Urokinase-type Plasminogen Activator-induced Mouse Back Pain Model

Overview

This protocol outlines a non-invasive method to induce chronic back pain in mice for up to 10 weeks, which can be performed quickly and reliably with minimal training. The technique focuses on recognizing the difference between injecting ligament and muscle.
