Gait rehabilitation exoskeleton is a clinical-grade wearable lower limb robotic device specially developed for walking function recovery of hemiplegia, spinal injury, lower limb orthopedic surgery and mobility-impaired elderly patients. Integrated with multi-dimensional real-time motion sensing modules and programmable adaptive servo drive system, this gait rehabilitation exoskeleton guides hip, knee and ankle joints to complete standard bionic gait cycles, collects walking posture data in real time and adjusts graded auxiliary torque according to individual recovery levels to correct abnormal gait trajectories and rebuild normal walking muscle memory. It supports multiple training modes including static standing training, flat ground walking practice and gentle slope gait exercise, effectively activating atrophied leg muscles, accelerating lower limb blood circulation and improving body balance and coordination ability. The lightweight medical composite frame meets IP54 dustproof and splash-proof standards, suitable for hospital rehabilitation departments, professional rehabilitation centers and household long-term recovery training. Widened soft padded adjustable binding straps fit patients of different heights and leg circumferences, equipped with swappable long-life lithium batteries to support all-day continuous rehabilitation training. Humanized flexible joint structure retains full natural limb movement range, matched with intuitive one-key mode switching and simple operation panel for therapists, patients and caregivers to use conveniently. Built-in anti-fall early warning, overload automatic lock and emergency stop triple safety mechanisms fully avoid secondary injuries during repeated training. This professional gait rehabilitation exoskeleton achieves high-precision human-machine motion synchronization, shortens overall rehabilitation cycles and helps patients gradually recover independent and stable walking ability.
