title: Effect of electromyography on serum creatine kinase values in clinically normal dogs and horses.
abstract: The effect of needle electromyography (EMG) on serum creatine kinase (CK) activity was determined, using clinically normal dogs (males and females; n = 8) and horses (females; n = 8). All animals appeared normal on EMG evaluation. Serum CK was measured before and 4, 24, and 48 hours after EMG. Except for a single 24-hour sample in a dog, the animals did not have abnormally increased serum CK activity after EMG. For dogs and horses, mean values were increased, but within normal range at 4 and 24 hours and returned to base-line values by 48 hours after EMG. For dogs, but not for horses, these CK increases at 4 and 24 hours were significant (P less than 0.05). Most dogs and horses, without neuromuscular disease, did not have serum CK activity above the normal range after EMG.
