Technical Specifications
LEONARDO Stapedius Reflex Detector is a PC-based system designed for precise monitoring of the stapedius muscle contraction. It features internal data storage and transfer capabilities, with a probe tone of 85dB SPL at 226Hz and precision of less than 0.01cc. The measuring range is from -0.50cc to 5.00cc, with a graphic display range from 0.30cc to -0.50cc. The reflex detector operates in real-time with contralateral reflex stimuli, covering frequencies from 125Hz to 8000Hz and a maximum stimuli intensity of 110dB HL.

Applications in Cochlear Implants and Hearing Aids
LEONARDO is used for mapping cochlear implants and fitting hearing aids. It helps identify minimum and maximum audibility thresholds, crucial for building a cochlear map. The stapedius reflex thresholds provide an objective measure for determining the electrical intensity needed for the most comfortable level (MCL), especially useful in children. The device allows specialists to objectively build the maximum profile of the map, which can also serve as a reference for the minimum threshold.

Objective Techniques and Limitations
The device supports objective techniques like evoked potentials of the nerve (ECAP), which are detectable in over 80% of patients. However, the objective evocation threshold often differs from the subjective one, necessitating supplementary subjective detection methods. The electrical threshold of the stapedial reflex (ESRT) is usable in about 60% of patients and provides a precise reference for maximum audibility thresholds.

LEONARDO Stapedius Reflex Detector Precise and reliable Light, portable with a contemporary design LEONARDO Stapedius Reflex Detector is a revolutionary PC based system designed to monitor with utmost precision the contraction of the stapedius muscle through a continuous recording that provides real-time variation, in volume, between the insertion tip and the eardrum. LEONARDO is a high-precision device for the cavity volumetric detection from -0,30cc to 5,00cc. The contraction of the stapedius muscle can be induced both with acoustic stimuli and with electric stimuli. LEONARDO Stapedius Reflex...
