RigiScan vs. the TechRing: Comparing Nocturnal Erection Measurement

Urologists have been interested to know how the FirmTech TechRing compares to the Rigiscan device. The RigiScan has been the old gold standard in clinical and legal settings, known for its precise nocturnal function measurements. Typically used in sleep labs, the RigiScan has played a pivotal role in post-prostate surgery evaluations and other erectile dysfunction diagnoses.

In a comparative analysis, Dr. Mohammed Nabil Amin, a renowned Egyptian urologist, examined both a RigiScan test and our FirmTech TechRing. By having patients wear both devices simultaneously, Dr. Amin was able to determine the correlation in data output.

RigiScan’s Methodology

This device takes four distinct measurements: two loops at the penis tip and two at the base, analyzing rigidity and tumescence. While this patient showed little variance, RigiScan can effectively showcase differences in cases of severe dysfunction or arterial blockages.

The Innovative FirmTech TechRing

Our FirmTech app leverages a pressure sensor and strain gauge within the TechRing, providing a comprehensive representation of nocturnal erections. This modern approach offers a less invasive and more accessible solution for tracking erectile health.

Comparative Analysis Results

Our juxtaposed graph images align the FirmTech app’s 0-10 scale with RigiScan’s 0-100, synchronizing timestamps. On May 14, 2025, both devices were worn for approximately seven hours. Although RigiScan and the TechRing utilize different algorithms, their results are remarkably consistent.

As the industry moves towards innovative solutions, FirmTech remains committed to providing reliable nocturnal erection monitoring tools, supporting both patients  and healthcare professionals.

By maintaining accuracy and embracing innovation, FirmTech offers a practical alternative to traditional urology tools like Rigiscan, further enhancing patient care. For more detailed information on our products, check out our TechRing Product Page.
