Description

A polypropylene ground reaction ankle-foot orthosis (GRAFO) is a type of orthotic device used to support and stabilize the foot and ankle during walking or standing activities. The design you described includes a ventral shell that extends up to the mid-patella, and the GRAFO is worn with shoes to ensure proper alignment while standing.

Polypropylene is a commonly used material in the fabrication of orthotic devices due to its lightweight, durable, and flexible properties. The use of polypropylene allows the GRAFO to provide support and control while still allowing some degree of natural movement.

The ventral shell refers to the lower portion of the GRAFO that wraps around the foot and ankle. It is typically custom-made to fit the individual’s foot and ankle anatomy and extends up to the mid-patella, which is the middle portion of the kneecap. This design provides additional support to the ankle, foot, and lower leg, and helps to stabilize the knee joint.

When wearing the GRAFO with shoes, it is essential to ensure proper alignment. Correct alignment helps distribute forces evenly and promotes optimal biomechanics during standing and walking. A trained orthotist or healthcare professional will assess and adjust the GRAFO and shoe combination to ensure that the individual’s feet are properly positioned within the shoes, and the GRAFO provides the necessary support and alignment.

It’s important to note that the specific design and fitting of a GRAFO can vary based on an individual’s needs and the recommendations of their healthcare provider. Therefore, it is best to consult with a healthcare professional or orthotist who can evaluate your specific requirements and create a GRAFO that is tailored to your unique needs.
