Intra-epidermal evoked potentials: A promising tool for spinal disorders?

The test–retest reliability of large and small fiber nerve excitability testing with threshold tracking

“…Furthermore, we do not have any evidence that our multipin stimulation electrodes preferentially activate A-delta fibers. Further studies are needed for this purpose comparing multipin electrode evoked potentials compared with laser evoked potentials similar to other studies compared intra-epidermal electrical stimulation with contact heat stimulation evoked potentials ( Lutolf et al, 2022 ) and electrical stimulation using a concentric planar electrode and laser stimulation using a CO2 laser stimulation ( Lefaucheur et al, 2012 ). Another limitation of our study is that small fibers frequently have habituation, which we unfortunately did not take into account in our study design.…”
