dystonic
Involuntary sustained contractions
Dystonic describes involuntary muscle contractions that cause twisting, repetitive movements or abnormal postures.
The term appears in medical contexts discussing dystonia, a neurological movement disorder: dystonic spasms, dystonic tremor.
A dystonic reaction may occur as a side effect of certain medications, particularly antipsychotics.
