1. An impedance-EMG needle comprising:
a shaft configured to be inserted subcutaneously into tissue;
a plurality of current impedance electrodes, each current impedance electrode of the plurality of current impedance electrodes being disposed around the shaft; and
a plurality of voltage impedance electrodes, each voltage impedance electrode of the plurality of voltage impedance electrodes being disposed around the shaft between the plurality of current impedance electrodes; and
an active EMG electrode, disposed at a distal end of the shaft of the impedance-EMG needle, wherein the active EMG electrode is configured to enable simultaneous operation of the active EMG electrode with the plurality of current impedance electrodes and the plurality of voltage impedance electrodes.
