Purpose : Primary writing tremor(PWT) can be classified as either type A or type B depending on whether tremor appeared during writing or whilst writing and also on adopting the hand postures normally used for writing. Through the clinical experience author has had an impression that PWT type B may not be purely dependant on specific writing postures. The objective of this study was to clarify whether PWT type B have writing posture-specificity or not. Results : The data indicated that type B PWT is not writing posture-specific. Various pronation and supination postures could evoke tremor as well as writing postures. Furthermore most of other pronation- and supination-related tasks could evoke tremors as well as action of writing. Conclusions : The present data suggest that PWT should be limited only on the pure form of task-spesific PWT type A.

저자들은 최근 글을 쓰는 자세에서는 진전이 나타나지 않고 글을 쓸 때에만 진전이 나타나는 전형적인 원발성 진전 A형을 경험하였기에 이를 보고하며, 본 증례를 통해 원발성 서자진전 A형은 표현 양상으로는 서로 다르나 병태생리적으로 서자경련과 유사한 질환임을 추정해 볼 수 있었다.
