Visualization of radial nerve activity at the upper arm using magnetoneurography.

ABSTRACT:

Objective

To evaluate the function of the radial nerve in the upper arm using Magnetoneurography (MNG).

Methods

Eight asymptomatic male volunteers (age 25-63 years) and one 67-year-old female patient with radial nerve palsy were included. The radial nerve was electrically stimulated in the right wrist, and the evoked magnetic field was recorded using a 132-channel bio-magnetometer system with a superconducting quantum interference device positioned below the upper arm. The measurements were divided into distal and proximal sessions because of the extensive range of the nerve.

Results

MNG recorded the radial nerve's evoked magnetic field in all cases, and the neural activity of the radial nerve at the upper arm was visualized using reconstructed currents. The mean cond
