Hypothesis
The study investigates how total contact casts redistribute weight-bearing forces across the foot.
Conclusion
The study reveals that total contact casts reduce maximum pressure at ulcer sites compared to running shoes.
Supporting Evidence
- The maximum pressure in the total contact cast was lower than in the running shoe for both participants.
- The healthy participant had mean maximum pressures of 224 kPa in the running shoe and 159 kPa in the TCC.
- The diabetic participant had mean maximum pressures of 337 kPa in the running shoe and 177 kPa in the TCC.
Takeaway
This study looks at how special casts help reduce pressure on foot ulcers by spreading weight more evenly.
Methodology
Capacitance sensors were used to map load transfer between the leg and cast wall in one healthy and one diabetic participant while walking.
Participant Demographics
One healthy participant and one diabetic participant.
