STEP BOOSTER
Walk with Confidence
A detachable, portable powered assist device that attaches to existing passive leg orthoses (AFO, KAFO, etc.) to provide walking assistance.
Key Functions & Features
Excellent Compatibility
A modular system attaches to a wide range of existing orthoses — AFO, KAFO, HKAFO, and orthopedic shoes — and works on either leg.
AI-Personalized Assistance
AI analyzes the user's gait characteristics and calculates the optimal assistive force for each individual, delivered via a tendon-driven mechanism (gait detection → assist force calculation → tendon-driven assistance).
Portable & Lightweight
Under 600g (excluding battery) and 100×120×45mm in size. The detachable structure means it's worn only when needed, minimizing daily burden.
Cost-Effective
Delivers gait assistance for around ₩2.5 million — a fraction of the cost of a ~₩100 million exoskeleton robot or competing products priced in the tens of millions of won.
Product Composition
A tendon runs from the waist-worn drive unit down to the ankle orthosis, supporting foot clearance during walking.
Clinically Proven
Improvements were confirmed across pathological gait patterns including circumduction, foot drop, and abnormal knee flexion — with increased natural gait, stability, and reduced fatigue leading to higher willingness to wear the device.
