What you should cover
Tremor is the most common involuntary movement encountered in clinical practice. It is an unintentional, rhythmic muscle movement that usually affects the hands but can also affect the arms, head, legs, and rarely the trunk. Essential tremor is the commonest form, but tremor may sometimes be a symptom of an underlying neurological disorder or a manifestation of systemic disease, and patients are often worried about a diagnosis of Parkinson’s disease.
Ask the patient for a description of the “tremor” and how it has progressed over time:
- You may find that the patient is describing a tic—a sudden, repetitive, non-rhythmic movement often involving a single muscle group.
- A tremor that appears first in one hand and subsequently the other, perhaps spreading to one or both legs, is suggestive of Parkinson’s disease.
- A tremor that appears in both hands symmetrically, perhaps also involving a head tremor or a tremulous voice, is suggestive of essential tremor.
Under which circumstances does it occur?
- A tremor that occurs at rest …
