Wolfe J, Gifford R, Schafer E. Measurement of the Electrically Evoked Stapedial Reflex Response with Wideband Acoustic Reflectance Measurement. Journal of the American Academy of Audiology. 2018 Apr;29(29). 337-347. PMID: 29664726 [PubMed]
The electrically evoked stapedial reflex threshold (ESRT) has been shown to be a good predictor of upper stimulation level for cochlear implant recipients. Previous research has shown that the ESRT may be recorded at lower stimulation levels and with a higher incidence of success with the use of higher frequency probe tones (e.g., 678 and 1000 Hz) relative to the use of the conventional 226-Hz probe tone. Research has also shown that the acoustic reflex may be recorded at lower stimulus levels with the use of wideband reflectance when compared to the acoustic reflex threshold recorded with a conventional acoustic immittance measurement.
