The purpose of this study was to determine differences in somatosensation between older adults with and without type 2 diabetes among three age groups (60s, 70s, and 80s). We recruited 67 adults with type 2 diabetes and 67 age-matched adults without diabetes, aged 60-85. Data were collected using measures in Somatosensory Domain of the National Institute of Health (NIH) Toolbox. We found significant differences in the total scores of five tests examining kinesthesia, tactile sensation, and stereognosis among the three age groups. For all significant differences, the nondiabetes group and those in their 60s and 70s had better functioning than the diabetes group and those in their 80s. The NIH Toolbox-Somatosensory Tools used in this study may be more suitable to discriminate among age groups rather than diagnostic groups.
