Belly dancer's dyskinesia or diaphragmatic flutter (DF) is a rare condition characterized by repetitive involuntary contractions of the diaphragm. Also known as diaphragmatic myoclonus (DM), this disorder can manifest with involuntary movement of the abdominal wall and contraction of accessory respiratory muscles or respiratory myoclonus. Because of its variable presentation, diagnosis can often be difficult and delayed. This phenomenon is thought to be secondary to abnormal excitation of the phrenic nerve, via the central nervous system or along the nerve.Another possible mechanism is the irritation of the diaphragm itself. Diagnosis can be made with ultrasound, thoracic videofluoroscopy, or electromyography (EMG). Different pharmacologic and surgical therapies have been used in the past, but overall, there are no specific guidelines regarding treatment. In this report, we present a case of DF in a young female patient.
肚皮舞者运动障碍或膈肌扑动（DF）是一种罕见病症，其特征为膈肌反复不自主收缩。这种病症也被称为膈肌肌阵挛（DM），可表现为腹壁不自主运动以及辅助呼吸肌收缩或呼吸性肌阵挛。由于其表现多样，诊断往往困难且易延误。这种现象被认为是继发于膈神经通过中枢神经系统或沿神经的异常兴奋。另一种可能的机制是膈肌本身受到刺激。可通过超声、胸部电视透视或肌电图（EMG）进行诊断。过去曾使用过不同的药物和手术疗法，但总体而言，关于治疗尚无具体指南。在本报告中，我们介绍了一名年轻女性患者的膈肌扑动病例。
