Ultrasound-Guided Multi-Branch Rectus Femoris Nerve Block for Spasticity Assessment.

ABSTRACT: Background: Stiff-knee gait commonly involves rectus femoris spasticity in patients with central nervous system lesions. Diagnostic nerve blocks aid in predicting treatment outcomes; however, current techniques may overlook multiple nerve branches that innervate the rectus femoris muscle, potentially resulting in an incomplete assessment of treatment outcomes. Methods: We present an ultrasound-guided approach that we currently use in our practice, using anatomical landmarks, including the femoral artery, the sartorius muscle, and the rectus femoris' characteristic "J-shaped" internal tendon. The technique employs an "elevator" scanning method to identify all motor nerve branches (typically 2-3) entering the proximal third of the rectus femoris muscle. Each branch is blocked u
