Objectives: To study the properties (pressing power proportion) and percent agreement an U-thong monofilament and the standard 10 gram nylon monofilament in screening sensation of diabetic patients with feeling numb at their feet.

Study design: A cross - sectional analytical study in U-thong Hospital.

Subjects: Subjects were divided into 3 groups: 3 testers; 15 normal volunteers and 30 diabetic patients who had numbness at their feet.

Methods: There were 3 parts: 1) testing pressing power between the devices (gram) with student’s t-test and ANOVA; 2) analyzing of the feeling differences between the devices in normal volunteers and 3) analyzing of the general and clinical characteristics of the diabetic pantients with mean difference by using the studentís t-test and ANOVA and percent agreement between the devices by using the Chen’s Kappa statistic study.

Results: It was found that there was no difference between the proportion of pressing power of the U-thong monofilament and the monofilament which have 10.0 gram pressing power. The ability of the 15 normal volunteers in distinguishing both of the devices on feet was not different. The percent agreement between the monofilament and the U-thong monofilament at the left and right feet were highly agreed at the significant statistics p < 0.001 (Kappa = 0.84 - 1.00)

Conclusion: A new novel U-thong monofilament is highly agreed with the standard 10-gram nylon monofilament, and it may be used as a substitution in screening diabetic patients with numbness at their feet. Further study on sensitivity and specificity of this tool is recommended.
