A.C.T. Impression Stand Instructions

 The A.C.T.™ Impression Stand is uniquely designed to simplify the molding process utilizing the A.C.T.™ pillows. Once the subtalar joint has been aligned, the knee cups hold the patient in position for hands free molding/casting. The plumb bobs identify the alignment of the knee over the metatarsals providing both a reference point and diagnostic tool.

Step 1:Have the patient step onto the pillows taking care to locate the feet in the appropriate position with the ball of the foot at the transition and the heel centered in the back.
Step 2: Loosen the knobs on the sides of the cross bar and position the bar slightly below the plane of the knees.
Step 3: Loosen the knee cup knobs and center the cups to the patient’s knees and retighten. Have the patient bend the knees so they fit securely into the knee cups. Grasp the subtalar joint with one hand and the knee cup knob with the other.

Loosen the knob and slide the knee cup medially and laterally while feeling for subtalar alignment. Once alignment is achieved tighten the knee cup knob. Repeat for the other foot.

Step 4: Suspend the plumb bobs and check alignment. The plumb bob should locate between the first and third toes, normally over the second. A lack of symmetry may suggest that subtalar alignment should be rechecked or that perhaps there is a leg length discrepancy or other anomaly that needs to be explored.

Step 5:  Place molding/casting medium under one foot at a time and allow to cool/cure. Repeat for the other foot.
