Axon-II: Delta NCS

Axon-II: Delta NCS

Identify the root cause of many common pain symptoms through a simple in-office test! Advanced technology accurately identifies the exact level and side of the nerve root cause of pain that is usually not detected during motor nerve studies performed with EMG/NCV.

Pinpoints the root cause of many pain symptoms associated with:

  • Back pain
  • Neck pain
  • Migraine pain
  • Hand pain
  • Foot pain
  • Shoulder pain
  • Chronic pain
  • Acute pain
  • Post Op pain

Features and Benefits
  • Patented electrical signal selectively stimulates A-Delta fibers.
  • Testing results and report provide doctor with clear explanation and show which specific nerve site and side of the body pathology exists.
  • Since the patient is his own control, independent of age or gender and population variables, the sensitivity approaches 96%.
  • A potentiometer reading verifies nerve firing by detecting the action potential at each testing site, ensuring clinical objectivity.
  • High potentiometer amplitudes have been reported to have a close correlation with high VAS ratings.
  • Can also test C and A-beta fibers, which is useful when RSD or sympathetically mediated pain syndrome is suspected.
  • Detect signs of sympathetic dysfunction with pain caused by an otherwise innocuous stimulus.
  • Detects down-regulated A-delta function to locate injured nerve(s) with statistical sensitivity approaching 100%.

Articles

Over 400 published studies support the basic science behind small pain fiber nerve conduction studies. Presently studies are underway at the University of California at Davis and Irvine (UCD and UCI) and the VA in Long Island and many others. The following studies performed with antecedent devices clearly show this technology is the Gold Standard in detecting pain fiber pathology. 

A-Delta Pain Fiber Nerve Conduction Study Benefits Patients with Spinal Pain
Of 151 pain fiber nerve conduction studies administered to patients with cervical and lumbar spinal pain, 56% changed treatment plans for the patient and 35% confirmed the planned treatment. In 8% of patients, the studies changed the side of the patient receiving treatment.

Predicting Nerve Root Pathology With Small Pain Fiber Nerve Conduction Studies (spf-NCS)
Axon-II shows 95% sensitivity in detecting pre-DRG pathology.

Using Axon-II to Target Transforamenal Blocks
Summary: Nerve conduction sensory (NCS) test helps to diagnose severity, location & distribution of radiculopathy or neuropathy. Non-invasive method. Measures sensory threshold using neuroselective frequency to test Type A-delta fibers. Abnormally high NCS measures indicate significant nerve conduction loss. Abnormally low NCS indicate hyperesthetic state that corresponds with inflamed, irritated or regenerating nerves.

Chronis Prostatitis Causing Pelvic Pain Due To Sacral Entrapment
Summary: Using the Axon-II, LSU Pain Center found the majority of fibromyalgia patients have previously undiagnosed nerve-root pathology. Ten of these treated patients were available for a one-year follow-up. All ten were found free of all Fibromyalgia symptoms.

A-delta Analysis Helps Identify Piriformis Syndrome
Summary: This retrospective study of 50 patients found an 80% probability of concomitant piriformis syndrome when the Axon-Il detected abnormal L5 and S1 dysfunction on the ipsilatyeral (same) side.
