Top 100 Biomechanical Guidelines #33: Hannaford Orthotics should be Refurbished every 3 to 6 months
I love to cover Hannaford Orthotic Devices with leather initially to see the wear patterns, especially correlating the wear patterns to what I see in gait, and comparing right to the left sides. The wear patterns may reveal that the foot needs more padding in certain areas, or where there is more need for pronation or supination support.
With the Hannaford Orthotic Device, 30% of the bulk is reduced over the first month as the memory foam molds to the foot. Around 3 or 4 months into wearing the devices, medial and lateral buttresses are applied to the bottom to improve the pronation/supination stability dramatically. I use 1/8 inch grinding rubber for this purpose. (see the post on grinding lifts for ordering of this material).
I also change the thinner leather with thicker 1/8 neolon/spenco for better shock absorption while refurbishing.
Normally, when using the Hannaford device, a new one is ordered at 3 to 6 months. In this way, the patient can have adjustments made on both pairs at any office visit, and can alternate between the two pairs which saves the life of each pair dramatically. By alternating, when one pair begins to be less supportive, or more painful, or both, compared to the other pair, you will know when it is time to have it refurbished.
