Neurometer CPT tests are painless and may be conducted anywhere on the body - including the most distal cutaneous finger and toe sites permitting the earliest possible detection of sensory nerve damage resulting from conditions such as diabetes, carpal tunnel syndrome, spinal injury, sciatica, and radiculopathy. This is an improvement over traditional electro-diagnostic and biopsy procedures performed for the past 60 years. This advance in technology permits measures not effected by skin temperature, edema or electromagnetic interference. More than 800 peer-reviewed research publications document the high sensitivity, specificity and intra-rater and inter-rater reliability of the Neurometer sensory nerve tests and their advantages over traditional procedures. No other functional clinical sensory diagnostic test provides more information. The CPT evaluation is also routinely employed for pharmaceutical and cosmetic development. Additionally, Neurometer CPT technology permits atraumatic non-injurious laboratory animal sensory evaluations.
