Abstract
Standard clinical middle-ear muscle reflexes (MEMRs) are typically measured as a change in admittance for a single, 226-Hz probe tone in the presence of an eliciting stimulus. Alternatively, wideband MEMRs are measured as a change in reflectance for a wideband click probe in the presence of an elicitor. This study evaluated test-retest measures of MEMR thresholds and amplitude-intensity (A-I) functions across four measurement systems based on differences in sensitivity (i.e., thresholds, A-I slopes) and reliability. Ten normal-hearing adults participated in two sessions. MEMR thresholds and A-I functions were measured using two clinical systems (GSI, Titan) with two elicitors (2 kHz, broadband noise-BBN), and two wideband systems (Titan Research module, Custom Etymotic-based system). The 2-kHz elicitor yielded the highest thresholds overall. BBN elicitors produced similar thresholds across clinical and wideband systems. The broadband elicitor with the clinical systems produced the steepest A-I slopes, and the slopes were steeper overall for clinical versus wideband systems. In most conditions, no significant test-retest differences were observed for thresholds or AI-functions, but intraclass correlations were highest for the clinical system measures. MEMR measures made with current clinical systems using BBN elicitors may optimize sensitivity, reliability, and overall diagnostic value of such measures.
