Dyskinesia
1. Difficulty in performing voluntary movements. The term dyskinesia is commonly used in relation to Parkinson's disease and other so-called extrapyramidal disorders. The word dyskinesia (dis-ki-ne´ze-a) is logically derived from two Greek roots: dys-, trouble + kinesis, movement = trouble moving. 2. The presence of involuntary movements, such as the choreaform movements seen in some cases of rheumatic fever or the characteristic movements of tardive dyskinesia. Some forms of dyskinesia are a side effect of using certain medications, particularly L-Dopa and, in the case of tardive dyskinesia, the anti-psychotics.
