To evaluate the measurement properties and clinical interpretability of the Japanese-language version of Cochlear™ Remote Check (J-RC) in cochlear implant (CI) users aged 15 years or older, including comparability with conventional hospital-based assessments, test-retest reliability, reproducibility across administration conditions, and factors affecting test completion and result interpretability.

Findings are too preliminary and context-specific (Japanese-language adaptation) to recommend broad practice change; clinics serving Japanese-speaking cochlear implant users should monitor this validation work before adopting J-RC as a routine remote monitoring tool.

Validating remote monitoring tools in non-English languages is critical for equitable, scalable cochlear implant care globally, and this is one of the first formal psychometric evaluations of Remote Check outside English-speaking markets.

1. 01Study evaluates the Japanese-language version of Cochlear's Remote Check (J-RC) system.
2. 02Focus is on measurement properties (reliability, validity) and clinical interpretability.
3. 03Published in Auris Nasus Larynx (2026); PMID 42119171.
4. 04Supports remote follow-up for cochlear implant users without requiring in-clinic visits.
5. 05Findings are specific to Japanese-speaking CI users and may not generalise broadly.
