What can dyskinesia often result in?

Dyskinesia refers to a category of movement disorders that are characterized by involuntary, uncontrolled movements. This can manifest in various forms, such as twisting, jerking, or repetitive motions. The term itself is derived from the inability to control muscle movements effectively, which leads to these abnormal involuntary actions.

In many cases, dyskinesia can be a side effect of certain medications, especially those used to treat conditions like Parkinson's disease. While these medications aim to control symptoms and improve muscle movement, dyskinesia is often a paradoxical response where the treatment results in the opposite effect, leading to uncontrolled muscle movements.

The other options relate instead to controlled movement, coordination, and improved strength, which do not accurately describe the nature of dyskinesia. Therefore, the appropriate response highlights the essence of dyskinesia as resulting in uncontrolled muscle movements.
