Distribución de presiones muñón-prótesis y temperatura superficial del muñon en amputados transtibiales

Zusammenfassung

This study aims to analyze the distribution of the pressures exerted by the transtibial amputee stump inside the prosthetic socket and see if there is any correlation with increasing surface temperature itself. The same is intended to design a study protocol for the analysis of the relationship between these variables that influence the comfort and quality of life of patients amputees. We evaluated five patients of mean age 35 who had amputees at least 10 years, with an average weight of 85 kg and height of 1.77 m. To study the pressure distribution, the system has been used was K-Scan of TEKSCAN and for temperature a thermal camera FLIR brand, model T360. We can’t found relationship between the pressure points and the values of temperature gradient. No relationship exists between the distribution of ΔT (temperature increase) on the stump produced after the march and the pressure distribution measured during the same. Therefore it seems that the level of pressures between the stump and the prosthesis isn’t causing the observed ΔT in the stumps of transtibial amputees
