Using the case records of Mayo Clinic patients, 121 patients with a diagnosis of benign fasciculations were identified. All had a normal neurological examination and normal electrophysiological studies, except for fasciculation potentials. Interviews by telephone were conducted 2 to 32 years after diagnosis. None of the patients developed symptomatic motor neuron disease. Forty individuals were in health care careers. A subset of 19 patients described acute onset of fasciculations following a viral infection. Benign fasciculations are not a preclude to progressive motor neuron disease.
通过梅奥诊所患者的病例记录，确定了121例诊断为良性肌束震颤的患者。除肌束震颤电位外，所有患者的神经系统检查和电生理研究均正常。在诊断后2至32年进行了电话访谈。没有患者发展为有症状的运动神经元病。40人从事医疗保健职业。19例患者的一个亚组描述了病毒感染后肌束震颤急性发作。良性肌束震颤并非进行性运动神经元病的先兆。
