Evidence Bar “Favorable” rating from ECRI report indicates UltraGuideCTR is safe and improves functional status in patients with carpal tunnel syndrome

Eagan, Minn., June 7, 2024 — Sonex Health, Inc. and The Institute of Advanced Ultrasound Guided Procedures announced today that ECRI completed a Clinical Evidence Assessment of its UltraGuideCTR™, with an Evidence Bar rating of “Favorable.” The ECRI Evidence Bar is a visualization of the organization’s judgment about the balance of benefits and harms of technology after assessing the available published clinical evidence in light of key outcomes and comparisons of interest. ECRI’s Clinical Evidence Assessment concluded that UltraGuideCTR is safe and improves functional status and symptom severity in patients with carpal tunnel syndrome (CTS), based on consistent findings from one randomized controlled trial and eight before-and-after studies reported in 11 publications. The full report is available to ECRI members.  

“The ECRI Evidence Bar Favorable rating is a significant milestone supporting the safety and effectiveness of UltraGuideCTR,” said Sonex Health CEO Bob Paulson. “This report provides payers and healthcare providers with access to a valuable summary of the breadth and depth of the UltraGuideCTR clinical outcomes data.” 

More than 31,000 carpal tunnel release with ultrasound guidance (CTR-US) procedures have been performed by over 200 physicians in 41 states, with another 52 physicians actively training to perform these procedures. In addition, more than 800 hand surgeons have participated in a variety of educational program opportunities sponsored by Sonex Health and The Institute of Advanced Ultrasound Guided Procedures, including a first-of-its-kind MSK Ultrasound Forum that brought together over 100 hand surgeons for hands-on training and peer-to-peer conversations.

The compelling and consistent clinical safety and effectiveness data for CTR-US procedures with the UltraGuideCTR device further supports its widespread use among physicians. Sixteen peer-reviewed publications have reported clinical results on more than 1,300 patients and 1,700 wrists, including a high percentage of simultaneous bilateral procedures. Patients consistently return to normal activities and work in three to five days as compared to weeks or months reported following traditional surgical CTR procedures.

“Applying ultrasound to perform carpal tunnel release procedures improves the clinical diagnostic and treatment pathway for both patients suffering from CTS and their physicians,” said Dr. Kevin Chung, professor of plastic surgery and chief of hand surgery at the University of Michigan. “The clinical and economic value of this proven, innovative ultrasound-guided technology benefits patients, their physicians, and the healthcare system.”
