Background and Aim: Tactile localization (TL) is one of the standard assessments to be performed under combined cortical sensory assessment. TL is the ability to locate the point of sensory contact and surprisingly, till date there is no normal reference available for estimating TL. Hence, there is a need to calculate the normative reference of TL among school-going children aged between 8 and 13 years. Materials and Methods: A total of 365 healthy school-going children aged between 8 and 13 years were included in this cross-sectional observational study. Children with any neurological condition and other conditions, which prevent them from taking part in the study were excluded. The sample was recruited by stratified random sampling method from the recognized schools in Ambala district, Haryana, India. After the anthropometric measurements, TL acuity was established by point-to-point tactile localization (PPTL) technique. In this technique, the children were asked to relocate the point of contact made by the investigator over identified 15 areas, and after that the distance between the point of contact made by the principal investigator and the relocation point made by the children is measured in centimeters (cm). The mean of three readings were used to estimate TL acuity. Result: TL acuity ranges from 0.9 (0.5, 1.5) cm in little finger of palm to 1.5 (1.0, 2.5) cm in middle of posterior arm. TL acuity increases with increasing age. There exist no significant (P ≥ 0.05) difference in the normative reference value between male and female among the identified 15 areas. Conclusion: Normative reference values of TL acuity have been established among school-going children between 8 and 13 years.
