简介：
Overview
This article presents a method for measuring nociceptive responses to mechanical pressure in the hind paw of mice using electronic von Frey measurements. This technique allows for rapid and precise assessment of changes in mechanical withdrawal thresholds before and after inflammatory interventions.
