Felix NeuroAI treats tremor-related functional limitations in the upper limbs in adults with essential tremor. Minneapolis-based Fasikl designed its device as an alternative to interventions like deep brain stimulation (DBS) that require invasive procedures.

The non-invasive, wearable device connects to Fasikl’s cloud-based AI platform. It enables continuous brain-AI co-adaptation and personalized therapy. While worn on the wrist, the device uses the cloud to dynamically adjust stimulation. Fasikl says it offers all-day symptom relief while also fitting into the wearer’s lifestyle.

According to Fasikl, data from its TRANQUIL study supported the FDA clearance for Felix. Results showed that the Felix wristband significantly reduced tremors and displayed statistically and clinically significant improvement in the users’ ability to perform daily activities compared to those using a sham device. The study also saw consistent efficacy across demographics with no serious device-related adverse events reported.
