Synopsis

High-frequency (13-18 Hz) rhythmic contractions of the legs immediately after standing. There is often an associated sense of unsteadiness or discomfort with standing, and those affected may report a fear of falling. Symptoms improve with sitting or walking. Average age of onset is 50-60 years. The tremors are difficult to treat and progress over time, causing increasing disability.
