Neurotron brain etc

Introduction and Background

Neurotron, Inc. is a U.S.-based medical technology company specializing in electrophysiological diagnostic equipment. Founded in the early 1980s and headquartered in Colorado, the company pioneered the development of Current Perception Threshold (CPT) technology for quantitative sensory testing. For over four decades, Neurotron has supplied hospitals, research institutions, and clinics worldwide with devices designed to evaluate sensory nerve function accurately and non-invasively.

Technology and Principle (sNCT / CPT)

At the core of Neurotron’s innovation lies the Selective Current Perception Threshold Test (sNCT or CPT) method. This approach delivers precisely controlled sinusoidal electrical stimuli of different frequencies to selectively activate and measure three types of sensory nerve fibers: large myelinated Aβ fibers, medium Aδ fibers, and small unmyelinated C fibers. The device records the threshold at which the subject perceives current, providing a quantitative measure of sensory function or impairment. The test is fully automated, painless, and reproducible—making it suitable for both clinical and research applications.

Main Products and Accessories

The flagship product, the Neurometer® CPT®, is available in several models (including the NS3000). It enables standardized CPT measurements across multiple anatomical sites. The company also manufactures accessories such as disposable surface electrodes, connection cables, portable printers, and specialized data management software. These tools allow clinicians to perform detailed sensory evaluations while minimizing operator error. Product documentation highlights automatic calibration, user-friendly operation, and compatibility with digital data systems.

Clinical and Research Applications

The Neurometer CPT has been widely used in clinical studies and scientific research. Numerous publications have evaluated its role in diagnosing and monitoring peripheral neuropathies, including diabetic neuropathy, radiculopathy, and vibration-induced nerve injuries. Studies suggest CPT testing can detect early functional changes in sensory nerves and sometimes demonstrates higher sensitivity than traditional tools like monofilament or vibration testing. However, researchers note that CPT should be used as a complementary diagnostic method, interpreted alongside neurological examination and patient history.

Regulatory Status and Certifications

Neurotron’s CPT systems have received regulatory clearance from the U.S. Food and Drug Administration (FDA) under the 510(k) process. The company’s first approvals date back to the 1980s, confirming compliance with key safety and performance standards. This regulatory background enhances the device’s credibility and facilitates its acceptance in international medical markets.

Global Distribution and Support

Neurotron operates through a network of international distributors covering North America, Europe, Asia, and other regions. Authorized distributors provide product sales, operator training, maintenance, and calibration services. For buyers in the Middle East or Iran, verifying the presence of an official distributor or support center is essential prior to procurement—especially for regulatory documentation, import permits, and after-sales service arrangements.

Advantages, Limitations, and Practical Considerations

Advantages:

• Selective evaluation of different sensory fiber types (Aβ, Aδ, C)

• Quantitative, objective, and reproducible results

• Non-invasive and painless procedure

• Backed by decades of clinical use and research literature

Limitations:

• As with all diagnostic tools, CPT results should be interpreted in the context of full clinical evaluation

• Some variability may occur based on patient factors and electrode placement

• It is considered an adjunctive test, not a complete replacement for other diagnostic modalities

Practical Notes (for importers and clinicians):
Before purchasing or importing, ensure that a regional distributor exists to provide training, consumables, technical support, and repair services. Regulatory compliance with local medical device authorities should also be verified, as importation typically requires official certification, manuals in the local language, and proof of FDA or CE approval.

Conclusion

Neurotron, Inc. remains one of the most recognized names in quantitative sensory testing, with its Neurometer® CPT® serving as a benchmark for evaluating sensory nerve function. The device offers precision, non-invasiveness, and decades of research validation. Nevertheless, like any diagnostic instrument, its true value lies in appropriate clinical use, proper interpretation, and reliable technical support.
