A New Saddle Pad for the JAS Ankle
Our new saddle pad design is anatomically shaped and has more surface area to improve patient tolerance and comfort in the JAS ankle devices.
The ankle joint acts as a hinge between the long lever arm of the leg and the weight-bearing surface of the foot. Our body weight is poised over the ankle, and movements such as running, jumping, and twisting may transmit abnormal forces along the ankle joint.
The ankle is one of the most frequently injured joints in the body.
Treatment commonly consists of a period of immobilization, followed by physical therapy for range of motion, stretching, and strength building.
New Saddle Pad design.
JAS Ankle Devices are Effective for: Fractures, Achilles Tendon Rupture/Repair, Burns, Neurological Conditions, and Plantar Fasciitis.
At JAS, we continuously review feedback from clinicians and patients on ways to improve patient outcomes. Most recently, we made a modification to our JAS Ankle device to improve patient tolerance and comfort during use by replacing our butterfly pad with a saddle pad. Let us explain:
To effectively stretch the powerful Achilles tendon, the JAS device utilizes a 3-point force system consisting of:
A proximal lever arm extending to the posterior proximal calf.
A distal lever arm extending to the plantar surface of the metatarsal heads of the foot.
A counterforce for the two lever arms over the dorsal/anterior aspect of the ankle.
This centralized counterforce is critical to the effectiveness of the 3-point system in creating a therapeutic stretch load. The pressure applied by the counterforce can be significant when the proximal and distal lever arms are working against extreme tendon tightness or contracture.
This counterforce in the JAS ankle devices is created by a strap that runs diagonally from the center of the heel across the anterior/dorsal aspect of the ankle.
To distribute this critical counterforce over more skin surface area across the ankle, thus reducing the pressure concentration, we have developed the JAS Saddle Pad to replace our butterfly pad. This new design is anatomically shaped and has more surface area to improve patient tolerance and comfort in the JAS ankle devices.
