disorder should be treated.
For people with Huntington disease, if the movements are severe and affect the person’s life, medicines such as tetrabenazine may help control them.
Excitement and fatigue can make chorea worse. Rest improves chorea. Try to reduce emotional stress.
Safety measures should also be taken to prevent injury from the involuntary movements.
