An orthotic insert supports the arch and foot inside the shoe, while an ankle brace stabilizes the ankle joint itself. In some cases, patients benefit from both.
Foot, ankle, and knee pain affect millions of people across New York City every day—whether from arthritis, sports injuries, neurological conditions, or long hours spent walking the city streets. At Gramercy Custom Orthotics & AFO, Dr. Shenker and our clinical team specialize in designing and fitting custom Ankle Foot Orthoses (AFO), alongside precision ankle and knee braces. By utilizing advanced gait analysis and 3D casting, we provide real relief and restore mobility. Unlike generic, store-bought supports, our orthotics are precision-engineered to your unique biomechanics, ensuring long-term comfort and clinical effectiveness.




At Gramercy Custom Orthotics & AFO, we provide a full spectrum of bracing services in NYC:
Designed for patients with foot drop, neurological conditions, or post-stroke recovery.
Supports dorsiflexion and prevents tripping.
Encourages a safer, more natural gait.
Lightweight designs that fit inside everyday shoes.
Ideal for chronic ankle sprains, arthritis, and ligament injuries.
Provides stability during walking and sports.
Reduces swelling and pressure on the ankle joint.
Prevents re-injury in active patients.
Perfect for arthritis, ligament tears (ACL/MCL), or post-operative recovery.
Offloads pressure on painful areas.
Restores stability and confidence.
Tailored for both active and daily lifestyles.
Each brace is created based on a comprehensive evaluation and custom fabrication process that ensures accuracy and durability.





Customer Choice
Generic braces you find online or in a drugstore are designed for the “average” body. But no two patients are alike, and your biomechanics are unique. A custom brace accounts for:
Your exact anatomy: Advanced 3D casting and scanning ensure a precise, frictionless fit for your foot, ankle, or knee.
Your specific diagnosis: Bracing for osteoarthritis requires different structural support than braces designed for sports injuries, foot drop, or neurological conditions.
Your daily lifestyle: An active runner, a construction worker, and an office professional all require varying levels of flexibility, weight, and durability.
Your long-term health: Properly fitted custom orthotics correct your gait, preventing further joint strain, accidental falls, and secondary injuries.
Choosing custom means you get medical-grade, physical therapy-aligned support built specifically for you – not a generic compromise.

A Microprocessor KAFO (MP-KAFO)—also known as a powered or active Knee-Ankle-Foot Orthosis — is one of the most advanced forms of lower-limb bracing available today. Unlike traditional locked or mechanical KAFOs, microprocessor-controlled systems use real-time sensors, onboard electronics, and intelligent control algorithms to dynamically stabilize the knee and support the ankle during walking and standing.
At Gramercy Custom Orthotics & AFO in Manhattan, Microprocessor KAFOs are prescribed for patients with complex knee instability, neuromuscular weakness, and high fall risk who require a level of support that conventional bracing simply cannot provide.
A Microprocessor KAFO is a battery-powered orthotic system that spans the thigh, knee, ankle, and foot, integrating mechanical support with advanced electronic control.
Key components include:
Rigid or semi-rigid thigh and calf shells: Custom-molded for a secure, comfortable fit that transfers weight safely.
A microprocessor-controlled knee joint: The “brain” of the brace that adjusts resistance on the fly.
An articulated ankle joint with a footplate: Designed to promote a natural heel-to-toe walking motion.
Embedded real-time sensors: These analyze your gait mechanics hundreds of times per second.
The microprocessor continuously interprets movement data—such as limb position, loading response, and walking speed—and automatically adjusts knee stability during each phase of your gait. This allows the knee to remain fully stable while bearing weight, while permitting natural, controlled knee flexion as you swing your leg forward.
Microprocessor KAFOs are typically prescribed for patients with combined knee and ankle instability whose mobility cannot be adequately managed with a standard AFO or traditional KAFO.
Common indications include:
Severe quadriceps weakness
Post-polio syndrome
Incomplete spinal cord injuries
Stroke recovery (specifically targeting knee instability and foot drop)
Multiple Sclerosis (MS)
Neuromuscular disorders affecting stance-phase control
Recurrent knee buckling associated with a high fall risk
These devices are particularly valuable for patients who require rigid stance-phase knee control but wish to regain a smoother, safer, and more functional walking experience.



Intelligent Knee Stability: The electronic knee unit can lock, unlock, or modulate resistance automatically. This provides stance-phase security without forcing the knee to remain rigidly locked throughout your entire gait.
Active or Semi-Active Assistance: Depending on the specific system, the device dynamically adapts to:
Assist knee extension during stance.
Control knee flexion at initial ground contact.
Significantly reduce sudden knee buckling and instability.
Dynamic Ankle Support: Unlike solid AFOs, MP-KAFOs typically feature an articulated ankle joint, directly improving toe clearance, natural rollover mechanics, and overall gait symmetry and efficiency.
Lightweight Advanced Materials: Modern Microprocessor KAFOs utilize carbon composite frames or 3D-printed structural elements, ensuring maximum strength and durability at a reduced weight.
Battery-Powered & Programmable: Powered by rechargeable batteries and equipped with wireless programming, these devices allow for precise, on-the-fly customization based on the patient’s real-time gait and functional goals.
A Microprocessor KAFO is never an off-the-shelf device. Successful mobility outcomes require a highly clinical, customized approach. The process includes:
Comprehensive biomechanical and gait evaluation.
Custom fabrication of the thigh, calf, and foot components.
Precise alignment of both the knee and ankle joints.
Proprietary software programming tailored exclusively to your movement patterns.
Structured gait training and ongoing follow-up adjustments.
At Gramercy Physical Therapy, your Microprocessor KAFO fitting is performed within a comprehensive rehabilitation model. We seamlessly integrate expert orthotic fabrication with dedicated physical therapy to ensure your safety, comfort, and long-term success.



When you visit our NYC clinic, we ensure a highly clinical, hands-on approach that generic online vendors simply cannot match. Here is what you can expect:
Comprehensive Evaluation: Our clinicians assess your movement, posture, pain patterns, and daily activity needs through advanced gait analysis.
Precise 3D Scanning: We take exact molds or digital scans of your foot, ankle, or knee to guarantee a perfect anatomical match.
Custom Fabrication: Your brace is meticulously crafted from high-quality, medical-grade materials designed for both durability and comfort.
Expert Fitting: We ensure your brace feels right, moves naturally with your body’s biomechanics, and causes zero irritation.
Ongoing Follow-Up Care: As your condition improves or changes over time, we fine-tune your brace to maintain the optimal level of support.
