Generalised, multifocal or segmental idiopathic torsion dystonia (ITD), is caused by an autosomal dominant gene with reduced penetrance in about 85% of cases. Of 104 patients with these types of ITD, 17 (16.4%) gave a history which suggested that dystonic movements had been precipitated or exacerbated by trauma. Eight of these 17 patients had affected relatives. If precipitated, dystonia appeared first in the injured part of the body within days or up to 12 months after the trauma and later became more widespread. Peripheral injuries may influence basal ganglia function and provoke the onset of dystonic movements in individuals who are ITD gene carriers.
全身性、多灶性或节段性特发性扭转性肌张力障碍（ITD）由常染色体显性基因引起，在约85%的病例中其外显率降低。在104例这类ITD患者中，17例（16.4%）有病史提示肌张力障碍性运动由创伤诱发或加重。这17例患者中有8例有患病亲属。如果是由创伤诱发，肌张力障碍在创伤后数天至12个月内首先出现在身体受伤部位，随后范围逐渐扩大。外周损伤可能影响基底神经节功能，并促使ITD基因携带者个体出现肌张力障碍性运动。
