| Outline of Final Research Achievements |
This study aims to determine the effect on tactile perception of the forearm and fingertip and Braille reading by applying Menthol to the forearm in persons with diabetes-induced visual impairment. Before the experiment, we applied topical Menthol to the forearm of healthy persons and it was confirmed that tactile perception of the ipsilateral fingertips was improved. Then, twelve persons with diabetic visually impairment were recruited. Menthol was applied to the forearm on the same side as the index finger used for Braille reading and a placebo was on the contralateral side as a control. Tactile perception test and Braille reading task were carried out before and after application. Application of Menthol to the forearm was suggested to provide improvement in tactile perception of the finger tips and improvement in the accuracy of Braille reading. Further methodological studies and studies to investigate the cortical mechanisms are needed.
