Abstract：
OBJECTIVE: Musician\'s focal hand dystonia is a painless task-specific focal dystonia, which presents with involuntary movements, abnormal postures, and loss of fine motor dexterity. We report here the case of a 63-year-old male, percussionist, with african ethnicity, with musician\'s focal hand dystonia who was treated with botulinum toxin, and describe the results at 4-weeks follow up.
METHODS: Clinical examination and video analysis revealed abnormal flexion of the 3rd finger, followed by flexion of the 4th and 5th fingers while playing the congas. Based on these findings, a diagnosis of musician\'s focal hand dystonia was established. Ten units of botulinum toxin were injected into the muscle fibres of the flexor digitorum superficialis corresponding to the 4th finger using electromyography and ultrasound guidance. Four weeks later, the patient reported a subjective 60% improvement in his performance. He emphasized the effect of botulinum toxin on performance speed and tension over the forearm and hand.
CONCLUSIONS: Botulinum toxin is not a definitive treatment for musician\'s focal hand dystonia, but it may potentiate other definitive rehabilitation techniques. More research is needed to determine the long-term effects of botulinum toxin on function enhancement in musician\'s focal hand dystonia.

摘要：
目的：音乐家的局灶性手部肌张力障碍是一种无痛的任务特异性局灶性肌张力障碍，表现出非自愿的运动，异常姿势,和精细运动灵巧的损失。我们在这里报道一个63岁的男性，打击乐手,非洲种族，音乐家的局灶性手部肌张力障碍接受了肉毒杆菌毒素治疗，并描述4周随访时的结果。
方法：临床检查和视频分析显示第3指弯曲异常，在演奏康加斯时，第四和第五手指弯曲。基于这些发现,音乐家的局灶性手部肌张力障碍的诊断建立。使用肌电图和超声引导，将十个单位的肉毒杆菌毒素注射到与第4指相对应的指浅屈肌纤维中。四周后,患者报告主观表现改善了60%.他强调了肉毒杆菌毒素对前臂和手部表现速度和张力的影响。
结论：肉毒杆菌毒素不是音乐家局灶性手部肌张力障碍的最终治疗方法，但它可能会增强其他明确的康复技术。需要更多的研究来确定肉毒杆菌毒素对音乐家局灶性手部肌张力障碍功能增强的长期影响。
