Task-specific tremor is a kinetic tremor that appears or becomes exacerbated during highly skilled learned motor activities (1). This type of tremor is fre- quently denominated occupational tremor or focal tremor related to a particular action. The tremor usually occurs only when performing a specific repetitive task unique to each individual, but at times it may appear while performing similar movements and/or different activities that involve the same group of muscles. The tremor may be evident as soon as the patient initiates the specific activity or it may have a latency period of a few seconds to a few minutes after beginning the performance of the task.
