The present technology relates generally to the field of electrophysiology and specifically to automated devices, components, systems, and related methods for monitoring potential injury to the nervous system using evoked potentials during intraoperative neurophysiologic monitoring.

A surgical instrument assembly has (i) a surgical instrument including a handpiece and a probe or horn attached to the handpiece, (ii) a source of ultrasonic vibratory energy operatively connected to the probe or horn, (iii) a source of electrical current operatively connected to deliver electrical current to organic tissues of a patient at a surgical site contacted by a distal end of the probe or horn, and (iv) a sensor of electrical potential disposable in contact with the patient at a desired distance from the surgical site. The sensor is operatively connected to the source of ultrasonic vibratory energy to automatically attenuate an output thereof in response to a detected potential of a predetermined magnitude.

Systems and methods for enhanced hearing protection and data recording are disclosed. Recorded data is analyzed to determine user compliance with standard operating procedures. Additionally, hearing loss is monitored using neurological response of the auditory system to environmental noise. Optional sensors such as temperature sensors, accelerometers, GPS sensors are used to correlate noise data with external events. An optional acoustic source may be used to identify unusual conditions such as ear drum perforations and capture information related to health of the tympanic membrane and external auditory meatus. The systems and methods may also be used to protect the hearing and utility of military working dogs.

A sensing electrode selection algorithm is disclosed for use with an implantable pulse generator having an electrode array. The algorithm automatically selects optimal sensing electrodes in the array to be used with a pre-determined stimulation therapy appropriate for the patient. The algorithm preferably senses stimulation artifacts using different sensing electrodes, and more specifically different sensing electrode pairs as is appropriate when differential sensing is used. The algorithm further preferably senses these stimulation artifacts with the patient placed in two or more postures. The algorithm processes the stimulation artifact features measured at the different sensing electrodes and at the different postures to automatically determine one or more sensing electrode pairs that best distinguishes the two or more postures given the prescribed stimulation therapy.

Methods and systems for providing closed loop control of stimulation provided by an implantable stimulator device are disclosed herein. The disclosed methods and systems use a neural feature prediction model to predict a neural feature, which is used as a feedback control variable for adjusting stimulation. The predicted neural feature is determined based on one or more signals from an accelerometer configured in contact with the patient. The disclosed methods and systems can be used to provide closed loop feedback in situations, such as sub-perception therapy, when neural features cannot be readily directly measured.
