What technique uses an inked grid and bladder to reflect pressure areas on the foot?

The technique that uses an inked grid and bladder to reflect pressure areas on the foot is known as a Pedograph. This method involves the use of an inked surface that records the pressure distribution when a foot is placed onto it. As the foot compresses the bladder, the ink transfers to the foot, creating a pattern that visualizes pressure points and the overall footprint. It is particularly useful for identifying areas of high pressure that may be prone to calluses, blisters, or ulcers, which is critical in therapeutic shoe fitting for individuals with diabetes or other foot conditions.

Utilizing this technique helps shoe fitters customize footwear to alleviate pressure in specific areas, thereby enhancing comfort and preventing injuries. Understanding the pressure distribution is essential for proper fitting and designing therapeutic footwear.
