Branchial myorhythmia in a case of systemic lupus erythematosus

Myoclonus is characterized by sudden, brief, shock-like movements involving the extremities, face, and trunk [1]. Myoclonus is commonly classified into cortical, brainstem and spinal forms according to its presumed origin [2,3]. Myorhythmia has similar characteristics, but is distinguished from myoclonus by its rhythmicity (1 –4 Hz) and slower muscle contractions (~200 msec) [4].
