Abstract
Objective
To establish normative values for the two-point discrimination test in the Brazilian population.Methods
The present cross-sectional study was conducted in an adult population without neurological conditions affecting the hands. Discrimination was assessed on the fingertip pulp, from the thumb to the little finger, using a graded metal two-point discriminator with fixed tips. Normality was determined using the Von Frey test, with an esthesiometer consisting of calibrated nylon monofilaments.Results
A total of 984 hands, comprising 244 male and 248 female participants, were evaluated. The sample included 354 non-manual workers, 103 manual workers, and 35 retired participants. All fingers showed a discrimination range from 2 to 5 mm. The modes were 4 mm, 3 mm, 3 mm, 4 mm, and 4 mm for the 1 st , 2 nd , 3 rd , 4 th , and 5 th fingers, respectively.Conclusion
All fingers showed a discrimination interval between 2 and 5 mm. The mode was 4 mm for the 1st, 4th, and 5th fingers, and 3 mm for the 2nd and 3rd fingers.
