G4 Foot Drop System: Wearable FES Nerve & Muscle Stimulator for Natural Gait

Meet the G4 Foot Drop System—an advanced wearable Functional Electrical Stimulation (FES) solution designed to restore a more natural, confident walking pattern. Built for real-world use, this fourth-generation device blends medical-grade engineering with intuitive control to help people who experience foot drop due to stroke, nerve injury, spinal conditions, or other mobility limitations.

How it works

The G4 system uses MEMS sensor technology and patented AI-driven algorithms to continuously learn and adapt to your gait. By tracking swing angle and pace, it precisely times electrical stimulation to the nerves and muscles responsible for dorsiflexion and eversion. The common peroneal nerve, tibialis anterior, and related muscles receive targeted, mild electrical pulses during the swing phase, lifting the foot at the right moment for a smoother, safer stride. The result is a more natural walk with fewer trips and less fatigue, whether you’re navigating stairs, sidewalks, or uneven surfaces.

Key features that differentiate the G4

• Smart gait adaptation: AI-powered timing learns your gait pattern for personalized stimulation with every step.
• Precision electrodes: Medical-grade stainless steel electrodes with a patented sequential arrangement position stimulation exactly where it’s needed for reliable dorsiflexion.
• Clear visual interface: Crystal-clear OLED display and a durable IML touch panel make setup and monitoring effortless.
• Self-contained wearability: Fully portable, designed for clinic, home, or rehabilitation centers—no external boxes required.
• Clinical-grade reliability: CE and ISO13485 certified with Class II instrument classification, backed by a 2-year warranty.
• Proven lineage: The latest generation builds on years of clinical use and continual innovation in wearable FES technology.

Who can benefit

The G4 Foot Drop System is ideal for individuals experiencing foot drop due to stroke, incomplete spinal cord injuries, peripheral nerve injuries, or other neurological conditions that affect ankle dorsiflexion. It’s suitable for:

• Patients completing inpatient or outpatient rehabilitation
• Home-use programs guided by a clinician
• Clinics and rehabilitation centers seeking a reliable, ready-to-wear solution

Real-world use cases

Imagine walking from your living room to the kitchen without catching your toe on a rug; climbing stairs with steady clearance; or strolling outdoors without needing a brace. The G4 system supports activities like daily walking, grocery shopping, and light exercise—empowering independence while delivering therapy-grade stimulation that supports motor relearning and functional recovery.

What’s included and how to use

Designed for easy self-contained use, the device slips onto the leg with comfortable straps and places the electrode array around the targeted nerves. After a quick setup, the G4 automatically starts learning your gait and begins delivering synchronized pulses during the swing phase. For best results, follow clinician guidance on wearing duration, stimulation intensity, and progression of activity.
