Which tremor appears when maintaining a posture and can be seen in hyperthyroidism, anxiety, and benign essential tremor?

• A. Resting Tremor
• B. Postural Tremor
• C. Intention Tremor
• D. Orthostatic Tremor

Answer: (B)

Postural tremor is the tremor that appears when you hold a position against gravity, such as keeping the arms outstretched. It’s commonly seen in hyperthyroidism, in anxious states, and in essential tremor, where the tremor is present with sustained posture and often worsens with action. This type of tremor contrasts with resting tremor, which occurs when muscles are at rest (typical of Parkinson disease), and with intention tremor, which worsens as you approach a target during a purposeful movement and points to cerebellar issues. Orthostatic tremor happens specifically while standing and is characterized by a rapid tremor in the legs, not the usual pattern described here. Therefore, the described scenario fits a postural tremor.
