Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] . It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1][3] on one side of the body [4] and can cause significant disability. [5] .

About Ballism. General Information. Hemiballism involves involuntary, violent movements on one side of the body. They are especially violent because they involve the muscles where the limbs attach to the body. The most common cause is stroke or tumor. Symptoms

Aug 23, 2023 · Hemiballismus is a hyperkinetic involuntary movement disorder characterized by intermittent, sudden, violent, involuntary, flinging, or ballistic high amplitude movements involving the ipsilateral arm and leg caused by dysfunction in the central nervous system of the contralateral side.

Definition: Ballism is a rare movement disorder causing involuntary, flinging movements. Causes: It often results from brain damage due to stroke or traumatic injuries. Symptoms: Patients experience rapid, erratic motions primarily affecting one side.

Jan 21, 2025 · Ballism is a very severe form of chorea where a violent flinging of the extremities is observed. The movements are involuntary and usually involve the limbs. Ballismus is usually unilateral but, rarely, may be bilateral.
