In various examples, a stimulation needle apparatus is used for selectively administering a trial stimulation to body tissue of a patient. The stimulation needle apparatus includes a cannula assembly including a cannula and a cannula hub disposed at a proximal cannula end. A stylet assembly includes a stylet sized and shaped to fit within a cannula lumen. A stylet hub is disposed at the proximal stylet end and is configured to engage with the cannula hub. With the stylet hub engaged with the cannula hub, the distal stylet end extends distally from the distal cannula end. A stylet connection is electrically coupled with the stylet and is configured to electrically couple with a stimulator device, such that, a stimulation pulse delivered by the stimulator device is conducted from the stylet connection through the stylet to the distal stylet end to administer the trial stimulation.
