Purpose: The radial side of fingers are thought to be the dominant sensory side. With the development of electronic de-vices and lifestyle changes, we think this should be re-evaluated.Methods: We painted fluorescent material on both hands of 26 office workers. Each finger was divided into the ulnar and radial compartment. We analysed how much fluorescent material remained by comparing two pictures, before and after work. Results: On the dominant hand, significantly more fluorescent material remained on the radial side of the ring and little finger compared with the other compartment. On the non-dominant hand, there was no statistical difference between compartments. Conclusion: In this study, the radial sides of the ring and little finger on the dominant hand seem to be less useful in modern life and these compartments can be sensibly less important. This observation can be used as a basic data for re-evaluation of the sensory dominant sides of fingers and it may be helpful in various hand surgery. KCI Citation Count: 0
