Background: Tactile acuity is often altered in various persistent pain conditions. There are limitations to some of the current tactile acuity measures available for clinical use.

Objectives: Develop and test reliability of a novel grid localization test (GLT) for tactile spatial localization. Establish inter-rater reliability along with minimal detectable difference for GLT and compare to more established tactile acuity testing of two-point discrimination.

Design: Cross-sectional, observational study of inter-rater reliability.

Methods: Two different testers measured tactile spatial localization testing for the low back utilizing newly established GLT procedure on healthy individuals. Participants during GLT had to identify which area of the back was touched within a defined grid based on 10 touches. An accuracy score was determined based on correct/incorrect response.

Results: Thirty-six participants (N = 36, female = 27) with an average age of 23.3 (range 22 - 30) were studied. ICC (2, k) for the grid localization test between testers was 0.74. The average score was 78% correct with a minimal detectable difference of 29%. There was no correlation between GLT results and two-point discrimination.

Conclusion: The novel GLT demonstrated fair inter-rater reliability and may be evaluating a different component of tactile acuity compared to two-point discrimination testing.
