ABSTRACT
Objective:
The aim of this study is to evaluate whether Semmes-Weinstein monofilaments could be used to reliably assess the sensitivities of different abdominal wall regions.
Methods:
Semmes-Weinstein monofilaments were used to evaluate skin sensitivity to abdominal pressure in 20 volunteers. The abdominal skin was divided into nine regions. The assessment of skin sensitivity to pressure was carried out three times in each area, with 1 week intervals between measurements.
Results:
No significant differences in the pressure threshold were observed when the three measurements in each region were analyzed separately. However, with the Semmes-Weinstein monofilament technique, a statistically significant difference was observed between the values of pressure obtained in each abdominal region.
Conclusions:
SemmesWeinstein monofilaments are a reliable tool in evaluating abdominal skin sensitivity to pressure. A statistically significant difference was observed between the different areas of the abdominal region with this technique. With the method reported in this study, it was possible to establish a protocol to reduce subjectivity and measure the skin sensitivity to pressure.
