Abstract: A stimulation electrode assembly configured to be positioned relative to a patient for an operative procedure is disclosed. An evoked stimulation response may be sensed by a sensor near a portion of a subject. The evoked response may be sensed by an electrode and determined with a monitoring system. The evoked response may additionally and/or alternatively be sensed with a motion sensor. A position sensor may be provided to measure or determine whether the sensor has moved during a procedure.

Abstract: Aspects of the disclosure include a bio-electric stimulation probe assembly including a patch including a first aperture and also a guide socket including a grommet and a second aperture. The guide socket is positioned on the patch such that the first and second apertures are aligned. The assembly further includes a guide including a tip that is positioned within and rotatable within the grommet. A probe of the assembly having at least one electrode is interconnected with the guide and extends through the first and second apertures. The guide and guide socket are collectively arranged and configured so that the guide has three degrees of rotational freedom with respect to the grommet thus meaning the probe correspondingly has three degrees of rotational freedom with respect to the grommet. Methods of using stimulation probe assemblies are also disclosed.
