Different types of myoclonus also share similar phenomenological characteristics that can be difficult to distinguish solely based on clinical exam.

The methodology and technical considerations for the electrophysiologic assessment of jerk\u2010like movements are reviewed. A simplistic pragmatic approach for the classification of myoclonus and other jerk\u2010like movements based on objective electrophysiologic characteristics is proposed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Clinical neurophysiology is an underutilized tool in the diagnosis and treatment of movement disorders. Various jerk\u2010like movements have distinguishing physiologic characteristics, differentiated in the milliseconds range, which is beyond human capacity. We argue that the categorization of movement disorders as myoclonus can be refined based on objective physiology that can have important prognostic and therapeutic implications.<\/jats:p>\n
