[WEB SITE] SureStep: A Revolutionary Bracing Concept

AFO Mechanics

surestep-2SureStep manufactures a variety of products but is primarily known for the SMO (Supra malleolar orthosis) and pediatric AFOs (ankle foot orthosis). The SureStep SMO is meant for patients up to 80 pounds with hypotonic presentations. The purpose is to control the side to side movements of the ankle. The trim lines can be extended longer laterally or medially depending on whether the patient is pronating or supinating. As patients grow older there is a device called the Big Shot that accommodate children and adults weighing over 80 pounds. What makes the SureStep SMO so unique is the dynamic function that the brace allows. It uses compression to create alignment, unique trim-lines to allow freedom of motion where needed, and made from a material that travels together along with the foot.

Controling the Tri-Planar Deformities

This works under compression to maintain stability through midline. In young patients with CMT they can possibly present with a more over pronated foot position because of the low muscle tone (hypotonia) prior to developing a high arch foot presentation. This can been seen in CMT patients who have some symptoms of the disease but have not developed a high arch otherwise known as pes cavus foot. The SMO holds the heel in vertical alignment, giving stability in a coronal plane (side to side) position. An SMO is not necessarily for a patient who has weaknesses pushing up or down the ankle, just poor side-to-side movement.

Improving Stability During Gait

The device is designed to allow for motion to still occur from in and out of the midline position but limits the extremes that the foot would go to, in other words the extreme rolling inward our outward of the ankle. The goal is to improve balance and stability, or limit orthopedic injury. This helps limit out toeing or in toeing as well by improving the position to foot is landing on the ground. Having improved alignment may also utilize remaining strength for dorsiflexion or plantarflexion because the line of pull that these muscles are in has improved line of progression.

Fitting the Device

The trim-lines of the SureStep SMO are designed to be either longer on the lateral border for pronation or medial border for patient who supinate excessively and the orthotist should make the appropriate selection based on the patient’s mechanics. These trim-lines are critical to the successful outcome of this device. Although the SureStep SMO is primarily designed for a younger population as children get older or adults who still have need for such a device the same mechanism of function can be accomplished using the BigShot SMO manufactured by SureStep.
