Nerve conductions studies and needle electromyography are considered the gold standard of electrodiagnostic testing. However, the need for specialized equipment and personnel may limit the availability of electrodiagnostic testing for some patients. Portable devices have been developed to provide point-of-care nerve conduction studies. These portable devices have computational algorithms that are able to drive stimulus delivery, measure and analyze the response, and provide a detailed report of study results. Automated nerve conduction could be used in various settings, including primary care, without the need for specialized training or equipment. Proposed uses of automated nerve conduction devices include diagnosing carpal tunnel syndrome and diagnosing peripheral neuropathy, particularly in patients with diabetes.

Automated point-of-care nerve conduction tests currently being marketed include but are not limited to the following:

  • NC-stat® (NeuroMetrix)
  • NeuroMetrix ADVANCE™ (NeuroMetrix)
  • Axon-II™ (PainDx)
  • Neural-Scan™ system (NeuroDiagnostics)
  • Brevio® (Neurotron Medical)
  • VT 3000 (Virtual Medical Systems)
  • XLTEK Neuropath (Excel-Tec)
  • Cadwell Sierra (Cadwell Industries)
  • Cadwell Sierra Ascent (Cadwell Industries)
This policy is designed to address medical guidelines that are appropriate for the majority of individuals with a particular disease, illness, or condition. Each person's unique clinical circumstances may warrant individual consideration, based on review of applicable medical records.

Policy Position Coverage is subject to the specific terms of the member's benefit plan.

The use of automated point-of-care nerve conduction tests is considered EXPERIMENTAL/INVESTIGATIVE due to the lack of clinical evidence demonstrating improvement in health outcomes.
