Summary
A new Kraftsimulator Intraoperative Pedographie (KIOP) device enables valid intraoperative static pedography. This new method showed no significant force distribution differences compared to traditional static pedography in anesthetized patients.
Area of Science:
- Biomechanics
- Medical Device Engineering
- Podiatry
Background:
- Intraoperative static pedography is a novel technique.
- Validation of this method against standard dynamic and static pedography is crucial.
Purpose of the Study:
- To validate a new intraoperative static pedography device, the Kraftsimulator Intraoperative Pedographie (KIOP).
- To compare KIOP measurements with standard dynamic and static pedography methods.
Main Methods:
- Developed the Kraftsimulator Intraoperative Pedographie (KIOP) device for standardized force application.
- Conducted validation in two steps: healthy volunteers and patients under anesthesia.
- Utilized custom-made pedography mats and statistical analysis (ANOVA, t-test).
Main Results:
- No significant differences in hindfoot to midfoot-forefoot force distribution across all measurements.
- Significant differences in medial-lateral and 10-region mapping when comparing all measurements or only healthy volunteers.
- No significant differences in force distribution for patients under anesthesia compared to awake or between different anesthesia types.
Conclusions:
- The Kraftsimulator Intraoperative Pedographie (KIOP) device is validated for accurate intraoperative static pedography.
- Intraoperative static pedography in the supine position yields comparable results to standing static pedography, even under anesthesia.
