Abstract

The effects of high heeled shoes on pedal pressure in normal women : The a uthors stud ied the effects of high heels in ten normal female individuals, on four different conditions: barefoot (S0), S1 (3.0 cm), S2 (6.0 cm), and S3 (9.6 cm), 400 steps, as to the distribution of the maximum peak pressure, vertical impulse, time analysis of the step, speed and location of the centre of pressure (COP), using the F-Scan, (Teksca n, Boston, MA) baropodometre. Special shoes, with identical form and materials, were manufactured to th is purpose. The results showed that the maximum peak pressure is reduced by means of using shoes. The isolated analysis of pressure levels on the foot soles does not constitute a safe method for the determination of the "foot at risk" condition. Using high heels the maximum peak pressure showed a concentration increment under the hálux and under head of the first metatarsal, augmenting significantly the total step time, especially due to the overload of the midfoot, while an underload of the rearfoot, with no change in the forefoot was observed. The use of high heel shoes determined an increment of the vertical impulse. By elevating the heels, the COP is showed at the midfoot, accompanied by a faster COP at the rearfoot. The speed of the COP at the forefoot was constant, regardless of the heel heig ht. The increment of the heel height caused a "centralization" and "retification" of the trajectory of the COP.
