Introduction[edit | edit source]
The word Chorea has Greek origins meaning "to dance". It has a dance-like appearance due to the random and flowing quality of the movement. Chorea is a type of hyperkinetic movement disorder. The involuntary movements flow from one body area to another which cannot be predicted beforehand.
Causes[edit | edit source]
They are predominantly of 2 types
- Acquired Causes
- Genetic Causes
Phenomenological Features[edit | edit source]
- Flowing Quality
- Parakinesia-Patients blend their chorea induced movements with their own normal movements.
- Motor impersistence- patient is unable to perform sustained motor activities.
- Ballism- Variant of chorea which shows large-amplitude flinging movements involving proximal extremities.
- Athetosis-Slow writhing movements involving distal limbs sometimes may be face.
- Varying velocity of movements-quick velocity and low- amplitude movements accompanied by jerks.
This video displays the dance-like movements performed by a patient.
