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. [ http://www.ncbi.nlm.nih.gov/pubmed/22675666 https://orcid.org/0000-0002-0736-9199 ]

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.
