Resting tremor
Tremor at rest
HP:0002322
What it means
A resting tremor occurs when muscles are at rest and becomes less noticeable or disappears when the affected muscles are moved. Resting tremors are often slow and coarse.
Resting tremor vanishes with active movement, but typically reappears after a few seconds when the arms are held outstretched (reemergent tremor). In Parkinson disease, rest tremor frequency is usually in the low to mid-range (3-6 Hz), and the amplitude is quite variable, from less than 1 cm to over 10 cm in width.
