In the literature the prevalent until now opinion was that writer's cramp was a disturbance of psychic origin or an occupational neurosis. However, the authors treated successfully three cases of this syndrome with thalamotomy in the years 1976-1982. Two cases were in subject with right-handedness who had graphospasm with evidence of increasing difficulty in writing until complete impossibility of further writing, after several years postural and intentional tremor appeared, and dystonic symptoms developed in the right foot. The third cases had a history of 16 years of writer's cramp and after years symptoms of right-sided dystonia with involuntary movements of the right upper extremity and continuous tics and spams of the facial muscles. After thalamotomy in all cases writer's cramp, tremors and involuntary movements disappeared, writing became again possible and the efficiency of right extremities returned. The described cases of writer's clamp were focal forms of dystonia which became generalized after years. The indications to stereotaxic treatment in these syndromes should be established much earlier.
在文献中，迄今为止普遍的观点是书写痉挛是一种精神源性障碍或职业性神经症。然而，作者在1976年至1982年期间成功地用丘脑切开术治疗了三例这种综合征。两例患者为右利手，患有书写痉挛，有证据表明书写困难逐渐增加，直至完全无法继续书写，数年后出现姿势性和意向性震颤，右脚出现肌张力障碍症状。第三例有16年书写痉挛病史，数年后出现右侧肌张力障碍症状，右上肢有不自主运动，面部肌肉持续抽搐和痉挛。在所有病例中，丘脑切开术后书写痉挛、震颤和不自主运动消失，再次能够书写，右上肢功能恢复。所描述的书写痉挛病例是局限性肌张力障碍形式，数年后会发展为全身性。在这些综合征中，立体定向治疗的指征应更早确立。
