Measuring Neck Nerve Strain: An Experimental Investigation

We sought to determine the effects of head rotation, lateral neck flexion, and traction force on brachial plexus (BP) nerve strain, specifically at C5-C6 (Erb’s point), and C7, C8, and T1 roots in a multi-“filament” 3D model of the fetal BP. Using our constructed simulator and a tailored data acquisition system, strain readings were recorded and accurate to within
