Contraindications to anal sphincter EMG are similar to contraindications for performing limb or cranial EMG. EMG is usually contraindicated in persons receiving anticoagulant therapy. It also may be contraindicated in persons with extensive skin infections because of the risk of spreading infection from the skin to the muscle.

Other risks may exist, depending upon the specific medical condition (eg, edema, bleeding, burns) or surgical site.

EMG should not be performed from the site of anticipated muscle biopsy.
