Orthostatic Tremor: A Spectrum of Fast and Slow Frequencies or Distinct Entities?
“Slow tremor electromyography frequencies (<13 Hz) may characterize a substantial proportion of patients labeled as OT. These subjects may have greater gait involvement and higher likelihood of falls leading to earlier presentation to subspecialty care.”
“Arm tremor was present with weight bearing by leaning forward in all patients in whom this maneuver was performed. In each case, the tremor frequency in the arms was similar to the orthostatic frequency in the legs. Postural arm tremor across a spectrum of frequencies was seen in some patients of all three “
