Programming of multichannel cochlear implants (CIs) requires subjective responses to a series  of sophisticated psychophysical percepts. It is often diffi cult for young prelinguistically deaf  children to provide adequate responses for device fi tting. This is especially true in setting levels  of maximum comfortable loudness, whereby failure to indicate growth of loudness may result  in elevation of stimulus levels to the threshold of pain. The acoustic or stapedial muscle refl ex  has been used previously to provide objective confi rmation of acoustic stimulation, and there  have been attempts to use the refl ex in hearing-aid fi tting. It has also been suggested that  electrically elicited middle-ear muscle refl exes [electrically evoked stapedial refl ex threshold  ( ESRT)] may have applicability in confi rming and quantifying electrical stimulation through a  CI. To assess the relationship between ESRT characteristics and levels of loudness perception  with CIs, determine the reliability of the response, and investigate the potential use of ESRT  in CI programming, 26 prelinguistically deafened CI users were evaluated. Refl exes have also  been attempted on 312 electrodes, with responses present in 213 (68.3%). Comfort levels  predicted by subjective judgments were highly correlated with the ESRT in individuals with CI.  ESRT provides an objective, accurate, and rapid method of estimating maximum comfortable  loudness levels, which may be useful in the initial programming of young implant recipients
