WalkOn Carbon Ankle Foot Orthosis (AFO) Analysis Report

Device Identification

The product examined in the images is a dynamic ankle foot orthosis (AFO) made from carbon fiber material, used in the field of medical orthopedics. The device consists of a vertical support strut extending from the rear to the calf, a padded strap encircling the calf, and a footplate positioned under the foot.

Brand and Model Identification

As a result of detailed examination of the images, the device’s model information has been definitively identified.

• Model: The word WalkOn is clearly legible on the textile strap encircling the calf area of the device in the image. This word definitively indicates the product’s model.

Authenticity Assessment

The product’s general design lines, the characteristic texture of the carbon fiber material used (square patterned structure), the font of the “WalkOn” print, and the craftsmanship of the joining points support the assertion that the product is an original medical item. No low-quality plastic components or blurry prints, suggestive of contract manufacturing or counterfeit products, were observed in the images.

Areas of Use

This device is designed to improve the walking ability of patients experiencing “Drop Foot” syndrome. Its use is common for the following conditions:

• Drop foot conditions resulting from peroneal nerve palsy.
• Gait disorders developed after stroke.
• Neurological disorders such as traumatic brain injury or Multiple Sclerosis (MS).
• To prevent the toes from catching on the ground during walking by maintaining the foot at a 90-degree angle and to achieve a more natural gait by providing energy return.

Quantity Information

In the wide-angle analysis of the first image, a total of 2 units of carbon AFO (orthosis) devices were identified in the room. One of these is being held by a person, and the other is resting on the parquet floor in the background.

General Condition and State

The product is visually in a used condition. It is not “New” or “Unused”. It is in second-hand condition, but its structural integrity has been preserved.

Physical Deformation and Wear Analysis

• Footbed Liner: On the beige-colored liner/insole part of the device that comes into contact with the foot, there are noticeable dirt, darkening, and friction marks resulting from use. This part is the clearest indicator that the device has been used for some time.
• Textile Parts: Fraying, dust, and small textile fibers have been observed on the black pad providing calf support and the hook-and-loop strap. The fabric surface has lost its factory sheen.
• Carbon Body: No deep cracks, fractures, or separations visible in the photographs have been detected in the carbon fiber structure (main body strut). Its structural form appears sound.

Material and Mechanical Components

The main frame of the device is made from carbon fiber composite material, providing high durability and lightness. There is no mechanical hinge system; its flexibility comes from the dynamic nature of the material itself. The rear support strut and footplate have a unibody (one-piece) design.

Accessories and Fasteners

The following accessories and components are present on the device:

• Calf Strap (Cuff): A textile part with the model name written on it and a hook-and-loop mechanism is present, which secures the device to the user’s leg.
• Inner Pads: Black sponge/textile-supported cushions are present, softening contact with the skin.
• Other Items: Black leather shoes, potentially compatible with the device, are visible in the background of the images, but these are external clothing items, not direct parts of the orthosis. The device’s own box, user manual, or spare hook-and-loop fasteners are not present in the images.

Battery and Electronic Components

This product has an entirely mechanical/passive dynamic structure. It does not contain any electronic components, motors, sensors, or batteries.

Size and Compatibility

No clear label regarding the product’s size (S, M, L, etc.) or orientation (Right/Left) is legible in the images. However, its structure suggests it is a standard orthosis size designed for adult use. The fact that the shoes used (in the background) are adult male shoe sizes confirms that the product belongs to an adult individual.

Potential Failure Risk

The carbon fiber body of the device appears sturdy. No serious risk of breakage was perceived from the visual inspection. However, for hygienic reasons, the footbed liners and textile pads that contact the skin may need to be replaced or thoroughly cleaned. In prolonged use, the grip performance of the hook-and-loop straps may decrease, which could necessitate a potential replacement.
