A-DELTA fast pain fibers testing is non-invasive, painless, quick, easy to perform and can rule in or rule out nerve root involvement before the patient leaves your office with 95% sensitivity

How It Works

The AXON-II detects down-regulated A-delta function to locate injured nerve(s) with statistical sensitivity approaching 100%. The patented electrical signal selectively stimulates A-delta fibers. The highest amplitude causing an action potential indicates pathology. A potentiometer verifies firing by detecting the action potential. Since the patient is his own control, independent of age or gender and population variables, the sensitivity is as high as is possible. High potentiometer amplitudes have been reported to have a close correlation with high VAS ratings. The AXON-II can also test C and A-beta fibers, which is useful when RSD or sympathetically mediated pain syndrome is suspected.

Research & Statistics

Over 90% of A-delta fibers reach the sensory cortex so they should allow the patient to exactly localization of the source of pain, but injury causes A-delta fiber to become numb. They pretty much stop firing. leaving the patient to rely on poor localizing C-Fibers when attempting to localize the source of pain. This causes patients to localize pain as coming from referred locations; some even appear from the opposite side. This explains why so many patients have serious difficulty localizing the source of pain.

AXON II Benefits

• More accurate: AXON II has over 95% sensitivity as compared to EMG/NCV with only 29% sensitivity and 14.5% false positive findings
• AXON II tests the A-delta, the small fast pain fibers, which are the earliest indicators of injury and nerve damage
• Allows physician to locate the side, nerve root level and severity of injury
• The test is painless
• Fully interpreted report includes graphic representation of injured nerve(s)
• A full thoracic, upper or lower extremity test takes approximately 15 minutes
