Tremor and Other Hyperkinetic Movements

“Spooning”: A Subtle Sign of Limb Dystonia

Christine Y. Kim, Elan D. Louis

Abstract


Background: The diagnosis of dystonia can be clinically challenging due to its heterogeneous presentation; essential tremor (ET) is a more common neurological disorder, but may be mimicked by other movement disorders, including dystonia, leading to misdiagnosis.

Phenomenology Shown: In three patients with hand tremor, two with prior diagnoses of ET, we present examples of “spooning” of the hands, characterized by wrist flexion and metacarpophalangeal hyperextension.

Educational value: Subtle dystonic features such as “spooning” may be present during the evaluation of patients with tremor and aid in the diagnosis of dystonia.
