Relationship between sensibility and ability to read braille in diabetics.
Twenty-five vision-impaired diabetics received an evaluation of sensibility. Each subject had received 2 years of instruction in braille reading at the Konan Rehabilitation Center prior to the sensibility testing. Sensibility evaluation consisted of cutaneous pressure threshold measurements with the Semmes-Weinstein monofilament and evaluation of moving and static two-point discrimination with Disk-Criminator. The ability to read braille was graded by the braille-teaching instructors as good, fair, and unable. The results of the evaluation of sensibility demonstrated that the value of the cutaneous pressure threshold did not correlate with the ability to read braille. Moving and static two-point discrimination were found to correlate highly (P less than .001) with the ability to read braille at a level of fair or good. No patient in this study with a moving two-point discrimination value of 4 or more or a static two-point discrimination value of 5 or more was able to read braille even at the fair level of ability.
