Musicians' dystonia is an occupational focal dystonia affecting men more often than women.
We identified all patients presenting with musicians' dystonia and prospectively collected data on reproductive and menstrual history from the women with musician's dystonia and female musicians without dystonia.
149 men and 23 women (13.37%) with musician's dystonia where identified. We did not identify any effect of contraceptive hormones, pregnancy, or menstrual phases on dystonia symptoms, but as compared with women without dystonia, those with musician's dystonia reported oligomenorrhea and menometrorrhagia significantly less frequently.
Our data reinforce the relation between sex hormones variations and musicians' dystonia. This link should be further explored to identify mechanisms and assess whether certain hormonal interventions might protect from the manifestation of dystonia.
音乐家肌张力障碍是一种职业性局灶性肌张力障碍，男性比女性更易受累。
我们识别出所有患有音乐家肌张力障碍的患者，并前瞻性收集了患有音乐家肌张力障碍的女性以及无肌张力障碍的女性音乐家的生殖和月经史数据。
共识别出149名男性和23名（13.37%）患有音乐家肌张力障碍的女性。我们未发现避孕激素、怀孕或月经周期对肌张力障碍症状有任何影响，但与无肌张力障碍的女性相比，患有音乐家肌张力障碍的女性报告月经过少和月经过多的频率明显更低。
我们的数据强化了性激素变化与音乐家肌张力障碍之间的关系。应进一步探索这种联系，以确定其机制，并评估某些激素干预措施是否可能预防肌张力障碍的表现。
