Electrical Stapedius Reflex Test (ESRT)

An objective measure that can be useful in establishing a most comfortable level in children with cochlear implants who are unable to provide feedback to the audiologist about the loudness of sound. A small probe is placed in the opposite ear. The stimulation level of the implant is increased until a small muscle reflex is seen in the opposite ear. This muscle reflex is present in most people and occurs at a level that is loud, but still comfortable.
