about MUSC

Anal Sphincter EMG

Anal sphincter EMG is recorded with a small sponge electrode in the anal canal. The person relaxes, squeezes and pushes. A computer records sphincter muscle electrical activity.

Anal sphincter electromyography confirms the proper muscle contractions during squeeze and muscle relaxation during push. In people with non-relaxing puborectalis, the tracing of electrical activity gets bigger, instead of smaller, during a push.

Normal anal EMG activity with low anal squeeze pressures on manometry may indicate a torn sphincter muscle that could be repaired.
