Comprehensive auditory rehabilitation in adults receiving cochlear implants: A pilot study

OBJECTIVE: In the United States, most adults who receive cochlear implants (CIs) do not undergo a comprehensive auditory rehabilitation (CAR) approach, which may result in suboptimal outcomes. The objectives of this pilot study were to demonstrate that a CAR approach incorporating auditory training (AT) by a speech‐language pathologist (SLP) is feasible in adults receiving CIs and to explore whether this approach results in improved outcomes. METHODS: Twenty‐four postlingually deaf adult CI candidates were serially assigned to one of three groups: (a) a “CAR group” that received standard of care implantation, programming by an audiologist, an additional preoperative counseling session, and eight one‐hour AT sessions; (b) a “passive control” standard‐of‐care group; and (c) an “active control” group that also received the extra preoperative counseling session. Participants were tested preoperatively and 1, 3, and 6 months after CI using measures of word and sentence recognition in quiet and in babble, as well as measures of quality of life (QOL). RESULTS: The CAR approach was feasible, but this pilot study was underpowered to determine efficacy. Differential time courses of speech recognition improvement were seen for sentence and word recognition. All QOL measurements showed improvement from pre‐CI to 1 month post‐CI activation. Results revealed issues to consider for a larger‐scale study of CAR revolving around participant selection, study measures, and sample size. CONCLUSION: The CAR approach is feasible in new CI users. A larger trial is needed to investigate whether CAR leads to better outcomes or faster improvement in this clinical population. LEVEL OF EVIDENCE: 2.
