Which term describes involuntary muscle contractions causing twisting and repetitive movements?

• A. Dyskinesia
• B. Dystonia
• C. Bradykinesia
• D. Akinesia

Answer: (B)

Twisting, repetitive involuntary movements come from dystonia. Dystonia is caused by sustained or intermittent muscle contractions that produce abnormal postures and twisting motions. These contractions can affect a single body part (focal), larger regions (segmental), or the whole body (generalized), and they’re often triggered by movement or stress and may be relieved by rest or a sensory trick. Dyskinesia is a broader term for abnormal involuntary movements and can include various patterns such as chorea or dystonia, but the specific twisting postures and patterned movements described point to dystonia. Bradykinesia refers to slowness of movement, while akinesia means a difficulty initiating movement, neither of which describes involuntary twisting contractions.
