ABSTRACT |
Abnormal writing can result from a large variety of neurologic disorders of motor control. Primary writing tremor(PWT) in its pure form denotes occurrence of a disabling tremor induced by writing alone. Therefore PWT is typical task-specific tremor. PWT could be classified as either type A or type B. In a strict sense, type B PWT is not pure form of PWT because it is not task specific. We describe a case of PWT type A. A 53-years-old right handed policeman complained of a 4 years history of shaking of his right had that interfered with writing. Tremor appeared during writing but not on adopting the hand position normally used for writing. |
