Self-assessment and objective determination of dexterity in patients with type 1 or type 2 diabetes mellitus.

OBJECTIVE: Insulin-treated patients perform complex treatment activities during daily routine, such as blood glucose measurements and insulin injections. We aimed to identify suitable dexterity and cognitive function tests for diabetes patients, and to compare the patient self-assessment of their dexterity skills with the test results (Jebsen-Taylor hand function test, (JHFT), motoric performance test (MLS), number connection test). METHOD: We enrolled 90 diabetes patients (36 females, 54 males): 15 type 1 with clinically suspected dexterity impairment (A: age: 60 ± 9 years), 30 type 2 with clinically suspected dexterity impairment (B: 61 ± 10 years), 30 type 1 or type 2 patients with visual impairment (C: 64 ± 6 years), and 15 type 1 or type 2 patients without obvious impairment (control group: D: 64 ± 5 years). RESULTS: There were no differences regarding neuropathy and slight impairments in the number connection test in all groups. Patient self-assessment revealed that 33.4% in group A, 33.3% in group B, 36.7% in group C and 13.7% in group D, considered themselves to have dexterity impairment. However in the JHFT test, all patients from A (100%) and B (100%), 33% from C, and 0% from D presented with dexterity impairment by only passing less than four subtests. CONCLUSIONS: Impairment of dexterity was much more frequent than believed by the patients themselves. It may be worthwhile to consider these findings when classifying patients regarding their capabilities to perform certain treatments or when assessing diabetes technology with human subjects.

Use of a virtual human performance laboratory to improve integration of mathematics and biology in sports science curricula in Sweden and the United States.

New fields such as bioengineering are exploring the role of the physical sciences in traditional biological approaches to problems, with exciting results in device innovation, medicine, and research biology. The integration of mathematics, biomechanics, and material sciences into the undergraduate biology curriculum will better prepare students for these opportunities and enhance cooperation among faculty and students at the university level. We propose the study of sports science as the basis for introduction of this interdisciplinary program. This novel integrated approach will require a virtual human performance laboratory dual-hosted in Sweden and the United States. We have designed a course model that involves cooperative learning between students at Göteborg University and Stanford University, utilizes new technologies, encourages development of original research and will rely on frequent self-assessment and reflective learning. We will compare outcomes between this course and a more traditional didactic format as well as assess the effectiveness of multiple web-hosted virtual environments. We anticipate the grant will result in a network of original faculty and student research in exercise science and pedagogy as well as provide the opportunity for implementation of the model in more advance training levels and K-12 programs.
