Measuring Sound-Processor Thresholds for Pediatric Cochlear Implant Recipients Using Visual Reinforcement Audiometry via Telepractice

Abstract

Purpose The goal of this study was to test the feasibility of using telepractice for measuring behavioral thresholds (T levels) in young children with cochlear implants (CIs) using visual reinforcement audiometry (VRA). Specifically, we examined whether there were significant differences in T levels, test time, or measurement success rate between in-person and remote test conditions. Method Data were collected for 17 children, aged 1.1–3.4 years. A within-subject AB-BA (A, in-person; B, remote) study design was used, with data collection typically occurring over 2 visits. T levels were measured during each test session using VRA for one basal, middle, and apical electrode. Two additional outcome measures included test time and response success rate, the latter of which was calculated as the ratio of the number of electrode thresholds successfully measured versus attempted. All 3 outcome measures were compared between the in-person and remote sessions. Last, a parent/caregiver questionnaire was administered at the end of the study to evaluate subjective aspects of remote versus traditional CI programming. Results Results showed no significant difference in T levels between in-person and remote test conditions. There were also no significant differences in test time or measurement success rate between the two conditions. The questionnaires indicated that 82% of parents or caregivers would use telepractice for routine CI programming visits some or all of the time if the option was available. Conclusion Results from this study suggest that telepractice can be used successfully to set T levels for young children with CIs using VRA.
