Abstract
Seven normal healthy individuals were investigated to determine the effect of needle electromyography (EMG) on serum creatine phosphokinase (CPK) levels. No changes were noted as the result of EMG. Exercise resulted in increases serum CPK activity and persons with large muscle mass showed higher initial CPK levels.
