It is generally accepted that EMG bursts <50\u2009milliseconds are pathological.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To reassess minimum physiological EMG burst duration.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Surface EMG was recorded from face, trunk, and limb muscles in controls (n = 60; ages 19\u201385). Participants were instructed to generate the briefest possible ballistic movements involving each muscle (40 repetitions) or, in muscles spanning joints, to generate rapid rhythmic alternating movements (20\u201330\u2009seconds), or both.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n We found no effect of age on EMG burst duration. However, EMG burst duration varied significantly between body regions. Rhythmic EMG bursts were shorter than ballistic bursts but only significantly so for lower limbs (\n P<\/jats:italic>\n <\u20090.001). EMG bursts of duration <50\u2009milliseconds were frequently observed, particularly in appendicular muscles.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n We present normal reference data for minimum EMG burst duration, which may assist clinical interpretation when investigating hyperkinetic movement disorders.<\/jats:p>\n
