Pressure redistribution by molded inserts in diabetic footwear: a pilot study

J Rehabil Res Dev. 1994 Aug;31(3):214-21.


A small-scale trial is described to demonstrate and evaluate the redistribution of plantar pressure resulting from the use of custom-molded inserts in the orthopedic shoes of diabetic patients at risk of plantar ulceration. A pressure-measuring insole based on force-sensitive resistor technology enabled the load distribution to be compared using molded inserts and flat inserts fitted into the same shoes. An analysis of the 12 peaks of pressure that could be identified under a discrete metatarsal head of six subjects in the trial showed that the pressure was significantly reduced with the use of molded inserts (flat inserts: 305 +/- 79 kPa; molded inserts: 216 +/- 70 kPa; n = 6 p < 0.005). Technical limitations of the equipment and the difficult choice of match of flat insert to molded for comparison suggest that further studies are required for a definitive result.
