An essential tremor most commonly affects which body part?

• A. Hands
• B. Face
• C. Legs
• D. Trunk

Answer: (A)

Essential tremor is a tremor that appears with posture or voluntary movement rather than at rest. The hands are the area most commonly affected, often bilaterally, making tasks like holding utensils, writing, or steadying a cup visibly tremulous. While the tremor can later involve other regions such as the head or voice, the hands remain the most frequent site across many patients. This pattern—hand-delonged, action/postural tremor—helps distinguish essential tremor from other tremor types, such as resting tremor seen in Parkinson disease. Therefore, the hands are the best answer because they are the most commonly affected part in essential tremor.
