A nerve monitoring device (10) is provided that includes a cannula and a sensor (14) for monitoring a nerve. The device can be inserted into an internal body space at a desired depth of insertion and at a desired rotational orientation to monitor the activity of the nerve and/or an associated muscle(s). At least one of the cannula (12), the sensor and a sensor support element (540) can be configured to enhance desired contact between the sensor and anatomic features, such as muscles, nerves or tissue, within the body space in an atraumatic manner. At least one of the sensor, cannula and support element can be reconfigurable from a first configuration to a different second configuration, where the second configuration conforms to the anatomical geometry of at least a portion of the body space so that the sensor satisfactorily contacts the target muscle(s) and/or nerve to monitor the same.
