Background: Orthostatic tremor is one of die few tremor conditions requiring an electromyogram for definitive diagnosis since leg tremor might not be visible to the naked eye. Phenomenology Shown: An iOS application (iSeismometer, ObjectGraph LLC, New York) using an Apple iPhone 5 (Cupertino, CA, USA) inserted into the patient's sock detected a tremor with a frequency of 16.4 Hz on both legs. Educational Value: The rapid and straightforward accelerometer-based recordings accomplished in this patient demonstrate die ease with which quantitative analysis of orthostatic tremor can be conducted and, importantly, detnonstrates the potential application of this approach hi the assessment of any lower limb tremor.
