Bionic Passive Ankle Rehab Trainer
EZAN Yunlv 2.0 patented foldable orthosis with adjustable bidirectional damping & magnetic one-hand lock. Zero power, 300g lightweight design for stroke, post-op & elderly fall prevention, clinical & household dual use.
EZAN Yunlv 2.0 Passive Ankle Rehabilitation Trainer – Patented Bionic Orthosis for Clinical & Home Gait Recovery
Developed from joint lab research between EZAN and Shenzhen Institute of Advanced Technology, CAS, the Yunlv 2.0 ankle rehabilitation trainer breaks the limits of rigid fixed AFOs with 17 independent national patents covering magnetic one-lock buckle, adjustable bidirectional damping and foldable bionic tendon linkage. Rooted in biomechanical papers published on CNKI and international rehabilitation journals, our passive mechanical design eliminates motors, batteries and charging trouble, delivering targeted dorsiflex assistance without electronic faults. Our self-owned 8,000㎡ medical device workshop fully complies with ISO13485 quality control standards, equipped with CNC precision machining, virgin PA composite injection molding and 500,000-cycle fatigue testing lines to guarantee long service life over 3 years. Guided by the brand core idea “Restore Independent Walking Through Accessible Rehabilitation”, we focus on solving core rehabilitation pain points including foot drop, foot inversion/eversion, post-surgical muscle atrophy and elderly fall risks.
Different from low-cost recycled plastic braces on the market, Yunlv 2.0 only weighs ≤300g with aviation lightweight frame, reserving standard 25° dorsiflexion and 35° plantarflexion physiological range of motion. Adjustable bilateral dampers let therapists and users customize auxiliary torque matching mild to severe rehabilitation phases, avoiding joint stiffness caused by full locking. Magnetic snap buckle realizes one-hand donning within 10 seconds, friendly to stroke patients, seniors and users with limited upper limb strength. The whole orthosis fits shoe sizes 34–45 and weight range 40–95kg, reserved space for post-operative ankle edema. Clinical data from tertiary rehab hospitals proves consistent daily use reduces lower limb muscle compensation load by 28% and cuts fall incidents significantly. We provide complete medical registration certificates, bulk clinical training and one-year free replacement straps for global rehab clinics, nursing homes and household patients, balancing professional clinical performance and affordable home rehabilitation costs.
Application Fields & Scenarios
For hemiplegic stroke survivors suffering foot drop and toe dragging, Yunlv 2.0’s bionic linkage lifts instep automatically in swing phase. Adjustable damping lessens tibialis anterior compensation, balances bilateral gait symmetry. It supports daily neighborhood walking and shopping to rebuild outdoor confidence without frequent tripping.
Incomplete spinal cord injury patients lose voluntary ankle control and prone to abnormal foot pronation. Foldable passive trainer maintains neutral foot alignment while retaining joint mobility, progressive damping activates dormant lower-limb muscles for short-distance unassisted walking training at wards.
After ankle fracture or ligament reconstruction surgery, excessive inversion/eversion risks secondary injury. Yunlv 2.0 limits over-deviation with reserved dorsi/plantarflex space, adjustable resistance accelerates muscle recovery without rigid plaster immobilization drawbacks.
Peroneal nerve palsy leads weak foot lifting and unsteady strides. Bidirectional damping delivers targeted auxiliary force to correct supination/pronation deformities. Ultra-light frame allows all-day wear for long-distance community rehab walks and daily commuting.
Elderly users with age-related ankle muscle loss often trip due insufficient toe clearance. The lightweight foldable orthosis provides stable forefoot support during stair climbing and flat walking, effectively lowering household and park fall risks without heavy leg burden.
Rehab clinics adopt Yunlv 2.0 for group gait training thanks to 10-second magnetic quick donning and full-size adjustability. Standardized damping scales unify clinical rehabilitation plans, cutting therapists’ brace adjustment time and boosting daily patient throughput by nearly 40%.
Why Passive Yunlv 2.0 Outperforms Motorized Ankle Exoskeletons
Lots of rehab families hesitate between electric ankle exoskeletons and passive orthoses, and most find EZAN Yunlv 2.0 far more suitable for long-term daily use. Powered devices rely on batteries, Bluetooth and regular software calibration; if the battery dies outdoors, users lose all walking support instantly. Yunlv 2.0 adopts pure mechanical bidirectional damping structure with zero power demand, no charging cables or app setup needed. Its aviation PA frame only hits 300g total weight, much lighter than 1.8kg active ankle exoskeletons like Ruyi series, so seniors can wear it all day without calf soreness. The patented magnetic buckle solves the trouble of multi-layer velcro, which is tough for stroke patients with weak hand grip. Clinical trials from CAS joint lab show passive bionic tendon linkage mimics natural human tendon contraction better than motor-driven pulling, reducing muscle dependency over time instead of replacing muscle function fully. It folds flat into backpacks for hospital visits or travel, while electric exoskeletons take huge storage space. Without circuit failure risks, maintenance cost stays nearly zero, only cheap replacement straps required after years of wear. For home rehab, elderly fall prevention and post-surgery recovery, this power-free trainer balances performance, convenience and budget perfectly.
How Yunlv 2.0’s Adjustable Damping Fix Progressive Rehabilitation Needs
Most single-spring ankle braces supply fixed rigid force that cannot match patients’ changing muscle strength during recovery, either too stiff in early rehab or too weak after partial healing. EZAN Yunlv 2.0 innovates bilateral adjustable dampers with rotary knobs on both sides, letting users independently tune dorsiflex assist torque as their ankle function improves. In post-surgery early stage, therapists turn down damping to offer gentle auxiliary support without stretching fragile healing tissues. When patients regain partial muscle control after 4–6 weeks, higher damping can be switched for longer outdoor walking training. The bionic frame retains full 25°/35° ankle motion range rather than locking joints, which stops disuse muscle atrophy that commonly appears with solid AFOs. Thousands of rehab ward records prove patients using variable-damping orthoses recover full ankle mobility 14 days faster than those with fixed spring braces. The damping knob has clear numerical scales, so family caregivers can follow printed rehab guides to adjust parameters without professional therapist present. All damping components pass 100,000-cycle wear testing, keeping stable auxiliary force for over two years of daily high-frequency use. It works for stroke, spinal injury, ankle operation and aged mobility loss, covering the whole rehabilitation cycle from bed rest recovery to independent outdoor walking.
Magnetic One-Hand Buckle – Core Patent Solving Wearing Barriers for Weak-Limb Users
Traditional multi-strap ankle orthoses take 2–3 minutes to fasten, creating huge mental stress for patients with stroke, nerve damage or arthritis whose hands lack grip strength. Many seniors give up daily rehab training simply because they cannot manage complicated velcro layers alone. EZAN obtained independent national patent for Yunlv 2.0’s magnetic quick lock system, cutting full donning time down to under 10 seconds. Users only align two magnetic terminals and press lightly to lock tight; a slight side pull releases the whole frame without hard tearing. R&D team calibrated magnetic force through 18-month repeated testing, strong enough to stay locked during stair climbing and brisk walking yet easy to detach with weak finger power. All magnetic modules are fully sealed and sweat-proof, adsorption power won’t fade after long-term contact with sweat or light rain. Rehab therapists report training frequency rises over 60% after patients switch to Yunlv 2.0, as the simplified wearing process removes daily resistance to regular practice. Replacement magnetic buckles cost little if wear occurs after heavy daily use, and our customer service sends installation video tutorials free of charge. Unlike cheap market magnetic braces that pop off randomly while walking, our balanced magnetic tension avoids accidental disconnection without requiring powerful hands to unlock, perfectly fitting hemiplegic, nerve-injured and elderly rehab users with limited upper-limb mobility.
Aviation Virgin PA Material Eliminates Compression Soreness for All-Day Wear
Most budget ankle orthoses adopt recycled brittle plastic that develops sharp edges after one month of bending, causing blisters and red pressure marks on calves and insteps during long walks. EZAN Yunlv 2.0 selects brand-new aviation-grade virgin PA composite via integrated injection molding, balancing lightweight property and high mechanical toughness. The whole frame only weighs ≤300g, 40% lighter than standard solid plastic AFOs, so users can wear it from morning grocery shopping to evening park strolls without leg fatigue. Every frame radian is optimized with 10,000+ human body scanning data, distributing pressure evenly across soft tissue instead of concentrating force on narrow contact points. Matching antibacterial breathable elastic straps inhibit bacterial reproduction from accumulated sweat, solving itch and odor problems plaguing cheap fabric bands. The PA material passes IP54 wear and dust resistance testing, resisting abrasion from daily shoe friction and minor outdoor gravel impact. Unlike metal alloy frames that feel cold in winter, PA maintains mild surface temperature without skin irritation for sensitive elderly skin.
Foldable Compact Design Makes Rehab Accessible for Travel & Small Apartments
Bulky rigid ankle orthoses occupy large storage space, bringing huge trouble to users living in small apartments or needing frequent hospital visits and short trips. EZAN Yunlv 2.0’s dual-hinge foldable structure flattens the whole trainer smaller than a standard shoe box, easy to slip into backpacks, handbags or closet drawers without extra storage cabinets. Unlike electric ankle assist devices that need separate charging adapters and storage bags, this passive trainer requires no extra accessories, just fold and carry directly. Many stroke patients need regular rehab check-ups at hospitals; the compact fold design lets them bring the orthosis along for on-site gait assessment without carrying large equipment bags. Nursing home caregivers praise the centralized storage advantage: dozens of Yunlv trainers stack neatly in one locker after daily training, saving valuable ward cabinet space. During family travel or outdoor rehab hiking, users can fold it and take it to maintain consistent daily training instead of pausing recovery routines. The folding hinges use silent self-lubricating bearings, no creaky friction noise when unfolding and folding repeatedly over thousands of times.
ISO13485 Full Production Chain Ensures Consistent Medical-Grade Quality
Many small-scale ankle brace manufacturers outsource molding and assembly processes, leading unstable product quality and inconsistent auxiliary force between batches, which seriously interferes standardized clinical rehabilitation plans. EZAN operates a self-owned 8,000㎡ medical device production base with full independent production lines covering raw material inspection, CNC machining, injection molding, component assembly and finished product fatigue testing, fully following ISO13485 medical quality management system. Every Yunlv 2.0 trainer undergoes three layers of inspection before delivery: material biocompatibility test, 500,000-cycle bending fatigue test and dynamic damping force calibration.
We hold complete Class II medical device registration certificates and international CE compliance files, fully satisfying hospital public bidding and export customs clearance requirements. Our in-house R&D lab cooperates with SIAT CAS to conduct biomechanical simulation for every structural upgrade, ensuring every parameter matches clinical gait data from tertiary rehab hospitals. Mass bulk orders from rehab centers include free one-on-one therapist operation training, teaching staff to adjust damping and magnetic buckles correctly for different patient disorders.
Bionic Tendon Linkage Reduces Muscle Compensation & Fall Risks
Most simple spring ankle braces only provide upward forefoot lift without simulating natural tendon cycle, forcing hip and knee joints to generate extra compensatory force and raising fall risks during long walks. EZAN R&D team referenced dozens of CNKI biomechanics papers and international orthotic journals to design Yunlv 2.0’s patented bionic Achilles tendon linkage structure, perfectly replicating human tendon stretch and retraction rhythm through a full gait cycle. During swing phase, elastic linkage pulls the instep upward to clear the ground; on heel strike, the mechanical structure automatically releases tension to allow free plantarflexion, matching physiological walking mechanics instead of rigid constant support.
Independent lab gait analysis proves this balanced force distribution cuts hip and knee compensatory load by 27%, lowering fatigue after 1km continuous walking significantly. Adjustable bilateral dampers control auxiliary torque progressively to train patients’ own ankle muscles rather than fully replacing muscle output long-term, preventing irreversible disuse atrophy seen with fully locked AFOs. Clinical follow-up of 200 stroke and spinal injury users over six months records 66% fewer accidental falls compared to patients wearing single-spring orthoses. The silent hinged linkage avoids distracting noise during rehab training, and smooth curved frame surfaces prevent pressure sores on calf soft tissue even for all-day continuous wear, combining biomechanical safety and long-term training comfort for neurological and orthopedic rehab patients.
