INRLGII Patents Low-Cost Neurostimulator

The National Institute of Rehabilitation Luis Guillermo Ibarra Ibarra (INRLGII) has secured patent No. 426001 for a noninvasive functional electrical stimulator developed by its team of physicians and engineers. The device, validated in Mexico, aims to expand access to neurological rehabilitation by offering a production cost up to 60% lower than imported equivalents.

Commercial neurostimulators can cost about MX$500,000 (US$25,000), while the INRLGII version is produced for about MX$200,000 (US$10,000). According to Jorge Airy, Medical Sciences Researcher, INRLGII, the institute combined engineering expertise with clinical knowledge to design the technology, protocols, and interventions.

The device sends electrical impulses to paralyzed muscles to execute specific functional movements, such as lifting a foot while walking or opening a hand to grasp an object. Completing a movement with stimulation enhances brain feedback, improving motor control and accelerating recovery. The stimulator has been used successfully in 20 patients at the institute.

Clinical evidence suggests greater effectiveness when therapy begins within weeks or months after a stroke. Jimena Quinzaños, Head of the Neurological Rehabilitation Division, INRLGII, says that the goal was to create a Mexican alternative with the same benefits as commercial brands.

The project supports the 2025-2030 National Development Plan by promoting technological sovereignty, replacing imports, and ensuring accessible equipment, says Carlos Pineda, Director General, INRLGII. He adds that the development responds to the challenge of equipping hospitals nationwide and strengthens national health and scientific objectives.

This is the sixth patent obtained by INRLGII. The institute says that the development reflects its mission to align cutting-edge research with real public health needs, offer treatments at no cost, and advance toward healthcare sovereignty.
