fitting measures offer a means to circumvent the subjectivity of cochlear implant programming, with the stapedius reflex representing one robust predictor of the maximum comfortable loudness level. With the present study, it was investigated whether long-term electromyographic measurements of the stapedius muscle using implanted electrodes are feasible....
No actionable change for current CI fitting practice; this is early-stage animal research establishing feasibility of long-term stapedius reflex recording, not yet validated in humans.
Objective, autonomous CI fitting could dramatically reduce the burden of manual audiological programming sessions and improve outcomes for patients with limited clinic access.
