A systematic review with meta-analysis of the diagnostic test accuracy of pedicle screw electrical stimulation

ConclusionElectrical stimulation of the pedicle screw can be used as an adequate diagnostic capability at the lumbar level with a threshold of 8  mA. However, thoracic stimulation is currently not reliable, with very low sensitivity and diagnostic validity at 6 mA or higher.
