Type of Research Project
- Basic science
What is the background of the project?
Diabetic neurapathic patients always have a problem about foot sensation loss. This problem causes high pressure site on the patient’s foot without notice and it leads to foot pressure ulcer. In 2017, we have collected data from diabetic neuropathy patients for different activities such as level walking, ramp walking and stair walking. We analyzed these data only 3 regions of foot (forefoot, midfoot and rear foot) as we published in the Foot & ankle international. 2017 Aug;38(8):901-8. However, it still lacks of correlations about the foot regions, plantar pressure distribution and walking activities. As there are about 10 regions of the foot but a few researches carried out to investigate all these regions, we would like to analyze and understand the correlations between plantar pressure and 10 foot regions. It will be useful information for over-pressure prevention for neuropathic foot. In addition, these analyzed data will benefitial for an insole design for plantar pressure and foot pain relief. We also aim to design a pattern and shape of insole for plantar pressure reduction.
What is the aim of the project?
To analyze the biomechanical parameters of foot during the walking activities in diabetic neuropathy patients for an insole design.
What techniques and methods are used?
The steps in this project are as follow 1. Data analysis The data from the diabetic neuropathy patients will be analyzed with Pedar software. Peak plantar pressure, center of pressure and force-time integral will be determined. 2. Statistic analysis The data will be performed statistical analysis using Prism software. The t-test and 1-way analysis of variance (ANOVA) will be applied to these data. 3. Correlation determination The data of plantar pressure distribution, 10 foot regions and walking activities will be studied and made the correlation using linear regression, multi-variance correlation. 4. Insole design A nove idea about the insole will be initiated and brainstromed. The design will be performed in SolidWorks software. This software is a computer aided design (CAD).
What is the role of the student?
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
The student should perform data analysis for peak plantar pressure, center of pressure and force-time integral from the diabetic neuropathy patients using Pedar software. When the data has been extracted and analyzed from Pedar software, then the student has to use the statistical analysis tools in Prism software to perform an unpaired t-test and 1-way analysis of variance (ANOVA). The statistical analysis between walking activities and foot regions has to detemined. Furthermore, using the analyzed data, the student will be able to give the innovative ideas on the insole design, including trying to use SolidWorks-a computer-aided design (CAD) software to design an insole. This novel design will give a benefit for plantar pressure reduction. The student can be able to present the results obtained from the analysis to other students to share the finding of the work.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
The student are expected to attend special seminars by our faculty staff and join the group meeting for literature review presentation by the laboratory members.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student will prepare an abstract - The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
The student should be able to communicate in English well and know about fundamental statistics.
Are there any legal limitations in the student’s involvement
