GRAFO stands for Ground Reaction Ankle Foot Orthoses. The purpose of a GRAFO is to provide mechanically-induced stability to the lower limb. It is characterised by its design, where it aims to maintain the ground reaction force anterior to the knee joint centre, which prevents knee instability and collapse for a patient with quads and/or ...

A ground-reaction AFO (GRAFO) is essentially the same as a rigid AFO. The difference is that an anterior shell is attached, which will spread the load that is applied as part of the Three-Point Pressure System to the front of the shin.

2018年8月26日 · Both SAFO and GRAFO are specific types of ankle–foot orthoses (AFOs). Functionally, SAFO and GRAFO are similar in that they both apply a corrective internal plantarflexion moment to the ankle in response to ankle dorsiflexion.

The GRAFO is a solid orthosis that acts as a strut between the ankle and knee, leveraging the large tibia to improve knee control during the stance phase of walking. Directing the ground reaction force to create an extension moment at the knee, it …

A Ground (Floor) Reaction Ankle Foot Orthosis (GRAFO or FRAFO) is a type of custom fabricated, molded plastic, AFO capable of triplanar control of the foot/ankle complex. Generally formed from polypropylene, there are several variations on the GRAFO but all include an anterior shell which captures the tibia proximally.

Aim: To investigate any performance differences between the solid ankle-foot orthosis (SAFO) and ground reaction ankle-foot orthosis (GRAFO) designs for correcting crouch gait in children diagnosed with cerebral palsy (CP).

The ground reaction AFO (GRAFO) is a specific type of AFO that is designed to harness the ground reaction moment around the ankle to increase the stability of the knee in stance. 14,15 The GRAFO has been used most frequently in children with spina bifida and cerebral palsy. The GRAFO has a solid pretibial shell, as opposed to the pretibial ...

A GRAFO is used to control instabilities in the lower limb by maintaining proper alignment of limbs and controlling their motion. It reaches around to the front of the knee extending down to the ankle. It works by altering a patient’s limb presentation to displace load and impact as well as offering further control to the knee.
