Abstract

A finite element method has been used to calculate the induced current flow in the spinal cord, when exposed to a time varying magnetic field. Results from the model explain why it is not possible to stimulate the descending motor tracts of the spinal cord with existing equipment. The specifications of a typical commercially available magnetic stimulator and the range of stimulating coils available are used to assess the feasibility of spinal cord stimulation
