This short communication article was intended to update the utility and application of current perception threshold (CPT) testing in evaluation of people with neuropathy through an evidence-informed overview. Limited number of studies reported on the use of CPT in trigeminal neuralgia, diabetic peripheral neuropathy, myelo-optic neuro-pathy, post-herpetic neuralgia and uremic neuropathy. CPT was advantageous compared to nerve conduction studies due to its fiber-specific diagnostic properties, acceptable reliability and excellent validity for a myriad of peripheral neuropathic conditions.
