Hypothesis
The mechanical properties of the heel fat pad may influence the severity of heel pain.
Conclusion
The viscosity of the heel fat pad may play a significant role in the severity of heel pain, rather than its elasticity.
Supporting Evidence
- The heel pad's initial stiffness was significantly lower than its final stiffness.
- Peak deformation of the fat pad approached the limit of pain tolerance.
- Energy loss in symptomatic limbs was correlated with the thickness of the plantar fascial enthesis.
Takeaway
The heel pad helps absorb shock when we walk, and its properties can affect how much pain we feel in our heels.
Methodology
Experiments using a digital fluoroscope and pressure platform to measure heel pad mechanics during gait.
Limitations
The study may not fully capture the in vivo mechanics of the heel pad due to the complexity of measuring these properties.
