I am interested in improving the functionality of an educational CD on how to interpret MRI’s of the foot and ankle. In other words, make the CD more “user friendly.” As such, a student with an interest in computer technology is needed to complete the project. Past experience in instructional design would be beneficial, but not necessary. Interested students will have the opportunity to meet with me, examine the current CD, and decide if they have the computer knowledge to participate.
Much of what is taught and practiced in the field of podiatric biomechanics is based on theory and not actual observation. This study will attempt to show that one of the founding principles of this area is potentially flawed; namely, that the heel during gait assumes at some point its neutral position, a position advocated by one of the founders of biomechanical theory, Dr. Merton Root. We believe, as does some current literature, that the heel never reaches neutral position. Rather, it is maintained throughout the gait cycle in a position of valgus which is regarded as a very unstable position. This has major implications for orthosis fabrication since podiatrists take the vast majority of cast impressions of the foot in neutral position. By determining heel position non-weightbearing in the manner described by Root and comparing it to the position during gait as measured in the DMU Human Performance Lab, we hope to shed light on this controversy.
Painful diabetic neuropathy in the feet is a significant problem that is unresponsive to most treatments. We are investigating the effect of a novel use of an anesthetic agent in cream form to see if topical treatment can be successful in diminishing foot pain in diabetics.
