Pedi PHAT

The only carbon energy storing AFO.

Strength:

The diagnostic/prefabricated orthosis are made in two strengths, Firm and Moderate. A firm core spring will produce 25-40 pounds of resistance force between 10-15 degrees of flexion. A moderate core structure produces 15-25 pounds of resistance. This range of measure is based on the normal range of motion in gait. At a neutral standing position the core structure is slightly flexed, producing a small force for standing stability. During gait, the ankle progresses into 10 degrees of dorsi-flexion before the moment of heel off. At that point plantar flexion occurs for propulsion. The core structure is designed to produce a quickly increasing resistance. This resistance will load up over these 10 degrees of motion to give the desired propulsion force to replace the deficit calf function.

Step 1: Size Selection:

The brace height should be as high on the back of the lower leg as possible. The length of the lever arm of this part of the brace is key for the braces to function properly. In a sitting position, with the knee bent at 90 degrees. Measure the distance from the hamstrings (bottom of the thigh, just behind the knee) to the bottom of the heel (or the floor, just behind the heel). The height of the brace should be less then the height of the leg measurement. The brace is able to be cut down up to 1/4 inch, if necessary.

The length of the foot section is measured from the back of the heel to the ball of the foot (not to the end of the toes). The measurement of the patient should not be more than 1/4 inch shorter or 1/2 inch longer than the length of the brace. Padding can be added if it will help to stay within these perimeters.

If the prefabricated brace is not able to fit properly, it will not function properly for the patient.

Select the most appropriate size based on the instructions above

Step 2: Strength selection:

Evaluate the strength of each leg separately. Have the patient stand on one leg, the one you are testing. Stabilize the patient as necessary. Ask the patient to raise the heel off the ground, going up on to their toes and hold.... If the patient is not able to raise the heel off the floor or is only able to raise the heel a small bit off the floor. They would need a firm spring to match their strength deficit. If the patient is able to raise more than half way or all the way but not able to hold position. They would need a moderate strength to match their deficit.

In cases of trying to control knee positioning ( hyper-extension, crouch gait, toe walking) a firm spring is recommended. In these cases the patient may have full strength (able to go up on their toes and hold position) during testing. In these cases, the firm strength of the spring is not replacing calf strength it is resisting it. As such a stronger strength is needed.

Select the most appropriate strength based on the instructions above

Step 3: Brace selection:

In selection of a single (unilateral) right or left brace make sure the right selection is noted. In cases of both (bilateral) right and left braces it is found to be better for both braces to be of the same strength. Usually going to the firmer strength. This commonly provides a better overall symmetry in gait (walking).
