AB  - Introduction: Tactile sensitivity is impaired in older adults, which contributes 
      to the loss of manual dexterity and mobility function. The reliability of 
      classical psychophysical tests, such as two-point gap discrimination, has been 
      questioned. Here we tested a new method to determine tactile acuity during 
      dynamic touch, which is more functional than static touch. The aim was to 
      validate a method providing a high level of discrimination of tactile acuity in 
      the elderly. Methods: We tested the ability of subjects to evaluate the distance 
      between bands printed on poly-methyl-methacrylate (PMMA) sheets. Pairs of sheets 
      were compared in two groups of participants aged from 60 to 74 years; the test 
      group was required to apply a cosmetic foam with an active ingredient on both 
      their hands twice a day for 1 month, the control group had an identical task but 
      used the same cosmetic foam without any active ingredient. The tests were run in 
      a double-blind, placebo-controlled study. Results: The tactile discrimination 
      threshold decreased by 83 mum after 1 month of cosmetic application in the group 
      using the active ingredient, while it was unchanged in the control group. 
      Discussion: The test presented here provided highly accurate results and should 
      be useful to determine tactile performance. It allows the monitoring of tactile 
      rehabilitation and/or skin treatments used to restore tactile acuity in the 
      elderly.
