Arrangements are described for fitting a cochlear implant to a recipient patient. An acoustic stimulus is delivered to an ear of the patient over a range of acoustic frequencies. A baseline acoustic transfer function resulting from the acoustic stimulus is measured using a response sensor configured to sense pressure response characteristics in the middle ear. And a maximum comfortable level (MCL) of stimulation is determined for at least one stimulation contact in the electrode array, based on performing an electrically evoked measurement to an electric stimulation signal and using the response sensor to measure a modified acoustic transfer function. The modified acoustic transfer function is compared to the baseline acoustic transfer function to determine when a stapedius reflex response occurs and identify the MCL.

Detection of electrically evoked stapedius reflex

A vestibular prosthesis system is described which includes an external movement sensor that is attachable a patient's head for generating an external movement signal. A fail-safe sensor is configured to detect movement of the one or more external movement sensors relative to the head and generate a corresponding relative motion signal. And an implant processor also is implantable under the skin and in communication with the fail-safe sensor and the external transmitter for generating an implant stimulation signal based on the external movement signal and/or the relative motion signal to electrically stimulate target neural tissue for vestibular sensation by the patient.

Vestibular implant system with internal and external motion sensors

A vestibular prosthesis system is described which includes an external movement sensor that is attachable a patient's head for generating an external movement signal. An internal movement sensor is implantable under the skin of the patient's head for generating an internal movement signal. A fail-safe sensor is configured to detect movement of the one or more external movement sensors relative to the head and generate a corresponding relative motion signal. And an implant processor also is implantable under the skin and in communication with the internal movement sensor and the external transmitter for generating an implant stimulation signal based on one of the movement signals and/or the relative motion signal to electrically stimulate target neural tissue for vestibular sensation by the patient.

A novel vestibular implant system is described. An implantable vestibular stimulator provides vestibular stimulation signals to stimulate target neural tissue for vestibular sensation by a patient. One or more motion sensors are controllably powered by the vestibular implant system and develop a motion signal reflecting head motion of an implant patient. The vestibular stimulator includes at least two different operating modes: i. a sensor controlled mode wherein the motion sensor is powered and the vestibular stimulation signal is developed as a dependent function of the motion signal, and ii. a sensor independent mode wherein the motion sensor is unpowered and the vestibular stimulation signals, if any, are developed independently of the motion signal.
