  "abstract": "Objective\n\nTo establish normative values for the two-point discrimination test in the Brazilian population.Methods\n\nThe 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\n\nA 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\n\nAll 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.",
