ObjectiveTo establish a simple method of determining the appropriate stimulus intensity for studying the dipole moment in somatosensory evoked fields.MethodsIn 17 patients (20 hemispheres), the authors studied the relationship between the dipole moment and stimulus intensity, which was quantified using the threshold of thenar muscle twitch (TMT). The dipole moment was measured at 1.0, 1.5 and 2.0 TMT. Two measurements were obtained at 1.5 TMT to determine the procedure's margin of error.ResultsThere was no significant difference between the dipole moments measured at 1.5 and 2.0 TMT.ConclusionsSetting the stimulus intensity at 1.5 TMT or more ensures a consistent response.
