To determine diurnal and day\u2010to\u2010day variation, muscle strength was measured 4 times during day 1 and once at day 2. <jats:italic>Results:<\/jats:italic> Knee extension strength decreased during the day in both patients and controls. Neither diurnal nor day\u2010to\u2010day variation of muscle strength was higher in patients compared with controls. <jats:italic>Conclusions:<\/jats:italic> Patients with mild to moderate MG did not have increased variation of isometric muscle strength during the day or from day\u2010to\u2010day compared with controls. This suggests that isometric muscle performance can be determined with high reproducibility in similar groups of MG patients without regard to time of day. <jats:italic>Muscle Nerve<\/jats:italic>
